1. Technical Field
The present invention relates to a therapeutic agent for diseases in which corticotropin releasing factor (CRF) is considered to be involved, such as depression, anxiety, Alzheimer's disease, Parkinson's disease, Huntington's chorea, eating disorder, hypertension, gastral diseases, drug dependence, cerebral infarction, cerebral ischemia, cerebral edema, cephalic external wound, inflammation immunity-related diseases, alpecia, irritable bowel syndrome, sleep disorders, epilepsy, dermatitides, schizophrenia, etc.
2. Description of the Prior Art
CRF is a hormone comprising 41 amino acids (Science, 213, 1394-1397, 1981; and J. Neurosci., 7, 88-100, 1987), and it is suggested that CRF plays a core role in biological reactions against stresses (Cell. Mol. Neurobiol., 14, 579-588, 1994; Endocrinol., 132, 723-728, 1994; and Neuroendocrinol. 61, 445-452, 1995). For CRF, there are the following two paths: a path by which CRF acts on peripheral immune system or sympathetic nervous system through hypothalamus-pituitary-adrenal system, and a path by which CRF functions as a neurotransmitter in central nervous system (in Corticotropin Releasing Factor: Basic and Clinical Studies of a Neuropeptide, pp. 29-52, 1990). Intraventricular administration of CRF to hypophysectomized rats and normal rats causes an anxiety-like symptom in both types of rats (Pharmacol. Rev., 43, 425-473, 1991; and Brain Res. Rev., 15, 71-100, 1990). That is, there are suggested the participation of CRF in hypothalamus-pituitary-adrenal system and the pathway by which CRF functions as a neurotransmitter in central nervous system.
The review by Owens and Nemeroff in 1991 summarizes diseases in which CRF is involved (Pharmacol. Rev., 43, 425-474, 1991). That is, CRF is involved in depression, anxiety, Alzheimer's disease, Parkinson's disease, Huntington's chorea, eating disorder, hypertension, gastrointestinal diseases, drug dependence, inflammation, immunity-related diseases, etc. It has recently been reported that CRF is involved also in epilepsy, cerebral infarction, cerebral ischemia, cerebral edema, and cephalic external wound (Brain Res. 545, 339-342, 1991; Ann. Neurol. 31, 48-498, 1992; Dev. Brain Res. 91, 245-251, 1996; and Brain Res. 744, 166-170, 1997). Accordingly, antagonists against CRF receptors are useful as therapeutic agents for the diseases described above.
WO02/002549 and WO0/053604 disclose pyrrolopyridine and pyrrolopyrimidine derivatives respectively as CRF receptor antagonists. Bioorganic & Medicinal Chemistry 10 (2002) 175-183 also discloses pyrrolopyrimidine derivatives. However, none disclose the compounds provided in the present invention.
An object of the present invention is to provide an antagonist against CRF receptors which is effective as a therapeutic or prophylactic agent for diseases in which CRF is considered to be involved, such as depression, anxiety, Alzheimer's disease, Parkinson's disease, Huntington's chorea, eating disorder, hypertension, gastral diseases, drug dependence, epilepsy, cerebral infarction, cerebral ischemia, cerebral edema, cephalic external wound, inflammation, immunity-related diseases, alpecia, irritable bowel syndrome, sleep disorders, epilepsy, dermatitides, schizophrenia, etc.

Monkey amygdala membranes were used as a receptor preparation.
125I-CRF was used as 125I-labeled ligand.
Binding reaction using the 125I -labeled ligand was carried out by the following method described in The Journal of Neuroscience, 7, 88 (1987).
Preparation of Receptor Membranes:
Monkey amygdala was homogenized in 50 mM Tris-HCl buffer (pH 7.0) containing 10 mM MgCl2, 2 mM EDTA and centrifuged at 48,000×g for 20 min, and the precipitate was washed once with Tris-HCl buffer. The washed precipitate was suspended in 50 mM Tris-HCl buffer (pH 7.0) containing 10 mM MgCl2, 2 mM EDTA, 0.1% bovine serum albumin and 100 kallikrein units/ml aprotinin, to obtain a membrane preparation.
