The present invention provides 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. The compounds are represented by general formula (I):
wherein V represents an oxygen atom or a sulfur atom;
W represents 1,4-piperazinediyl or 1,4-homopiperazinediyl in which carbons on the ring may be substituted by unsubstituted alkyl groups;
X represents a nitrogen atom or C-R9;
Y represents a nitrogen atom or C-R8;
Z represents a nitrogen atom or C-R7 (provided that at least one of X, Y and Z represents a nitrogen atom);
R1 represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alicyclic alkyl group, etc.;
R2 represents a substituted alkyl group, a substituted or unsubstituted alicyclic alkyl group, etc.;
R3, R4, R5 and R6, which may be the same or different, each represents a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a nitro group, a cyano group, - OR12, -NR15R16, etc.;
R7 represents a halogen atom, etc.;
R8 has the same significance as R7, and
R9 represents a hydrogen atom or -COR41.
本发明提供了含氮杂环化合物及其药学上可接受的盐类,它们能抑制 PDGF 受体的磷酸化,从而阻碍细胞的异常生长和游走,因此可用于预防或治疗细胞增殖性疾病,如动脉硬化、血管再阻塞、癌症和肾小球硬化症。这些化合物由通式 (I) 表示:
其中 V 代表氧原子或硫原子;
W 代表 1,4-哌嗪二基或 1,4-高哌嗪二基,其中环上的碳可被未取代的烷基取代;
X 代表氮原子或 C-R9;
Y 代表氮原子或 C-R8
Z 代表氮原子或 C-R7(条件是 X、Y 和 Z 中至少有一个代表氮原子);
R1 代表氢原子、取代或未取代的烷基、取代或未取代的脂环烷基等;
R2 代表取代的烷基、取代或未取代的脂环烷基等;
R3、R4、R5 和 R6 可以相同或不同,各自代表氢原子、卤素原子、取代或未取代的烷基、硝基、氰基、- OR12、-NR15R16 等;
R7 代表卤素原子等;
R8 与 R7 意义相同,以及
R9 代表氢原子或-COR41。
