Description

COMPOUNDS AND METHODS TO PROVIDE PHARMACOLOGICALLY ACTIVE PREPARATIONS AND USES THEREOF FIELD OF THE INVENTION The present invention relates to compounds and their uses for the treatment of the family of the nuclear hormone receptor (NHR) associated with disorders. More specifically, the present invention relates to compounds having a particular 3-dimensional spatial orientation that are capable of binding to and thus altering the function of the NHR. Such compounds would be useful as therapeutic agents for disorders associated with NHRs such as the retinoid receptor x (RXR). The invention also relates to compositions and methods for the treatment or prophylaxis of osteoporosis, bone loss, arthritis, inflammation, cancer and skin conditions.
REF .: 29136 BACKGROUND OF THE INVENTION AND DESCRIPTION OF THE PREVIOUS ART Current modern methods for the discovery of therapeutic agents for the amelioration of major diseases focus on interdisciplinary approaches of molecular biology, enzymology, crystallography, drug synthesis, molecular modeling and pharmacology. The typical approach involves: identification, isolation, purification, and crystallization of a white protein associated with the disease (s) of interest; modeling of the protein link and active sites; and modeling, synthesis and evaluation of compounds to optimize their pharmacological activity. Even with the advanced state of the art, drug discovery and, in particular, prediction of structure-activity relationships, significant effort continues to be required in the part of the pharmaceutical industry. Thus, there remains a need to develop efficient and cost-effective methods for the identification of pharmacologically active compounds for the treatment of specific diseases.
Osteoporosis is a condition characterized by a decrease in bone mass with decreased density and lengthening of bone spaces, producing porosity and fragility. This condition afflicts men and women, particularly menopausal women, of advanced age. This condition is mainly a disorder in the formation of the bone matrix. Osteoblasts, a population of cells that form bone, are typically reduced in number. Osteoblasts are derived from adjacent mesenchymal precursors in a process regulated by factors derived from the local bone. Osteoclasts, a population of cells that break the bone and that are associated with bone resorption, are not reduced in number. The osteoclasts are large, usually multinuclear cells found on the resorbed surfaces of mineralized bone. Osteoclasts are formed by fusion of mononuclear precursors, which originate from precursors born from extra-skeletal blood.
All known and local stimulators of osteoclastic bone resorption, including parathyroid hormone, 1.25D, IL-2, and TNF, modulate their stimulatory effects on the osteoclast through an initial effect on osteoblasts. Osteoblasts are therefore believed to play a major role in the regulation of bone transfer by controlling the rate of new bone formation, as well as serving to generate signals that stimulate osteoclastic bone resorption.
NHR families are associated with the modulation of the proliferation and differentiation of mammalian cells. These cellular processes are controlled by signal molecules that regulate gene expression. NHRs such as retinoid receptors are associated with many diseases and disorders such as osteoporosis, cancer, acne, AIDS, arthritis, psoriasis, lupus erythematosus and the like. The retinoid x receptor (RXR) serves to modulate cellular transcriptional activity thus controlling cell proliferation.
It is recognized in art that osteoblasts play a very complex role in bone formation. It is generally believed that osteoclasts serve to dissolve (resorb) bone such that osteoblasts can then deposit more bone. It is then reasonable that compounds that can inhibit excessive bone resorption or stimulate the proliferation of osteoblasts will be useful for the prevention of bone loss or the stimulation of bone growth.
Takashi et al. (Jopn Kokai Tokyo Koho JP03130216 A2, 4/6/94) exhibits diphenyl compounds having the following general structure where X is -CH2- or -C (= 0) -, for the treatment and prophylaxis of osteoporosis.
Labroo (US 5,389, 646 published on 2/14/95) discloses compounds having the following general structure wherein R1 is H, OH, C1-C17 alkoxy, alkylcarbonyloxy (C1-C17), alkylcarbonylamino (C1-C17) or alkylcarbonyl (C1-C17); R2 is - (CH2) (1.6) -CH2-heterocycle; and R3 is H, OH, C1-C17 alkoxy, (C1-C17) alkylcarbonyl, (C1-C17) alkylcarbonylamino or (C1-C17) alkylcarbonyl, for the treatment and prevention of bone loss.