CRF Receptor Binding Test:
The membrane preparation (0.3 mg protein/ml), 125I-CRF (0.2 nM) and a test drug were reacted at 25° C. for 2 hours. After completion of the reaction, the reaction mixture was filtered by suction through a glass filter (GF/C) treated with 0.3% polyethylene imine, and the glass filter was washed three times with phosphate-buffered saline containing 0.01% Triton X-100. After the washing, the radioactivity of the filter paper was measured in a gamma counter.
The amount of 125I-CRF bound when the reaction was carried out in the presence of 1 μM CRF was taken as the degree of nonspecific binding of 125I -CRF, and the difference between the total degree of 125I -CRF binding and the degree of nonspecific 125I -CRF binding was taken as the degree of specific 125I -CRF binding. An inhibition curve was obtained by reacting a definite concentration (0.2 nM) of 125I-CRF with various concentrations of each test drug under the conditions described above. A concentration of the test drug at which binding of 125I -CRF is inhibited by 50% (IC50) was determined from the inhibition curve.
As a result, it was found that compounds 1-003, 1-004, 1-005, 1-007, 1-008, 1-009, 1-010, 1-013, 1-014, 1-016, 1-018, 1-019, 1-021, 1-032, 1-038, 1-039, 1-040, 1-046, 1-050, 1-051, 1-052, 1-053, 1-054, 1-056, 1-057, 1-058, 1-059, 1-060, 1-061, 1-062, 1-063, 1-064, 1-067, 1-068, 1-072, 1-073, 1-074, 1-077, 1-078, 1-087, 1-088, 1-089, 1-090, 1-091, 1-097, 1-098, 1-099, 1-103, 1-104, 1-105, 1-112, 1-117, 1-118, 1-120, 1-121, 1-122, 1-123, 1-125, 1-126, 1-127, 1-128, 1-129, 1-130, 1-131, 1-132, 1-133, 1-135, 1-141, 1-142, 1-143, 1-144, 1-145, 1-148, 1-149, 1-150, 1-151, 1-152, 1-153, 1-154, 1-155, 1-156, 1-157, 1-158, 1-159, 1-160, 1-161, 1-162, 1-163, 1-164, 1-165, 1-166, 1-167, 1-172, 1-173, 1-176, 1-177, 1-178, 1-179, 1-181, 1-183, 1-184, 1-188, 1-195, 1-208, 1-213, 1-235, 1-236, 1-237, 1-243, 1-245, 1-251, 1-257, 1-262, 1-264, 1-278, 1-280, 1-283, 1-284, 1-285, 1-286, 1-287, 1-288, 1-302, 1-304, 1-306, 1-308, 1-319, 1-320, 1-332, 1-333, 1-336, 1-337, 2-002, 2-003, 2-004, 2-005, 2-006, 2-007, 2-008, 2-009, 2-010, 2-011, 2-012, 2-013, 2-014, 2-015, 2-016, 2-017, 2-018, 2-019, 2-020, 2-021, 2-022, 2-023, 2-024, 2-025, 2-026, 2-027, 2-028, 2-029, 2-030, 2-031, 2-032, 2-033, 2-034, 2-035, 2-036, 2-037, 2-038, 2-039, 2-040, 2-041, 2-042, 2-043, 2-044, 2-045, 2-046, 2-047, 2-048, 2-049, 2-050, 2-052, 2-053, 2-054, 2-055, 2-056, 2-057, 2-058, 2-059, 2-060, 2-061, 2-062, 2-063, 2-064, 2-065, 2-066, 2-068, 2-069, 2-070, 2-071, 2-072, 2-073, 2-074, 2-075, 2-076, 2-077, 2-078, 2-079, 2-080, 2-081, 2-082, 2-084, 2-087, 2-088, 2-089, 2-090, 2-091, 2-092, 2-093, 2-094, 2-095, 2-096, 2-097, 2-098, 2-099, 2-100, 2-101, 2-102, 2-103, 2-104, 2-105, 2-106, 2-107, 2-108, 2-109, 2-110, 2-111, 2-112, 2-113, 2-114, 2-115, 2-116, 2-117, 2-118, 2-119, 2-120, 2-121, 2-122, 2-123, 2-124, 2-125, 2-126, 2-127, 2-128, 3-001, 3-004, 3-006, 3-007, 3-008, 3-009, 3-015 and 3-018 can be exemplified as typical compounds having an IC50 value of 50 nM or less.
