ABSTRACT:
TECHNICAL FIELD
The present invention relates to nitrogen-containing heterocyclic compounds and pharmaceutically acceptable salts thereof which have inhibitory activity on phosphorylation of platelet-derived growth factor (PDGF) receptor and are useful for the treatment of cell-proliferative diseases such as arteriosclerosis, vascular reobstruction, cancer and glomerulosclerosis.
BACKGROUND ART
PDGF is known to act as an aggravating factor for cell-proliferative diseases such as arteriosclerosis, vascular reobstruction after percutaneous coronary angioplasty and bypass operation, cancer, glomerulonephritis, glomerulosclerosis, psoriasis and articular rheumatism [Cell, 46, 155-169 (1986); Science, 253, 1129-1132 (1991); Nippon Rinsho (Japanese J. of Clinical Medicine), 50, 3038-3045 (1992); Nephrol Dial Transplant, 10, 787-795 (1995); Kidney International, 43 (Suppl. 39), S86-S89 (1993); Journal of Rheumatology, 21, 1507-1511 (1994); Scandinavian Journal of Immunology, 27, 285-294 (1988), etc.].
As for quinazoline derivatives which are useful as drugs, N,N-dimethyl-4-(6,7-dimethoxy-4-quinazolinyl)-1-piperazine carboxamide is described as a bronchodilator in South African Patent No. 67 06512 (1968). Dimethoxyquinazoline derivatives are described as inhibitors of phosphorylation of epidermal growth factor (EGF) receptor in Japanese Published Unexamined Patent Application No. 208911/93 and WO 96/09294. Quinoline derivatives having benzodiazepine receptor agonist activity are described in Pharmacology Biochemistry and Behavior, 53, 87-97 (1996) and European Journal of Medicinal Chemistry, 31, 417-425 (1996), and quinoline derivatives which are useful as anti-parasite agents are described in Indian Journal of Chemistry, 26B, 550-555 (1987).
Inhibitors of phosphorylation of PDGF receptor so far known include bismono- and bicyclic aryl compounds and heteroaryl compounds (WO 92/20642), quinoxaline derivatives [Cancer Research, 54, 6106-6114 (1994)], pyrimidine derivatives (Japanese Published Unexamined Patent Application No. 87834/94) and dimethoxyquinoline derivatives [Abstracts of the 116th Annual Meeting of the Pharmaceutical Society of Japan (Kanazawa) (1996), 2, p. 275, 29(C2) 15-2].
DISCLOSURE OF THE INVENTION
An object of the present invention is to provide nitrogen-containing heterocyclic compounds and pharmaceutically acceptable salts thereof which inhibit phosphorylation of PDGF receptor to hinder abnormal cell growth and cell wandering and thus are useful for the prevention or treatment of cell-proliferative diseases such as arteriosclerosis, vascular reobstruction, cancer and glomerulosclerosis.
