The present invention provides a condensed pyrimidine compound represented by formula (I) or pharmaceutically acceptable salt thereof:
where A represents a ring
where at least one carbon atom within said ring is optionally substituted with one or more groups selected from the group consisting of lower alkyl, —O-(lower alkyl), halogen atom, carboxyl, —CO2-(lower alkyl), and carbamoyl, R1 represents: (1) phenyl substituted with at least three halogen atoms, which may have at least one additional substituent, or (2) cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, or cycloheptyl, each of which is optionally substituted; and R2 represents a group represented by formula (II) or an optionally substituted cyclic amino:
wherein R21 and R22 may be identical or different and each represents —H, lower alkyl, lower alkenyl, lower alkynyl, cycloalkyl, phenyl, heteroaryl, non-aromatic heterocyclyl, or —O-(lower alkyl), each of which is optionally substituted.
本发明提供一种由式(I)表示的缩合嘧啶化合物或其药学上可接受的盐:
其中A代表一个环,该环内至少有一个碳原子可选择地被选自下列群组的一个或多个基团取代:较低的烷基,—O-(较低的烷基),卤素原子,羧基,—CO2-(较低的烷基)和氨基甲酰基。R1表示:(1)苯基,该苯基被至少三个卤素原子取代,可能具有至少一个额外的取代基,或(2)环丙基,环丁基,环戊基,环己基或环庚基,每个基团可选择地被取代;R2表示由式(II)表示的基团或可选择地取代的环状氨基:
其中R21和R22可以相同也可以不同,每个都表示—H,较低的烷基,较低的烯基,较低的炔基,环烷基,苯基,杂环芳烃,非芳香族杂环基或—O-(较低的烷基),每个基团可选择地被取代。
