AZOLO TRIAZINES AND PYRIMIDINES

FIELD OF THE INVENTION

= This invention zelates a treatment of psychiatric disorders and neurological diseases inr-luding major depression, anxiety-related disorders, post-traumatic stress disorder, supranuclear palsy and feeding disorders as well as treatment of immunological, cardiovascular or heart-related diseases and colonic hypersensitivity associated with psychopathological disturbance and . 15 stress, by administration of certain [1,5-a]-pyrazolo-1,3,5-triazines, (1,5-a]-1,2,3-triazolo-1,3,5-triazines, (1,5-a]-pyrazolo-pyrimidines and [1,5-a]-1,2,3-triazolo-pyrimidines.

BACKGROUND OF THE INVENTION
Corticotropin releasing factor (herein referred to as CRF), a 41 amino acid peptide, is the primary physiological regulator of proopiomelanocortin(POMC) -derived peptide secretion from the anterior pituitary gland (J. Rivier et al., Proc. Nat. Acad.
= Sci. (USA) 80:4851 (1983); W. Vale et al., Science 213:1394 (1981)]. In addition to its endocrine role at the pituitary gland, immunohistochemical localization of CRF has demonstrated that the hormone has a broad extrahypothalamic distribution in the central nervous system and produces a wide spectrum of autonomic, electrophysiological and behavioral effects consistent with a neurotransmitter or neuromodulator role in brain (W. Vale et al., Rec.
Prog. Horm. Res. 39:245 (1983); G.F. Koob, Persp.
Behav. Med. 2:39 (1985); E.B. De Souza et al., J.

~ .

Neurosci. 5:3189 (1985)). There is also evidence that CRF plays a significant role in integrating the response of the immune system to physiological, psychological, and immunological stressors [J.E.
Blalock, Physiological Reviews 69:1 (1989); J.E.
Morley, Life Sci. 41 : 527 (1987)).
Clinical data provide evidence that CRF has a role in psychiatric disorders and neurological diseases including depression, anxiety-related disorders and feeding disorders. A role for CRF has also been postulated in the etiology and pathophysiology of Alzheimer's disease, Parkinson's disease, Huntington's disease, progressive supranuclear palsy and amyotrophic lateral sclerosis as they relate to the dysfunction of CRF neurons in =
the central nervous system [for review see E.B. De Souza, Hosp. Practice 23:59 (1988)].
In affective disorder, or major depression, the concentration of CRF is significantly increased in the cerebral spinal fluid (CSF) of drug-free individuals [C.B. Nemeroff et al., Science 226:1342 (1984); C.M. Banki et al., Am. J. Psychiatry 144:873 (1987); R.D. France et al., Biol. Psychiatry 28:86 (1988); M. Arato et al., Bio1 Psychiatry 25:355 (1989)]. Furthermore, the density of CRF receptors is significantly decreased in the frontal cortex of =
suicide victims, consistent with a hypersecretion of CRF [C.B. Nemeroff et al., Arch. Gen. Psychiatry 45:577 (1988)]. In addition, there is a blunted adrenocorticotropin (ACTH) response to CRF (i.v.
administered) observed in depressed patients [P.W.
Gold et al., Am J. Psychiatry 141:619 (1984); F.
Holsboer et al., Psychoneuroendocrinology 9:147 (1984); P.W. Gold et al., New Eng. J. Med. 314:1129 (1986)]. Preclinical studies in rats and non-human primates provide additional support for the

-2-_..

= WO 98/03510 PCT/US97/13072 hypothesis that hypersecretion of CRF may be involved in the symptoms seen in human depression [R.M.
Sapolsky, Arch. Gen. Psychiatry 46:1047 (1989)].
There is preliminary evidence that tricyclic antidepressants can alter CRF levels and thus modulate the numbers of CRF receptors in brain [Grigoriadis et al., Nevropsychopharmacology 2:53 (1989) ] =
There has also been a role postulated for CRF in the etiology of anxiety-related disorders. CRF
produces anxiogenic effects in animals and interactions between benzodiazepine / non-benzodiazepine anxiolytics and CRF have been demonstrated in a variety of behavioral anxiety models [D.R. Britton et al., Life Sci. 31:363 (1982);
= C.W. Berridge and A.J. Dunn Regul. Peptides 16:83 (1986)). Preliminary studies using the putative CRF
receptor antagonist a-helical ovine CRF (9-41) in a variety of behavioral paradigms demonstrate that the antagonist produces "anxiolytic-like" effects that are qualitatively similar to the benzodiazepines (C.W. Berridge and A.J. Dunn Horm. Behav. 21:393 (1987), Brain Research Reviews 15:71 (1990)].
Neurochemical, endocrine and receptor binding studies have all demonstrated interactions between CRF and benzodiazepine anxiolytics providing further evidence = for the involvement of CRF in these disorders.
Chlordiazepoxide attenuates the "anxiogenic" effects of CRF in both the conflict test (K.T. Britton et al., Psychopharmacology 86:170 (1985); K.T. Britton et al., Psychopharmacology 94:306 (1988)] and in the acoustic startle test [N.R. Swerdlow et al., Psychopharmacology 88:147 (1986)] in rats. The benzodiazepine receptor antagonist (Ro15-1788), which was without behavioral activity alone in the operant conflict test, reversed the effects of CRF in a dose-

