Compounds of formula (I) are inhibitors of HSP90, and are useful inter alia in the treatment of cancers, wherein R is cyano or methoxy; R1 and R2 are independently selected from hydrogen, optionally substituted C1-C3 alkyl, and optionally substituted C3-C6 cycloalkyl; or R1 and R2 taken together with the nitrogen to which they are attached form a 3- to 7-membered ring optionally substituted by chloro, bromo, cyano, C1-C3 alkyl in which one or more hydrogens are optionally replaced by fluorine, or hydroxy(C1-C3 alkyl)- in which one or more hydrogens in the alkyl part are optionally replaced by fluorine; R3 and R4 are independently selected from hydrogen, C1-C3 alkyl in which one or more hydrogens are optionally replaced by fluorine, and cyclopropyl; or R2 and R3 taken together with the carbon to which they are attached form a 3- to 6-membered ring cycloalkyl ring; n is 1, 2 or 3; and Z is (i) -NR5R6 wherein R5 and R6 are independently selected from hydrogen, C1-C3 alkyl, and C3-C6 cycloalkyl; or R5 and R6 taken together with the nitrogen to which they are attached form a 3- to 7-membered ring optionally substituted by chloro, bromo, cyano, C1-C3 alkyl in which one or more hydrogens are optionally replaced by fluorine, or hydroxy(C1-C3 alkyl)- in which one or more hydrogens in the alkyl part are optionally replaced by fluorine; or (ii) C1-C3 alkoxy in which one or more hydrogens in the alkyl part are optionally replaced by fluorine.
式(I)的化合物是HSP90的抑制剂,在癌症治疗中很有用,其中R是氰基或甲氧基;R1和R2分别选择自氢、可选择取代的C1-C3烷基和可选择取代的C3-C6环烷基;或者R1和R2与它们连接的氮一起形成一个3-至7-成员环,该环可选择取代为氯、溴、氰基、其中一个或多个氢原子可选择被氟原子替代的C1-C3烷基,或其中一个或多个氢原子可选择被氟原子替代的羟基(C1-C3烷基)-;R3和R4独立选择自氢、其中一个或多个氢原子可选择被氟原子替代的C1-C3烷基和环丙基;或者R2和R3与它们连接的碳一起形成一个3-至6-成员环环烷基环;n为1、2或3;Z为(i) -NR5R6,其中R5和R6分别选择自氢、C1-C3烷基和C3-C6环烷基;或者R5和R6与它们连接的氮一起形成一个3-至7-成员环,该环可选择取代为氯、溴、氰基、其中一个或多个氢原子可选择被氟原子替代的C1-C3烷基,或其中一个或多个氢原子可选择被氟原子替代的羟基(C1-C3烷基)-;或(ii)其中一个或多个氢原子可选择被氟原子替代的C1-C3烷氧基。
