Description

DERIVATIVES OF DIBENZOCROMENO AND ITS USE AS SELECTIVE LIGANDS OF E BETA Field of the Invention This invention relates to novel substituted 5H-dibenzo [c, g] chromene derivatives, their uses as estrogenic agents, and methods for their preparation. Background of the Invention The pleiotropic effects of estrogens in mammalian tissues have been well documented, and it is now appreciated that estrogens affect many organ systems [Mendelsohn and Aras, New England Journal of Medicine 340: 1801-1811 (1999), Epperson, et al., Psychsomatic Medicine 61: 676-697 (1999), Crandall, Journal of omens Health & Gender Based Medicine 8: 1155-1166 (1999), Mon and Brodaty, Dementia & Geriatric Cognitive Disorders 11: 1-10 (2000), Hurn and Macrae, Journal of Cerebral Blood Flow & Metabolism 20: 631-652 (2000), Calvin, Maturitas 34: 195-210 (2000), Finking, et al., Zeitschrift fur Kardiologie 89: 442-453 (2000), Brincat, Maturitas 35: 10-117 (2000), Al-Azzawi, Postgraduate Medical Journal 77: 292-304 (2001)]. Estrogens can exert effects on tissues in several ways. Probably, the most well-characterized mechanism of action is its interaction with estrogen receptors that lead to alterations in gene transcription. The .estrogen receptors are REF: i75298 activated ligand transcription factors and belong to the nuclear hormone receptor superfamily. Other members of this family include the progesterone, androgen, glucocorticoid and mineralocorticoid receptors. By binding the ligand, these receptors are dimerized and can activate genetic transcription by either directly linking to specific sequences in DNA (known as response elements) or by interacting with other transcription factors (such as APIs), which at their they bind directly to specific DNA sequences [Moggs and Orphanides, EMBO Reports 2: 775-781 (2001), may, et al., Journal of Biological Chemistry 276: 36869-36872 (2001), McDonnell, Principles of Molecular Regulation, p351-361 (2000)]. A class of "corregulatory" proteins can also interact with the ligand bound receptor and further modulate their transcriptional activity [McKenna, et al., Endocrine Reviews '20: 321-344 (1999)]. It has also been shown that estrogen receptors can suppress transcription mediated by NFKB in both a ligand-independent and dependent manner [Quaedackers, et al., Endocrinology 142: 1156-1166 (2001), Bhat, et al., Journal of Steroid Biochemistry & Molecular Biology 67: 233-240 (1998), Pelzer et al., Biochemical & Biophysical Research Communications 286: 1153-7 (2001)]. Estrogenps receptors can also be activated by phosphorylation. This phosphorylation is mediated by growth factors such as EGF and causes changes in gene transcription in the absence of the ligand [Moggs and Orphanides, EMBO Reports 2: 775-781 (2001), Hall, et al., Journal of Biological Chemistry 276 : 36869-36872 (2001)]. A less well characterized means by which estrogens can affect cells is through the so-called membrane receptor. The existence of such a receptor is controversial, but it has been well documented that estrogens can produce very rapid non-genomic responses from cells. The molecular entity responsible for transducing these effects has not been definitively isolated, but there is evidence to suggest that it is at least related to the nuclear forms of estrogen receptors [Levin, Journal of Applied Physiology 91: 1860-1867 (2001), Levin, Trends in Endocrinology & Metabolism 10: 374-377 (1999)]. Two estrogen receptors have been discovered to date. The first estrogen receptor was cloned approximately 15 years ago and is now referred to ERa [Green, et al., Nature 320: 134-9 (1986)]. The second was comparatively recently discovered and is called ERß [Kuiper, et al., Proceedings of the National Academy of Sciences of the United States of America 93: 5925-5930 (1996)]. Early development in ERβ focused on defining its affinity for a variety of ligands and, in effect, some differences with ERa was observed. The tissue distribution of ERβ has been mapped well in the rodent and is not coincident with ERa. Tissues such as mouse uterus and rat predominantly express ERa, while mouse and rat lung predominantly express ERβ [Couse, et al., Endocrinology 138: 4613-4621 (1997), Kuiper, et al., Endocrinology 138 : 863-870]. - _ Even within the same organ, the distribution of ERa and Erß can be shared. For example, in the mouse ovary, ERß. it is highly expressed in granulosa cells and ERa is restricted to fecal and stromal cells [Sar and Welsch, Endocrynology 140: 963-971 (199-9), Fitzpatrick, et al., Endocrynology 140: 2581-2591 (1999) ] However, there are examples where the receptors are co-expressed and there is evidence from in vitro studies that ERa and ERß can form heterodimers [Cowley, et al. , Journal of Biological Chemistry 272: 19858-19862 (1997)]. The most potent endogenous estrogen is 17β-estradiol. A large number of compounds have been described that either mimic or block the activity of 17β-estradiol. Compounds that have approximately the same biological effects as 17β-estradiol are referred to as "estrogen receptor agonists". Those which block the effects of 17β-estradiol, when given in combination with it, are called "estrogen receptor antagonists". Actually there is a continuum between the activity of the estrogen receptor agonist and the estrogen receptor antagonist and indeed some compounds behave as estrogen receptor agonists in some tissues but estrogen receptor antagonists in others. These compounds with mixed activity are called selective estrogen receptor modulators (SERMS) and are therapeutically useful agents (eg EVISTA) [McDonnell, Journal of the Society for cologic Investigation 7: S10-S15 (2000), Goldstein, et al., Human Reproduction Update 6: 212-224. (2000)]. The precise reason why the same compound may have the specific effects on cells has not been elucidated, but differences in conformation of the receptor and / or coregulatory protein environment have been suggested. It has been known for some time that estrogen receptors adopt different conformations when they bind ligands. However, the consequence and delicacy of these changes has only recently been revealed. The three-dimensional structures of ERa and ERβ have been solved by co-crystallization with several ligands and clearly show the repositioning of helix 12 in the presence of an estrogen receptor antagonist, which sterically hinders the protein sequences required for coregulatory protein interaction of the receptor [Pike, et al., E bo 18: 4608-4618 (1999), Shiau et al., Cell 95: 927-937 (1998)]. In addition, the phage display technique has been used to identify peptides that interact with estrogen receptors in the presence of different ligands [Paige, et al., Proceedings of the National Academy of Sciences of the United States of America 96: 3999- 4004 (1999)]. For example, a peptide distinguishing between ERa linked to the total estrogen receptor agonists 17β-estradiol and diethylstilbesterol is identified. A different peptide is shown to distinguish between clomiphene linked to ERa and ERβ. These data indicate that each ligand potentially places the receptor in a unique and non-predictable conformation that has a probability to have two distinct biological activities. As mentioned above, estrogens affect a collection of biological processes. In addition, where gender differences have been described (eg frequencies of the disease, responses to the challenge, etc.), the explanation may imply the difference in estrogen levels between males and females.