Other compounds such as the following have been proposed for the treatment of osteoporosis. Even so, these compounds have not found general use due to their limited efficiency. Thus, there remains a need for more effective compounds for the treatment of osteoporosis.
Kamala et al. (Indian J. Chem. (1983), 22B, 1194-96) and Waisser et al. (Collect. Czech, Chem. Commun. (1991), 56. 2978-2985) state the synthesis of and its uses as a synthetic intermediate and antituberculous agent, respectively.
Bis-aromatic compounds are widely known for their use in the treatment of cancer and tumors. In general such compounds effectively inhibit DNA replication thus exerting their cytotoxic effects on mammalian cells. Here too, no compound has been found that is generally applicable for the treatment of a broad spectrum of cancers and tumors. Thus, there still remains a need for more effective anticancer and tumoricide compounds of broader spectrum.
It is an object of the present invention to overcome the limitations inherent in the art of modeling pharmaceutical agents by providing a method for selecting candidate chemical agents that use defined 3-dimensional spatial characteristics. These spatially defined chemical compounds in some aspects overcome more limitations associated with available osteogenic agents by providing agents that stimulate the production of morphogenic bone proteins, and thus provide useful compositions for stimulating osteoblast proliferation and diseases that result in bone loss.
A further objective of the invention is to provide agents that bind other receptors in the nuclear hormone receptor (NHR) family that are associated with diseases.
It is another object of the present invention to provide a method for using particular pharmacologically active compounds for the treatment or prophylaxis of physiological disorders or diseases associated with NHRs such as osteoporosis, arthritis, cancer, tumors and the like.
It is another object of the invention to provide a method for the selection of pharmacologically active compounds that are capable of stimulating the proliferation and differentiation of the osteoblast and are useful for the treatment of physiological disorders associated with NHR and in particular diseases associated with bone loss.
Another objective of the present invention is to provide methods for screening and screening for pharmacologically active compositions which are capable of stimulating the proliferation and differentiation activity of the osteoblast. Such selected composition will be used for the treatment or prophylaxis of osteoporosis and other physiological disorders associated with NHR.

DETAILED DESCRIPTION OF THE INVENTION Method for the Selection of Pharmacologically Active Compounds.
The present invention relates, inter alia, to methods for the selection of a pharmacologically active compound or compounds from a group of compounds. The selected compounds will possess the spatial chemistry structure defined herein, and will have an observable capacity to stimulate the proliferation of the osteoblast or maintain the growth of the osteoblast in culture.
The chemical structure of the selected compound can be defined using the following structural and spatial parameters. The spatial parameters could be obtained by determining the 3-dimensional structure of the selected compounds. Useful methods for the determination of the 3-dimensional structure include: simple crystal x-ray diffraction or 2-dimensional to 3-dimensional algorithmic conversion such as CONCORD or molecular mechanics (MM2). The selected compound will possess two hydrophobic groups exemplified by an aromatic and a carbocyclic group, or alternatively a heterocyclic group. Each of these two hydrophobic groups can be described by means of a centroid, the position of which is simply the average position of all the atoms in the hydrophobic group. For compounds that possess the desired activity, the distance between these two centroids will fall in the range of about 7, or about 7.9 to about 8, or about 8.5 Á. In addition to these two hydrophobic groups, the compounds having the desired activity will possess a chemical grouping or substituent that is capable of forming a hydrogen bond or serving as a Lewis base. One can be formally associated with this hydrogen bond acceptor or Lewis basic site in the molecule, a hydrogen bond donor or Lewis acid group that is external to the molecule. This donor group of the external hydrogen bond or Lewis acid group will be oriented with respect to the molecule in such a way that it makes chemical contact with the complementary site in the molecule.