-3-dependent manner while the benzodia2epine inverse agonist (FG7142) enhanced the actions of CRF (K.T.
Britton et al., Psychopharmacology 94:306 (1988)).
The mechanisms and sites of action through which the standard anxiolytics and antidepressants produce their therapeutic effects remain to be elucidated.
It has been hypothesized however, that they are involved in the suppression of the CRF hypersecretion tha: is observed in these disorders. Of particular interest is that preliminary studies examining the effects of a CRF receptor antagonist (a - h elical CRF9-41) in a variety of behavioral -paradigms have demonstrated that the CRF antagonist produces "anxiolytic-like" effects qualitatively similar to the ber.zodiazepines [for review see G.F. Koob and K.T. Britton, in: Corticotropin-Releasing Factor:
Basic and Clinical Studies of a Neuropeptide, E.B. De Souza and C.B. Nemeroff eds., CRC Press p221 (1990)].
Several publications describe corticotropin releasing factor antagonist compounds and their use to treat psychiatric disorders and neurological diseases. Examples of such publications include DuPont Merck PCT application WO 95/10506, Pfizer WO
95/33750, Pfizer PtO 95/34563, Pfizer WO 95/33727 and Pfizer EP 0778 277 A1, Insofar as is known, (1,5-a)-pyrazolo-1,3,5-triazines, (1,5-a)-1,2,3-triazolo-1,3,5-triazines, (1,5-a)-pyrazolo-pyrimidines and (1,5-a)-1,2,3-triazolo-pyrirnidines, have not been previously reported as corticotropin releasing factor antagonist compounds useful in the treatment of psychiatric disorders and neurological diseases. However, there have been publications which teach some of these compounds for other uses.

The cc.ditions for these transformations are the same as those employed for the conversions of compound of Formula (4) to compound of Formula (7) in Scheme 4.
Alternatively, compounds of Formula (25), where A
is CR, may be reacted with compounds of the formula R1(C=0)CHR(C=Y)ORc (where R1 and R are defined as above and Rc is a lower alkyl group) to give a compound of =

Utilitv CRF-R1 Receptor Binding Assay for the Evaluation of Biological Activity The following is a description of the isolation of cell membranes containing cloned human CRF-R1 receptors for use in the standard binding assay as =
well as a description of the assay itself.
Messenger RNA was isolated from human hippocampus.
The mRNA was reverse transcribed using oligo (dt) 12-18 and the-coding region was amplified by PCR from start to stop codons The resulting PCR fragment was cloned into the EcoRV site of pGEMV, from whence the insert was reclaimed using XhoI + XbaI and cloned into the XhoI +
XbaI sites of vector pm3ar ( which contains a CMV
promoter, the SV40 't' splice and early poly A signals, an Epstein-Barr viral origin of replication, and a hygromycin selectable marker). The resulting expression vector, called phchCRFR was transfected in 293EBNA cells and cells retaining the episome were selected in the presence of 400 M hygromycin. Cells surviving 4 weeks of selection in hygromycin were pooled, adapted to growth in suspension and used to generate membranes for the binding assay described below. Individual aliquots containing approximately 1 x 108 of the suspended cells were then centrifuged to form a pellet and frozen.
For the binding assay a frozen pellet described above containing 293EBNA cells transfected with hCRFR1 receptors is homogenized in 10 ml of ice cold tissue buffer ( 50 mM HEPES buffer pH 7.0, containing 10 mM
MgC12, 2 mM EGTA, 1 4g/1 aprotinin, 1 g/ml leupeptin = 15 and 1 g/ml pepstatin). The homogenate is centrifuged at 40,000 x g for 12 min and the resulting pellet rehomogenized in 10 ml of tissue buffer. After another centrifugation at 40,000=x g for 12 min, the pellet is resuspended to a protein concentration of 360 g/ml to be used in the assay.
Binding assays are performed in 96 well plates;
each well having a 300 l capacity. To each well is added 50 l of test drug dilutions (final concentration of drugs range from 10-10 - 10-5 M), 100 }ll of 125I-ovine-CRF (1251-o-CRF) (final concentration 150 pM) and = 150 l of the cell homogenate described above. Plates are then allowed to incubate at room temperature for 2 hours before filtering the incubate over GF/F filters (presoaked with 0.3% polyethyleneimine) using an appropriate cell harvester. Filters are rinsed 2 times with ice cold assay buffer before removing individual filters and assessing them for radioactivity on a gamma counter.
Curves of the inhibition of 125I-o-CRF binding to cell membranes at various dilutions of test drug are analyzed by the iterative curve fitting program LIGAND

[P.J. Munson and D. Rodbard, Anal. Biochern. 107:220 (1980), which provides Ki values for inhibition which are then used to assess biological activity.
A compound is considered to be active if it has a Ki value of less than about 10000 nM for the inhibition of CRF.

Inhibition of CRF-Stimulated Adenyla P yclaSe Activity Inhibition of CRF-stimulated.adenylate cyclase activity can be performed as described by G.
Battaglia et al. Synapse 1:572 (1987). Briefly, assays are carried out at 37 C for 10 min in 200 ml of buffer containing 100 mM Tris-HC1 (pH 7.4 at 37 C), 10 mM MgC12, 0.4 mM EGTA, 0.1% BSA, 1 mM
isobutylmethylxanthine (IBMX), 250 units/ml phosphocreatine kinase, 5 mM creatine phosphate, 100 mM guanosine 5'-triphosphate, 100 nM oCRF, antagonist peptides (concentration range 10-9 to 10-6m) and 0.8 mg original wet weight tissue (approximately 40-60 mg protein). Reactions are initiated by the addition of 1 mM ATP/32PJATP (approximately 2-4 mCi/tube) and terminated by the addition of 100 ml of 50 mM Tris-HCL, 45 mM ATP and 2% sodium dodecyl sulfate. In order to monitor the recovery of cAMP, 1 l of [3H]cAMP (approximately 40,000 dpm) is added to each =
tube prior to separation. The separation of [32P]cAMP from [32P]ATP is performed by sequential elution over Dowex and alumina columns.