The compounds of this invention can be used as estrogen receptor modulators useful in the treatment or inhibition of conditions, disorders, or disease states that are at least partially mediated by a deficiency or excess of estrogen, or which can be treated or inhibited through the use of an estrogenic agent. The compounds of this invention are particularly useful for treating a perimenopausal, menopausal or postmenopausal patient in which the levels of endogenous estrogens produced are greatly reduced. Menopause is generally defined as the natural menstrual period and is characterized by the cessation of ovarian function, leading to the substantial decrease of circulating estrogen in the bloodstream. As used herein, menopause also includes conditions of decreased estrogen production that can be surgically, chemically, or caused by a disease state which leads to a premature decline or cessation of ovarian function. Therefore, the compounds of this invention can be used to treat or inhibit osteoporosis and in the inhibition of bone demineralization, which can result from an imbalance in the formation of new bone tissues and the reabsorption of older tissues of the individual, leading to a net loss of bone. Such bone depletion results in a range of individuals, particularly in postmenopausal women who have undergone bilateral oophorectomy, those who receive or who have received extended corticosteroid therapies, those who experience gonadal dysgenesis, and those who suffer from Cushing's syndrome. The special needs for bone, including teeth and oral bone, replacement can also be managed using these compounds in individuals with bone fractures, defective bone structures, and those receiving bone-related surgeries and / or prosthetic implantation. In addition to those problems described above, these compounds can be used in treatment or inhibition for osteoarthritis, hypocalcemia, hypercalcemia, Paget's disease, osteomalacia, osteohalistresis, multiple myeloma and other forms of cancer that have harmful effects on bone tissues. The compounds of this invention are also useful for treating or inhibiting the growth of abnormal benign or malignant tissue, including prostatic hypertrophy, uterine leiomyomas, breast cancer, endometriosis, endometrial cancer, polycystic ovary syndrome, endometrial polyps, benign breast disease, Ovarian cancer, melanoma, prostate cancer, colon cancers, CNS cancers, such as glioma or astioblastomy. The compounds of this invention are cardioprotective and are useful for lowering cholesterol, triglycerides, Lp (a), and LDL levels; inhibit or treat hypercholesterolemia; hyperlipidemia; cardiovascular disease, atherosclerosis, peripheral vascular disease; restenosis and vasospasm and inhibit vascular wall damage from cellular events that lead to vascular damage mediated by immunity. These protective cardiovascular properties are of great importance when treating postmenopausal patients with estrogen to inhibit osteoporosis and in the male when estrogen therapy is indicated. The compounds of this invention are also antioxidants, and are therefore useful for treating or inhibiting disease states induced by free radicals. The specific situations in which the antioxidant therapy is indicated to be guaranteed are with cancers, disorders of the central nervous system, Alzheimer's disease, bone disease, aging, inflammatory disorders, peripheral vascular disease, rheumatoid arthritis, autoimmune diseases, respiratory dysfunction, emphysema, prevention of reperfusion damage, viral hepatitis, chronic active hepatitis, tuberculosis, psoriasis, systemic lupus erythematosus, adult respiratory dysfunction syndrome, central nervous system trauma and infarction. The compounds of this invention are also useful for providing increased cognition, and for treating or inhibiting senile dementias, Alzheimer's disease, cognitive decline, neurodegenerative disorders, providing neuroprotection or increased cognition. The compounds of this invention are also useful for treating or inhibiting inflammatory bowel disease, ulcerative proctitis, Crohn's disease, and colitis; menopausal related conditions, such as vasomotor symptoms including hot flashes, vaginal or vulvar atrophy, atrophic vaginitis, vaginal dryness, prutitus, dyspareunia, dysuria, frequent urination, urinary incontinence, urinary tract infections, vasomotor symptoms, including hot flashes, myalgia, arthralgia, insomnia , irritability and the like; male pattern baldness; skin atrophy; acne; type II diabetes; dysfunctional uterine bleeding and infertility. The compounds of this invention are useful in disease states where amenorrhea is advantageous, such as leukemia, endometrial ablations, chronic kidney or liver disease or diseases or coagulation disorders. The compounds of this invention can be used as a contraceptive agent, particularly when combined with progestin. When administered for the treatment or inhibition of a particular disease state or disorder, it is understood that the effective dose may vary depending on the particular compound used, the mode of administration, the condition, and severity thereof, of the condition that is treated, as well as the various physical factors related to the individual being treated. The effective administration of the compounds of this invention can be given in an oral dose of about 0.1 mg / day to about 1,000 mg / day. Preferably, the administration will be from about 10 mg / day to about 600 mg / day, more preferably from about 50 mg / day to about 600 mg / day, in a single dose or in two or more divided doses. The projected daily doses are exposed to vary the route of administration.