In this way, the external site will be placed at a distance between 2 and 4? from the complementary site in the molecule, and in such a way that a hydrogen bond or Lewis acid / base associations are formed. A certain geometric relationship must be maintained between the two hydrophobic groups and the donor site of the external hydrogen bond / Lewis acid. This geometric relationship can be described in terms of distances and angles. The external site will be arranged asymmetrically with respect to the two hydrophobic groups, such that one hydrophobic group (the distal hydrophobic group) moves farther from the external site than the other hydrophobic group (proximal). For compounds possessing the desired activity, the distance between the external hydrogen bond donor / Lewis acid group and the centroid describing the distal hydrophobic group will fall within the range of about 6, or about 6.7 to about 7, or about 7.7 Á and will fall optimally within the range of about 6, or about 6.8 to about 7, or about 7.7 Á. For compounds possessing the desired activity, the distance between this external site and the centroid that describes the proximal hydrophobic site will fall within the range of about 4, or about 4.6, to about 6, or about 6.3, Á, and will be optimally within the range from about 4, or about 4.9, to about 6.0 Á. In addition to the groups already described, the compounds possessing the desired activity will also possess a second group capable of serving as a hydrogen bond donor or as a Lewis base.
An angle can be used to describe the orientation with respect to this second acceptor site of the hydrogen / Lewis base link in the molecule. This angle is formed between the centroid that describes the distal hydrophobic group, this second hydrogen bond acceptor group and the external donor hydrogen / Lewis acid donor group. For compounds that possess the desired activity, this angle will fall within the range of 74 to 112 degrees, and will be optimally within the range of 85 to 89 degrees.
The spatial definition of some embodiments of the compound of formula II can be further understood by Figures 2 and 3 which are representations of a space filling model of the central rings in Y and the group of the compound of formula II. Observe the positioning and filling of the space of each of W, L and Y as represented by the white regions. The shaded regions indicate hydrogen bond acceptor regions found within or near the vicinity of L. For the purpose of simplification, substituents that could be attached from the central rings in and Y are not shown. The 3-dimensional structure shown requires a compound that possesses the pharmacological activities recited herein. It should be understood that the compounds contemplated and encompassed by the scope herein can be adapted to other conformations that could produce pharmacological activity. Such conformations could involve link distortions, link angle distortions, spatial variations in size, variations in group spatial orientation and the like and are within the scope of the present invention.
In one embodiment, the selected compound will possess osteoblast proliferation stimulating activity and / or be able to maintain or increase the growth of the osteoblast in vi tro. Such an activity could be determined using any of a number of methods known to the person skilled in the art, such as using the luciferase promoter test described in Example 1. In that assay, a compound possessing the ability to stimulate proliferation or growth of the osteoblast will stimulate the luciferase activity. Since the BMP-2 luciferase promoter constructs were transfected into immortalized murine osteoblasts (2T3 cells), the stimulation of the luciferase activity reasonably correlates to a stimulation activity of the osteoblast proliferation as recognized by those skilled in the art. art.
This method contemplates compounds having an osteoblast proliferation stimulating activity at least about that of the reference compound 2- (4-methoxybenzoylamino) -1,3-benzothiazole. By the phrase "at least about" is meant an activity of not less than about 100X of the activity of the reference compound and preferably an activity at least equal to or greater than that of the reference compound as determined by the ED50 in the test of promoter. Under the conditions of the test of Example 1, the reference compound has an ED50 of about 0.1 micromolar; therefore, the compounds selected by this method should have an ED50 of no greater than 10 micromolar.
Method to Stimulate Bone Growth The present invention in one aspect provides a method directed to the use of compounds of formulas II and III for the stimulation of osteoblast proliferation. It is projected that these compounds will possess the ability to stimulate osteoblast proliferation and therefore bone growth.
This method could be practiced in vivo or in vi tro. When in vivo, it is contemplated that all vertebrate animals, particularly those suffering from osteoporosis, will exhibit at least some stimulation of osteoblast proliferation when treated with compounds of formula II or III.
When practicing in vitro, it is contemplated that the compounds of formula II or III could be tested by any number of techniques known to the person skilled in the art to determine the stimulation activity of the osteoblast proliferation. Such a technique is described as the osteoblast proliferation test of Example 1.
Without being bound by the mechanism, it is believed that the compounds of formula II or III exert their bone growth stimulation activity by stimulating osteoblast proliferation which is a result of the ability of the compounds to modulate cellular transcription by binding to one. or more different types of NHR.
The evidence that these compounds of formulas II and III possess the ability to bind NHRs could be obtained using the test described in Example 6. In that test, a compound is tested for its ability to displace tritiated retinoic acid (RA). of a retinoid receptor. The displaced RA is quantified by scintillation. Figure 1 shows the results obtained when a compound displaces RA. Compounds that possess the ability to displace RA from the retinoic acid receptors can be used to treat or prevent disorders or diseases associated with the receptors.

