A compound of formula (I) or a pharmaceutically acceptable salt thereof:
in which one of X and Y represents hydrogen and the other represents Z, where Z is a group
in which Q represents a 3-membered divalent residue completing a 5-membered aromatic ring and comprises zero, one or two nitrogen atoms, Q being optionally C-substituted by a group R1 selected from halogen, CN, OR2, SR2, N(R2)2, NHCOR2, NHCOOCH3, NHCOOC2H5, NHOR2, N3, NHNH2, N02, COR2, COR3, C2-4 alkenyl, C2-4 alkynyl, cyclopropyl or C1-2 alkyl optionally substituted with OR2, N(R2)2, SR2, C02R2, CON(R2)2 or one, two or three halogen atoms, in which each R2 is independently hydrogen or C1-2 alkyl and R3 is OR2, NH2 or NHR2; r represents an integer of 2 or 3, s represents an integer of 1 or 2 and t represents 0 or 1; Ra and Rb each represent hydrogen or, when X is hydrogen, optionally together represent a bond; with the proviso that when Y is hydrogen s is 1.
式 (I) 的化合物或其药学上可接受的盐:
其中 X 和 Y 的一个代表氢,另一个代表 Z,其中 Z 是一个基团
其中 Q 代表完成 5 元芳香环的 3 元二价残基,包含 0、1 或 2 个氮原子,Q 任选被选自卤素、CN、OR2、SR2、N(R2)2、NHCOR2、NHCOOCH3、NHCOOC2H5、NHOR2、N3、NHNH2、N02、COR2、COR3、C2-4 烯基、C2-4 炔基、环丙基或任选被 OR2、N(R2)2、SR2、C02R2、CON(R2)2 或一个、两个或三个卤素原子取代的 C1-2 烷基,其中每个 R2 独立为氢或 C1-2 烷基,R3 为 OR2、NH2 或 NHR2;r 代表 2 或 3 的整数,s 代表 1 或 2 的整数,t 代表 0 或 1;Ra 和 Rb 各自代表氢,或当 X 为氢时,可选择共同代表一个键;但当 Y 为氢时,s 为 1。