Such doses may be administered in some useful way to direct the active compounds of the present to the bloodstream of the recipient, including orally, by means of implants, parentally (including intravenous, intraperitoneal and subcutaneous injections), rectally, intranasally, vaginally and transdermally . Oral formulations containing the active compounds of this invention may comprise any oral forms conventionally used, including tablets, capsules, buccal forms, troches, lozenges, and liquids, suspensions or oral solutions.

The oral formulation may also consist of administering the active ingredient in water or a fruit juice, which contains the appropriate solubilizers or emulsifiers as necessary. In some cases it may be desirable to administer the compounds directly to the respiratory tract in the form of an aerosol. The compounds of this invention may also be administered parentally or intraperitoneally.

This test procedure provides the methodology for determining if a. particular compound binds to the estrogen receptor (and is therefore "estrogenic") and if there is selectivity for ERa or ERβ. The values in the Table below are shown and reported as IC50S- The 17ß-estradiol is included as a standard reference for comparison. The procedure used is described briefly below. An unpurified lysate of E. coli is prepared which expresses the ligand binding domains of the estrogen receptor (D, E, and F) of human ERa or ERβ. Both receptors and compounds are diluted in Dulbecco's PBS once (DPBS) supplemented with 1 M EDTA. Using a high-binding masked microtiter plate, 100 μl of the receptor (luG / well) is combined with 2 nM [3H] -17β -stradiol and various concentrations of the compound. After 5 to 15 hours at room temperature, the plates are washed with DPBS / 1 mM EDTA and bound radioactivity determined by liquid scintillation counting. The IC50 is defined as the concentration of the compound that decreases the binding of total 17β-estradiol by 50%. The results obtained are described in the following table.
The results obtained in the standard pharmacological test procedure demonstrate that the compounds of this invention are estrogenic compounds, some with strong preferential affinity for the ERβ receptor. The compounds of this invention are in the range that have high preferential affinity for ERβ on ERa for almost an equal affinity for both receptors. In this way, the compounds of this invention will extend a range of activity based, at least partially, on their receptor affinity selectivity profiles. Additionally, since each novel receptor ligand complex is unique and. in this way in interaction with several coregulatory proteins, the compounds of this invention will exhibit different modulator behavior depending on the cellular context in which they are. For example, in some cell types, it is possible for a compound to behave as an estrogen agonist while in other tissues, as an antagonist. Compounds with such activity have sometimes been referred to as SERMs (selective estrogen receptor modulators). Unlike estrogen, however, many of the SERMs do not cause increases in wet uterine weight. These compounds are antiestrogenic in the uterus and can completely antagonize the trophic effects of estrogen agonists in uterine tissue. These compounds, however, act as estrogen agonists in bone, cardiovascular and central nervous system systems. Due to this tissue-selective nature of these compounds, they are useful for treating or preventing conditions or syndromes of mammalian disease which are caused or associated with an estrogen deficiency (in certain tissues such as bone or cardiovascular) or an excess of estrogen. (in the uterus or mammary glands). Even beyond such cell-specific modulation, the compounds of this invention also have the potential to behave as agonists in one type of receptor while behaving as antagonists in the other. For example, it has been shown that the compounds can be an antagonist on ERβ while being an agonist in ERa (Meyers, Marvin J .; Sun, Jun; Carlson, Kathryn E .; Katzenellenboen, Benita S.; Katzenellenbogen John A., J. Med. Chem. (1999), 42 (13), 2456-2468). Such ERSAA activity (selective estrogen receptor agonist antagonist) provides pharmacologically distinct estrogenic activity within this series of compounds. Standard pharmacological test procedures are readily available to determine the activity profile of a given test compound. The following examples briefly summarize several representative test procedures. The standard pharmacological test procedures for SERM are also provided in U.S. Patents 4,418,068 and 5,998,402. EXAMPLE 65 Rat uterotrophic / antiuterotrophic test procedure The estrogenic and antiestrogenic properties of the compounds can be determined in an immature rat uterotrophic assay (4 days) as previously described by L. J. Black and R.L. Goode, Life Sciences, 26, 1453 (1980). Immature Sprague-Dawley rats (female, 18 days old) are tested in groups of six. They are treated. animals by ip injection daily with 10 uG of compound, 100 uG of compound, (100 uG of compound + 1 uG of 17β-estradiol) to check the antiestrogencity, and 1 uG of 17β-estradiol, with 50% DMSO / solution 50% saline as the injection vehicle. On day 4 the animals are sacrificed by asphyxiation with C02 and the uterus is removed and the excess lipids are removed, any fluid is removed and the wet weight is determined. A small horn section is subjected to histology and the remainder is used to isolate the total RNA in order to evaluate the gene expression of the complement component 3. Example 66 Test procedure of 6-week ovarianized rat-bone and cardioprotection the rats CD Sprague Dawley Female, ovx or sham ovx, 1 day after surgery Taconic Farm (weight range 240-275 g). They lodge 3 or 4 rats / cage in a room in program 12/12 (light / dark) and they are provided with food (Purina 5K96C rat food) and water ad libitum. Treatment for all studies begins 1 day after the animals arrive and are dosed 7 days per week as indicated for 6 weeks. A group of simulated sham-operated rats receive no treatment and serve as a control group replete with estrogen. intact for each study. All treatments are prepared in 1% Tween 80 in normal saline at defined concentrations such that the volume of treatment is 0.1 ml / 100 mg of body weight. 17β-estradiol is dissolved in corn oil (20 μg / ml) and supplied subcutaneously, 0.1 ml / rat. All doses are adjusted at three-week intervals according to the group's average body weight measurements. Five weeks after the start of treatment and one week before the end of the study, each rat is evaluated for bone mineral density (BMD). The total and trabecular density of the proximal tibia in anaesthetized rats is evaluated using an XCT-960 M (pQCT); Stratec Medizintechnik, Pforzheim, Germany). The measurements are made as follows: Fifteen minutes before the scan, each rat is anesthetized with an intraperitoneal injection of 45 mg / kg of ketamine, 8.5 mg / kg of xylazine, and 15 mg / kg of acetopromazine.
