The invention concerns an isochromane derivative having the general formula I
in which R1 is one to four substituents independently selected from hydrogen, hydroxy, alkyl (1-4 C), alkoxy (1-4 C), halogen, or CF3, or as two adjacent substituents together a methylenedioxy group; R2 is one to four substituents independently selected from hydrogen, hydroxy, alkyl (1-4 C), alkoxy (1-4 C), halogen, or CF3, or as two adjacent substituents together a methylenedioxy group; R3 is one to four substituents independently selected from hydrogen, hydroxy, alkyl (1-4 C), alkoxy (1-4 C), halogen, or CF3, or as two adjacent substituents together a methylenedioxy group; R4 is selected from hydrogen or alkyl (1-4 C); A is a bond or an alkylene or alkylidene group with 1-6 carbon atoms; B is an alkylene or alkylidene group with 1-6 carbon atoms when Y is a bond, or B is an alkylene group with 2-6 carbon atoms when Y is a group selected from 0, S, or NRs; X is CH or N; and R5 is selected from hydrogen or alkyl (1-4 C); or a pharmaceutically acceptable salt thereof.
本发明涉及一种具有通式 I 的异铬烷衍生物。
其中 R1 是独立选自氢、羟基、烷基 (1-4C)、烷氧基 (1-4C)、卤素或 CF3 的一至四个取代基,或两个相邻取代基共同组成的亚甲基二氧基;R2 是独立选自氢、羟基、烷基 (1-4C)、烷氧基 (1-4C)、卤素或 CF3 的一至四个取代基,或两个相邻取代基共同组成一个亚甲基二氧基; R3 是独立选自氢、羟基、烷基 (1-4C)、烷氧基 (1-4C)、卤素或 CF3 的一至四个取代基,或两个相邻取代基共同组成一个亚甲基二氧基;R4 选自氢或烷基(1-4 C);A 是键或具有 1-6 个碳原子的亚烷基或烯基;当 Y 是键时,B 是具有 1-6 个碳原子的亚烷基或烯基,或当 Y 是选自 0、S 或 NRs 的基团时,B 是具有 2-6 个碳原子的亚烷基;X 是 CH 或 N;以及 R5 选自氢或烷基(1-4 C);或其药学上可接受的盐。
