The present invention relates to heterocyclic compounds represented by the formula I
wherein X represents nitrogen atom or CH; R1 represents halogen atom or hydroxyl; R2 represents hydrogen atom, hydroxyl or amino; R3 represents morpholino (which may be substituted with one or two C1-C6 alkyl), pyrrolidinyl (which may be substituted with hydroxy C1-C6 alkyl) or NR6R7 [R6 represents C1-C6 alkyl and R7 represents piperidinyl (which may be substituted with C1-C6 alkyl)]; R4 and R5 each represents hydrogen atom or C1-C6 alkyl, with the proviso that R2 is hydrogen atom and R3 is pyrrolidinyl (which may be substituted with hydroxy C1-C6 alkyl) when R1 is hydroxyl
本发明涉及式 I 所代表的杂环化合物
其中X代表氮原子或CH;R1代表卤原子或羟基;R2代表氢原子、羟基或氨基;R3代表吗啉基(可被一个或两个C1-C6烷基取代)、吡咯烷基(可被羟基C1-C6烷基取代)或NR6R7[R6代表C1-C6烷基,R7代表哌啶基(可被C1-C6烷基取代)];R4 和 R5 各自代表氢原子或 C1-C6 烷基,但 R1 为羟基时,R2 为氢原子,R3 为吡咯烷基(可被羟基 C1-C6 烷基取代)。