The right rear leg is passed through a polycarbonate tube with a diameter of 25 mm and covered with an acrylic box with the ankle joint at a 90 ° angle and the knee joint at 180 °. The polycarbonate tube is fixed in a sliding platform that maintains its perpendicular to the pQCT opening. The platform is adjusted in such a way that the distal end of the femur and the proximal end of the tibia can be in the sweep field. A two-dimensional explorer view is run by a length of 10 mm and a line resolution of 0.2 mm. After the exploratory view is displayed on the monitor, the proximal end of the tibia is located. The pQCT scan is started 3.4 mm distal from this point. The pQCT scan is 1 mm thick, has a voxel size (three-dimensional pixel) of 0.140 mm, and consists of 145 projections through the cut. After the pQCT is completed, the image is displayed on the monitor. A region of interest including the tibia but excluding the fibula is indicated. The soft tissue is automatically removed using an iterative algorithm. The density of the rest of the bone (total density) is reported in mg / cm3. The outer 55% of the bone is removed in a concentric spiral. The density of the remaining bone (Trabecular Density) is reported in mg / cm3. One week after the BMD evaluation, the rats are euthanized by suffocation of carbon dioxide and the blood is collected for cholesterol determination. The uterus is removed and the weights are taken. Total cholesterol is determined - using a Boehringer-Mannhei Hitachi 911 clinical analyzer using the Cholesterol / HP equipment. The statistics are compared using a one-variance analysis with Dunnet's test. EXAMPLE 67 Antiproliferative Test Method MCF-7 / ERE Provision solutions of test compounds (usually 0.1 M) are prepared in DMSO and then diluted 10 to 100 times with DMSO to make development solutions of 1 or 10 mM. The provisions of DMSO are stored at either 4o (0.1 M) or -20 ° C (<0.1 M). The cells are passed MCF-7 twice a week with growth medium [D-MEM / F-12 medium containing 10% heat inactivated fetal bovine serum (v / v), Penicillin-Streptomycin 1% (v / v), and 2 mM glutaMax-1]. The cells are kept in flasks vented in 37 ° C inside a 5% C02 / 95% humidified air incubator. One day before the treatment, cells are plated with growth medium at 25,000 / well in plates with 96 wells and incubated at 37 ° C overnight. Cells are infected for 2 hours at 37 ° C with 50 μl / well of a 1:10 dilution of adenovirus 5-ERE-tk-luciferase in experimental medium [red phenol-free D-MEM / F-12 medium containing separate fetal bovine serum with 10% heat activated charcoal (v / v), 1% Penicillin-Streptomycin (v / v), glutaMax-1, 1 mM sodium pyruvate]. The wells are then washed once with 150 μ? of experimental medium. Finally, the cells are treated for 24 hours at 37 ° C in duplicates of 8 wells / treatment with 150 μ? / Well vehicle (<0.1% DMSO v / v) or compound that is diluted > 1000 times in experimental medium. The initial screening of the test compound is done in a single dose of 1 μM which is tested alone (agonist mode) or in combination with 0.1 nM 17β-estradiol (EC8o, antagonist mode). Each 96-well plate also includes a vehicle control group (0.1% DMSO v / v) and an agonist control group (either 17β-estradiol 0.1 or 1 nM). The dose response experiments are performed in either the agonist and / or antagonist modes on active compounds in log increments of 10 ~ 14 to 10"5 M. From these dose response curves, EC50 and IC50 values are generated. The final well in each treatment group contains 5 μl of M IC-182,780 3 xlO "5 (final concentration 10" 6M) as an ER antagonist control After the treatment, the cells are used in a shaker for 15 minutes. minutes with 25 μl / well of cell culture lysis reagent 1 time (Promega Corporation) Cell lysates (20 μl) are transferred to a 96-well luminometer plate and the activity of luciferaza is measured in a MicroLumat Lb luminometer 96 P (EG & G Berthold) using 100 μl / well of luciferaza substrate (Promega Corporation). Before the injection of the substrate, a background measurement of 1 second is made for each well. After injection of the substrate, the activity of the luciferase is measured for 10 seconds after a delay of 1 second. The data is transferred to a Macintosh personal computer and analyzed using the JMP (SAS Institue) software: this program subtracts the above reading from the luciferaza measurement for each well and then determines the average and standard deviation of each treatment. The luciferaza data are transformed by algorithms, and the Huber M estimate is used to decrease the weight of the underlined transformed observations. The software is used to analyze the transformed and weighted data for ANOVA in one way (Dunnett's test). The treatments of the compound are compared to the vehicle control results in the agonist mode, or the positive agonist control results (0.1 nM 17β-estradiol) in the antagonist mode. For the initial single dose experiment, if the results of the compound treatment are significantly different from the appropriate control (p <0.05), then the results are reported as the percent