Unless otherwise indicated, all chemicals were purchased from Aldrich Chemicals (Milwaukee, Wl); EXEMPJ.Q 1 TECHNIQUE TO IDENTIFY CHEMICAL COMPOUNDS OUE STIMULATE OSEO GROWTH This technique has been described in the scientific literature [Ghosh-Choudhury, N .; Windle, J; J .; Koop, B. A .; Harris, M.A .; Guerrero, D. L .; Wozney, J. M .; Mundy, G. R .; Harris, S. E .; "Immortalized Murine Osteoblasts Derived from BMP 2-T-Antigen Expressing Transgenic Mice" Endocrinologv (1996) 137. 331-339]. These techniques are specifically incorporated herein by reference. This method could be used only to identify or select a library of candidate compounds with pharmacological activity to promote, stimulate or maintain osteoblast growth, or in conjunction with the technique provided to select spatially defined molecules and candidate substances that have proliferative activity of osteoblast.
Immortalized murine osteoblasts (2T3 cells) containing a promoter fragment of bone morphogenetic protein 2 (BMP-2) are isolated from the bald of transgenic mice and cloned. These 2T3 cells are reclonable and can be stably transfected with luciferase constructs of the BMP-2 promoter. The activity of the BMP-2 promoter can then be stimulated by recombinant human BMP-2 (rhBMP-2) or chemical compounds that stimulate osteoblast proliferation. Using this BMP-2 promoter test as an additional screening technique, the ED50 of the compounds that stimulate luciferase activity can also be tested, and, by implication, the proliferation of osteoblast. Other in vitro cellular tests for testing the activity of screened and selected candidate compounds well known to those of ordinary skill in the art could be used in place of the promoter test described above and provide additional measurement of the pharmacological activity of the compound that stimulates proliferation. of osteoblast. For example, a culture of osteoblast cells could be used. 2T3 cells in 10 cm tissue culture plastic plates are stably transfected with 10 micrograms of the plasmid containing the luciferase reporter gene driven by -2736/114 bp of the BMP-2 promoter and 12 micrograms of the plasmid pSV2neo for selection of the clone resistant to G418.
The transfection is carried out by the calcium phosphate precipitation technique. Stable clonal cell lines are generated using MEM containing 7% FCS and 200 microgram / mL G418. The activity of the luciferase enzyme can be measured in 15 different clonal cell lines. A cell line (2T3-BMP-2-LUC) is chosen here because using this test for luciferase has shown little variability over 20 steps. For a control group, a stable cytoponal cell line (2T3-basic LUC) is established as above, using the non-promoted luciferase vector, pGL2basic (Promega Corp., Madison, Wl) in place of the BMP-promoter luciferase plasmid 2. Both cell lines are plated on 35 mm tissue culture plates and treated with 0, 2, 5, 10 and 20 nanograms / mL of rhBMP-2 for 48 hr in MEM containing 2% FCS. Each concentration of rhBMP-2 is used in triplicate and each experiment is repeated three times. Luciferase activity is measured using a Promega kit and a luminometer.
E.JP_PtQ 2 PRODUCTION OF MULTI-GRAM AMOUNTS OF 2- (2- METOXYBENZOYLAMINO) BENZTIAZOL The present group of examples establishes a method wherein the benzthiozole compounds could be obtained. However, other methods could be used in the practice of the present invention. A solution of 4.5 g of 2-aminobenzthiazole in 40 mL of dichloromethane and 10 mL of pyridine was cooled in an ice bath. To this cooled solution was slowly added a solution of 2-methoxy benzoyl chloride in 10 mL of dichloromethane. The resulting mixture was stirred for 3 hours while the ice bath was slowly heated to room temperature. The reaction mixture was diluted with 200 mL of ethyl acetate and washed with IN HCl (2 x 50 mL), saturated NaHCO 3 (1 x 40 mL) and saturated NaCl (1 x 50 mL). After drying with Na 2 SO 4, the solution containing the crude product was filtered and evaporated to dryness.
