A compound of formula (I) or a pharmaceutically acceptable salt thereof:
in which Z is a heterocyclic group
in which Q represents a 3-membered divalent residue completing a 5-membered aromatic ring and comprises one or two heteroatoms selected from oxygen, nitrogen and sulphur, or three nitrogen atoms, any amino nitrogen being substituted by a C1 -2 alkyl, cyclopropyl or propargyl group, and any ring carbon atom being optionally substituted by a group R1 ; or a group
in which A1 , A2 and A3 complete a 5-membered aromatic ring and A1 is oxygen or sulphur, one of A2 and A3 is CR2 and the other is nitrogen or CR3, or A2 is oxygen or sulphur, one of A1 and A3 is CR2 and the other is CR3; and R1, R2 and R3 are independently selected from hydrogen, halogen, CN, OR4, SR4, N(R4)2, NHCOR4, NHCOOCH3, NHCOOC2H5, NHOR4, NHNH2, N02, COR4, COR5, cyclopropyl, C2-5 straight chain alkenyl, C2-5 straight chain alkynyl or C1-5 straight chain alkyl optionally terminally substituted with OR4, N(R4)2, SR4, C02R4, CON(R4)2 or one, two or three halogen atoms, in which each R4 is independently hydrogen or C1-3 alkyl and R5 is OR4, NH2 or NHR4; or in which Z is a group -C(R7) = NR6 in which R6 is a group OR8, where R8 is C1-4 alkyl, C2-4 alkenyl, C2-4 alkynyl, a group OCOR9 where R9 is hydrogen or R8, or a group NHR10 or NR11R12 where R10, R11 and R12 are independently C1 -2 alkyl and R7 is hydrogen or C1 -4 alkyl, subject to the proviso that when R6 is a group OCOR9 or NHR10, R7 is C1-4 alkyl.
式 (I) 的化合物或其药学上可接受的盐:
其中 Z 是杂环基团
其中 Q 代表完成 5 元芳香环的 3 元二价残基,包含 1 个或 2 个选自氧、氮和硫的杂原子,或 3 个氮原子,任何氨基氮被 C1 -2 烷基、环丙基或丙炔基取代,任何环碳原子任选被基团 R1 取代;或一个基团
其中 A1、A2 和 A3 组成一个五元芳香环,且 A1 为氧或硫,A2 和 A3 中的一个为 CR2,另一个为氮或 CR3,或 A2 为氧或硫,A1 和 A3 中的一个为 CR2,另一个为 CR3;C2-5直链烯基、C2-5直链炔基或C1-5直链烷基,任选被OR4、N(R4)2、SR4、C02R4、CON(R4)2或一个、两个或三个卤素原子末端取代,其中每个R4独立为氢或C1-3烷基,R5为OR4、NH2或NHR4;或 Z 为基团-C(R7) = NR6,其中 R6 为基团 OR8,R8 为 C1-4 烷基、C2-4 烯基、C2-4 炔基、基团 OCOR9(其中 R9 为氢或 R8)或基团 NHR10 或 NR11R12(其中 R10、R11 和 R12 独立为 C1-2 烷基,R7 为氢或 C1-4 烷基),但当 R6 为基团 OCOR9 或 NHR10 时,R7 为 C1-4 烷基。