relative to the control of 17β-estradiol [ie, ( (Compound-vehicle control) / (control of 17ß-estradiol-vehicle control)) x 100]. The JMP software is also used to determine the EC50 and / or IC50 values from the non-linear dose response curves. Example 68 Inhibition of LDL oxidation-antioxidant activity Porcine aortas are obtained from a slaughterhouse, washed, transported in cold PBS, and aortic endothelial cells are harvested. To harvest the cells, the intercostal vessels of the aorta are tied, and one end of the aorta is held. The 0.2% collagenase, sterile filtered, fresh (Sigma Type I) is placed in the beaker and the other end of the beaker is clamped to form a closed system. The aorta is incubated at 37 ° C for 15-20 minutes, after which the collagenase solution is collected and centrifuged for 5 minutes at 2000 x g. Each granule is suspended in 7 ml of endothelial cell culture medium consisting of FEM medium DMEM / Ham free of phenol red supplemented with FBS separated with carbon / 5%), NuSerum (5%), L-glutamine (4 mM) ), penicillin-streptomycin (1000 U / ml, 100 μg / ml) and gentimycin (75 μg / ml), is seeded in 100 mm petri dishes and incubated at 37 ° C in 5% C02. After 20 minutes, the cells are rinsed with PBS and fresh medium is added, this is repeated again in 24 hours. The cells are confluent after about 1 week. The endothelial cells are fed routinely twice a week and, when they converge, trypsinize and are sown in a 1: 7 ratio. Cell-mediated oxidation of 12.5 μg / ml of LDL is allowed to proceed in the presence of the compound to be evaluated (5 μM) for 4 hours at 37 ° C. the results are expressed as the percent inhibition of the oxidative process as measured by the TBARS method (thiobarbituric acid reactive substances) for analysis of free aldehydes (Yagi K., Biochemical Méd 15: 212-216 (1976)). EXAMPLE 69 D12 Hypothalmic Cell Test Procedure Dotal rat hypothalamic cells are subcloned from the parental cell line RCF17 and stored frozen. Routinely grown in DMEM: F12 (1: 1), glutaMAX-1 (2 mM), penicillin (100 U / ml) -streptomycin (100 mg / ml), plus 10% fetal bovine serum (FBS). The cells are plated in phenol red free medium (DMEM-F12, glutaMAX, penicillin-streptomycin) containing separate FBS with 2-10% carbon at a confluent density (1-4 x 10 <6> cells). / 150 mm disk). The cells are fed 24 hours later with medium containing 2% separate serum: To test the agonist activity, the cells are treated with 17β-estradiol nM or several doses of test compound (lmM or a range of 1 pM to 1 mM). To test the antagonist activity cells are treated with 0.1 nM 17β-estradiol in the absence or presence of varied doses (100 pM to 1 mM) of test compound. The control boxes are also treated with DMSO as a negative control. Forty-eight hours after the addition of the hormone, the cells are lysed and the binding test procedure is performed. For each binding test procedure, 100-150 mg of protein is incubated with 10 nM 3H-R5020 + 100 times excess of R5020 in a volume of 150 ml. Triplicate reactions (three with R5020, three without R5020) are prepared in a 96-well plate. The protein extract is first added followed by 3H-R5020 + lOOx not labeled R5020. The reaction is carried out for 1-2 hrs at room temperature. The reaction is stopped by the addition of 100 ml of 5% carbon (Norit SX-4), 0.5% dextran 69K (Pharmacia) in TE pH 7.4. After 5 minutes at room temperature, bound and unbound ligand are separated by centrifugation (5 minutes, 100 RCF, 4 ° C). The supernatant solution is removed (-150 ml) is removed and transferred to a scintillation vial. After the addition of scintillation fluid (Beckman Ready Protein +), the samples are counted for 1 minute in a scintillation counter. EXAMPLE 70 Progesterone Receptor in the Preoptic Area of the CNS Sixty (60) day old female Sprague-Dawley rats are ovarioctomized. The animals are housed in an animal care facility with a photoperiod of 12 hours of light, 12 hours of darkness and free access to running water and rodent food. The ovariectomized animals are randomly divided into groups that are injected with vehicle (50% DMSO, 40% PBS, 10% ethanol vehicle), 17β-estradiol (200 ng / kg) or the compound to be tested. The additional animals are injected with the test compound 1 hour before the injection of 17β-estradiol to evaluate the antagonistic properties of this compound. Six hours after the s.c. injection, the animals are euthanized with a lethal dose of C02 and their brains are collected and frozen. The tissue collected from animals is cut in a cryostat at -16 ° C and collected in slides on a slide coated with silane. Sectioned cuts are then dried in a cutting heater maintained at 42 ° C and stored in cut-off boxes at -80 ° C. Before processing, the dissected cutting boxes are heated slowly to room temperature (-20 ° C for 12-16 hours, 4 ° C for 2 hours, room temperature for 1 hour) to eliminate the formation of condensation in cuts and from this shape minimizes tissue and degradation of AKN. The dry cuts are loaded onto metal shelves, post-set in 4% paraformaldehyde (pH 9.0) for 5 minutes and processed as previously described.
A plasmid that "contains an 815 bp fragment of the PR 9 cDNA (ligand binding domain) and is used to generate a probe labeled S 35 -UTP that is complementary to a portion of the rat mRNA PR is linearized. Processed section assemblies are hybridized with 20 ml of hybridization mixture containing the riboprobe (4-6 xlO 6 DPM / cut) and 50% formamide and incubated overnight in a humidified chamber at 55 ° C. , the sections are placed in metallic shelves that are immersed in 2xSSC (0.15 M NaCl, 0.015 M sodium citrate, pH 7.) / 10 mM DTT The shelves are all transferred to a large container and washed in 2xSSC / DTT 10 M for 15 minutes at room temperature with gentle shaking.The cuts are then washed in RNase buffer at 37 ° C for 30 minutes, treated with RNase A (2 mg / ml) for 30 minutes at 37 ° C, and wash for 15 minutes at room temperature IX SSC Subsequently, the cuts are washed (2 x 20 minutes) at 65 ° C in 0.1X SSC to remove the non-specific label, rinse at room temperature 0.1X SSC for 15 minutes and dehydrate with a graduated series of ammonium acetate: alcohol (70%, 95% and 100%). The air-dried cuts are opposed to an X-ray film for 3 days and then processed photographically. The cuts from all the animals are hybridized, washed, exposed and photographically processed among themselves to eliminate the differences due to the interassay variation in the conditions.
Example 71 Rat fights-effects in the CNS Ovarianized, Sprague-Dawlye rats are obtained from 60 days of age after surgery. Surgeries are done a minimum of 8 days before the first treatment. Animals are individually housed under a 12-hour light / dark cycle and given standard rat food and water ad libitum. Two control groups are included in each study.
Doses are prepared based on mg / kg body weight of the medium group in either 10% DMSO in castor oil (sc studies) or 1.0% tween 80 in saline (studies po). The animals are administered with the test compounds in doses in the range of 0.01 to 10 mg / kg of body weight of the medium group. Vehicle and ethinyl estradiol (EE) controls (0.1 mg / kg, sc or 0.3 mg / kg po) control groups are included in each test. When the compounds are tested for their antagonistic activity. EE is coadministered 0. 1 or 0.3 mg / kg for sc or po studies, respectively. The test compounds are administered until the day when the skin temperature of the tail is measured. After the acclimatization period of four days, the animals are treated once daily with the compound of interest. There are 10 animals / treatment group. The administration of the compound is either by sc injection of 0.1 ml into the neck of the neck or po into a volume of 0.5 ml. On the third day . of the treatment, a granule of morphine (75 mg of morphine sulfate) is implanted subcutaneously. On the 5th day of treatment, one or two additional morphine granules are implanted. On day eight, approximately half of the animals are injected with Ketamine (80 mg / kg, intramuscularly) and a thermocouple connected with a MacLab Data Acquisition system (API Instruments, Milford, MA) is capped with the tail approximately one inch ( 2.54 cm) of the root of the tail. This system allows the continuous measurement of tail fur temperature. The baseline temperature is measured for 15 minutes, then sc (0.2 ml) naloxone (1.0 mg / kg) is given to block the effect of morphine and the tail skin temperature is measured for one hour after this. On day nine, the rest of the animals are fixed and analyzed similarly. Example 72 Vasomotor function in isolated rat aortic rings The Sprage-Dawley rats (240-260 grams) are divided into 4 groups: 1. Non-ovarian normal (intact) 2. ovarianized (ovex) treated with vehicle 3. ovarianized treated with 17β -estradiol (1 mg / kg / day). . ovarianized animals treated with test compound (ie, 1 mg / kg / day) Animals are ovarianized approximately 3 weeks prior to treatment. Each animal receives 1 mg / kg / day of either 17β-estradiol sulfate or test compound suspended in deionized water distilled with 1% Tween-80 by gastric gavage. The vehicle treated animals receive an appropriate volume of vehicle used in the drug treated groups. The animals are euthanized by CO 2 inhalation and exsanguination. Their thoracic aortas are rapidly removed and placed at 37 ° C in physiological solution with the following composition (mM); NaCl (54.7), KCl / 5.0), NaHCO3 (25.0), MgCl2 2H20 (2.5), D-glucose (11.8) and CaCl2 (0.2) gasified with C02-02, 95% / 5% for a final pH of 7.4. The adventitia is removed from the outer surface and the recipient is placed in 2-3 mm wide rings. The rings are suspended in 10 ml of tissue bath with one end attached to the bottom of the bath and the other end to a force transducer. A remaining tension of 1 gram is placed in the rings. The rings are balanced for 1 hour, the signals are acquired and analyzed. After equilibration, the rings are exposed to increased concentrations of phenylephrine (10 ~ 8 to 10 ~ 4 M) and the tension recorded. The baths are then rinsed 3 times with fresh buffer. After washing, 200 mM L-NAME is added to the tissue bath and equilibrated for 30 minutes. The phenylephrine concentration response curve is then repeated.
EXAMPLE 73 Radial Limb Deck of Eight Arms - Increase in Cognition Female Cd, Sprague-Dawley rats (Charles River, Kingston, NY) weighing 200-250 g on arrival are used. For one week, the rats are housed, six per cage, with standard laboratory food and water available ad libitum. The accommodation is a quarter of colony maintained at 22 ° C and has a cycle of 12 light / dark hours with light at 6:00 AM. After becoming accustomed to the installation, the animals are housed individually and kept at 85% free weight. Once stable weights are obtained, the rats are acclimated to the radial mallet of the arm 8. The mallet structure is an adaptation of that of Peele and Baron (Pharmacology, Biochemistry, and Behavior, 29: 143-150, 1988). The mallet is raised to a height of 75.5 cm and is composed of a circular area surrounded by 8 arms radiating from the center, equidistant from each other. Each arm is 58 cm long x 13 cm high. A clear plexilliary cylinder is loaded to enclose the animal in the central portion of the deck before the start of each session. Each arm of the deck is equipped with 3 groups of interconfronted photocells to a data acquisition unit, which in turn interconfronts a computer. The photocells are used to track the movement of the tag in the deck.
The granule feeders located above the cups of food at the end of each arm, dispense two chocolate granules of 45 mg when the outer photocell of the arm is activated for the first time in a given session. The arm is placed in a test room with black and white geometric posters on each wall to serve as visual inputs. During all training and testing procedures, white noise (-70 db) is audible. The training procedure consists of five phases, each with daily sessions that last 5 or 10 minutes. A second delay is imposed between the time the rat is placed in the central portion of the deck and when the cylinder is increased to start the session. During phase I, restricted rat food pairs are placed in the bundle for 10 minutes with 45 mg chocolate feed granules in all 8 arms of the bundle. During Phase II, each rat is placed individually in the deck for a period of 10 minutes, with granules scattered from the middle of the photocell to the food cup of each arm. During Phase III, each rat is placed in the bundle for a period of 10 minutes, with food pellets that are located only in and around cups of food in each arm. In Phase IV, each rat is allowed 10 minutes to collect two granules from each arm. Reentry in an arm is considered an error. Rats are trained daily in this manner until they achieve criterion behavior with less than or equal to 2 total errors on three consecutive days of training. The total habituation and training time is approximately 3 weeks. The test compound is prepared in a buffered saline solution and administered in a volume of 1 ml / kg. Scopolamine HBr (0.3 mg / kg s.c.) serves as the damaging agent, which produces an increase in error ratio (memory loss). The test compound is given intraperitoneally simultaneously with scopolamine, 30 minutes before the first exposure to the mallet on any given test day. To evaluate the test compound, a balanced 8 x 8 Latin box for repeated measurements is designed, in order to achieve high experimental efficiency with at least a number of animals. Eight experimental sessions, two per week, are performed with the 8 treatments (vehicle, scopolamine, 3 dsis of test compound in combination with scopolamine) randomly within each session. Each treatment follows each other treatment the same number of times. Therefore, the residual effect of each treatment can be estimated and removed from the treatment effect. After ANOVA, multiple comparisons are made using a two-sided Dunnett test in the adjusted medium.
Animals that do not make 4 correct choices within 5 minutes during the first exposure, or that do not make a total of 8 choices by the end of the second exposure, are considered to be "out of time" for that session. Any animal that is "out of time" after the administration of more than one dose of the test compound is excluded from the analysis. Example 74 Neuroprotection Inhibition of time-dependent death of cells in primary cortical neuronal cultures Primary cortical neurons are produced from rat brains that are 0-1 day old using a variation of methods described by Monyer et al. 1989, Brain Research 483: 347-354. The brain tissue dispersed in % DMEM / PDHS (pregnant donor horse serum) for three days and then treated with cytosine arabinoside (ARC) for two days to remove the contaminating glia cells. On day 5, the ARC medium is removed and replaced with 10% DMEM / PDHS. Neuronal cells are cultured for an additional 4-7 days before use. The primary control neuronal cultures show progressive cell death between days 12 and 18 in culture. The twelve cultures are evaluated on days 12 and 16 for lactate dehydrogenase (LD) enzyme levels after adding the test compound to 6 cultures maintained in DMEM and 10% PDHS on day 9 and keeping the remaining cultures as the controls. LD is tested using a variation of the method by Wroblewski et al. 1955, Proc. Soc. Exp. Biol .. Med. 90: 210-213. LD is a cytosolic enzyme while it is commonly used in both clinical and basic research to determine tissue viability. An increase in mean LD is directly related to cell death. Neuroprotection against hypoglycemia-induced cytotoxicity C6 glioma cells obtained from ATTC in RPMl medium are plated with FBS at a concentration of 1 x 10 < 1 > cells / ml in FALCON 25 cm2 of tissue culture flasks. Four hours before the onset of hypoglycemia, the maintenance medium is discarded, the monolayers are washed twice in the appropriate medium and then incubated for four hours at 37 ° C in either serum-free or serum-free test compound. plus Kreb's Ringer's phosphate buffer is used to wash the monolayers twice before adding the appropriate treatment with glucose. The RPMl medium contains 2 mg glucose / ml; the flasks are divided into groups of 5 each receiving 100% glucose (2 mg / ml), 80% glucose (1.6 mg / ml), 50% glucose (1.2 mg / ml), or 0% glucose ( buffer) or supplemented with test compound. All flasks are incubated for 20 hours and then evaluated for number of dead, live, and total cells using triptan blue. Neuroprotection against excitotoxic amino acids Five culture plates containing SK-N-SH neuroblastoma cells are treated with test compound and 5 culture plates are treated with RPMl medium. Four hours later, all cells are treated with NMDA (500 mu M) for 5 minutes. The total living cells and the dead cells are then determined. Neuroprotection against oxygenated glucose dehydration Analysis of piknotic nuclei to measure apoptosis: Cortical neurons are prepared from rat fetus E18 and placed on plates in slices of. 9-well chamber pre-coated with poly-D-lysine (10 ng / ml) and serum at a density of 100,000 cells / well. The cells are plated in DMEM concentrated in glucose containing 10% FCS and kept in the incubator at 37 ° C with 10% C02 / 90% air. On the next day, the serum is removed by replacing it with culture medium with concentrated DMEM in glucose containing B27 supplemented and the cells are kept in the incubator without also changing the medium until the day of the experiment. On day 6, the cuts were divided into two groups, control group and OGD group. Cells in the control group receive DMEM with glucose and B27 to taste (without antioxidant). The cells in the OGD group receive DMEM without glucose with B27 to taste, which has been degassed under vacuum for 15 minutes. The cells are flowed with 90% N2 / 10% CO2 for 10 minutes in an air chamber and incubated at 37 ° C for 6 hours. After 6 hours, both the control and the OGD cells are subjected to replacement of medium containing either the vehicle (DMSO) or test compound in DMEM containing glucose with B27 to taste. The cells are returned to a normoxic incubator at 37 ° C. After 24 hours, the cells are fixed in 4% PFA for 10 minutes at 4 ° C and stained with Topro (fluorescent nuclear binding dye). Apoptosis is evaluated using Scanning Cytometer for measuring piknotic nuclei. Measurement of LDH release as an indication of cell death: Cortical neurons are prepared from rat El8 fetus and placed in 48-well culture plates pre-coated with poly-D-lysine (10 ng / ml) and serum in a density of 150,000 cells / well. Cells are plated in DMEM with high glucose concentration containing 10% FCS and kept in the incubator at 37 ° C with 10% C02 / 90% air. The next day, serum is removed by replacing culture medium with DMEM with high concentration of glucose containing B27 complement. On day 6, the cells are divided into two groups: the control group and the OGD group. Cells in the control group receive DMEM without glucose with B27 to taste, which has been degassed under vacuum for 15 minutes. The cells are flowed with 90% N2 / 10% CO2 for 10 minutes in a fixed air chamber and incubated at 37 ° C for 6 hours. After 6 hours, the control cells and OGD are subjected to replacement of medium containing either vehicle (DMSO) or test compound in DMEM containing glucose with B27 to taste. The cells are returned to a normoxic incubator at 37 ° C. After 24 hours, cell death is assessed by measuring the cellular release of LDH (lactate dehydrogenase) in the culture medium. For the LDH assay, an aliquot of 50 μl of culture medium is transferred into the 96-well plate. After the addition of 140 μl of 0.1 M potassium phosphate buffer (pH 7.5) and 100 μl of 0.2 mg / mg of NADH, the plate is left in the dark at room temperature for 20 minutes. Retraction is initiated by the addition of 10 μl of sodium pyruvate. The plate is read immediately at 340 mM on a thermometer plate reader (Molecular Devices). Absorbance is recorded, an index of concentration of NADH, every 6 seconds for 5 minutes and the slope indicating the rate of disappearance of NADH is used to calculate LDH activity. LDH activity (U / ml) = (? A / min) (TCF) (20) (0.0833) / (.78) Where: 0.0833 = constant of proportionality 0.78 = length of light path of the instrument (cm) Example 75 Test procedure Rat HLA- Crohn's Disease and Intestinal Inflammatory Disorders Male HLA-B27 rats are obtained from Taconic and provide unrestricted access to a food (PMI Lab diet 5001) and water. At the start of the study, the rats are 22-26 weeks old. The rats are dosed subcutaneously once per day per site days with one of the formulations listed below. There are five rats in each group and the last dose is administered two hours before euthanasia. • vehicle (50% DMSO / 50% Dulbecco PBS) - • 17a-ethynyl-17β-estradiol (10 μg / kg) • test compound The quality of the feces is observed and they are graduated according to the following scale. Diarrhea = 3, soft stools = 2; normal stools = l. At the end of the test procedure, the serum is collected and stored at -70 ° C. One is prepared. section of the colon for histological analysis and an additional segment for myeloperoxidase activity is analyzed. The following method is used to measure myeloperoxidase activity. The colon tissue is harvested and quick frozen in liquid nitrogen. A representative sample of the entire colon is used to ensure consistency between samples. The tissue is stored at -80 ° C until use. Then, the tissue is weighed (approximately 500 mg) and homogenized in 1:15 p / v of 5 mM H2KP0 (pH 6) wash buffer. The tissue is rotated at 20,000 x g in a Sorvall RC 5B centrifuge for 45 minutes at 2-8 ° C. The supernatant is then discarded. The tissue is resuspended and homogenized in 2.5 ml (1: 5 p / v) of 50 mM H2KP04 with 10 mM EDTA and 0.5% ammonium bromide hexane to help solubilize the intracellular MPO. The tissue is frozen in liquid Nitrogen, thawed in a 37 ° C water bath and sonicated for 15 seconds to ensure membrane lysis. The procedure is repeated 3 times. The samples are then kept on ice for 20 minutes and centrifuged at 12,000 x g for 15 minutes at 2-8 ° C. The supernatant is analyzed following these steps. The test mixture is prepared by adding 2.9 ml of 50 mM H2KP04 with 0.167 O-dianisidine / ml with 0.0005% H202 in a reaction tube. When hydrogen peroxide is degraded, O-dianisidine is oxidized and absorbed at 460 nm in a concentration-dependent manner. The mixture is heated to 25 ° C. One hundred (100) μl of the tissue supernatant is added to the reaction tube, incubated for 1 minute at 25 ° C, then 1 ml is transferred to a disposable plastic cup. The OD is measured every 2 minutes reaction time at 460 nm against a blank containing 2.9 ml of the reaction mixture and 100 μl of the 0.5% ammonium bromide solution.
Enzyme activity units are quantified by comparison of absorbance © 460 for a standard curve prepared with purified human MPO 31.1 units / Vial. The MPO is reconstituted and serially diluted using 50 mM H2KP0 with 10 mM EDTA and 0.5% Ammonium Bromide Hex at four known concentrations. Sample absorbances are compared against this curve to determine activity. The histological analysis is carried out as follows: the colonic tissue is immersed in 10% neutral buffered formalin. Each colon specimen is separated into four samples for evaluation. Solid tissues with formalin are processed in a vacuum infiltration processor for paraffin embedded. The samples are sectioned at 5 μm and then stained with hematoxylin and eosin (H &E) for blind histological evaluations using a modified scale after Boughton-Smith.
After the classifications are completed the samples are not blind, and the data are tabulated and analyzed by linear ANOVA modeling with multiple mean comparisons.
