The instant invention provides novel benzothiophene compounds of the formula
wherein:
R1 is -H, -OH, -O(C1-C4 alkyl), -O-CO-(C1-C6 alkyl), -O-CO-O(C1-C6 alkyl), -O-CO-Ar in which Ar is optionally substituted phenyl, -O-CO-O-Ar in which Ar is optionally substituted phenyl, or -O-SO2-(C4-C6 alkyl);
R2 is -H, -OH, -O(C1-C4 alkyl), -O-CO-(C1-C6 alkyl), -O-CO-O(C1-C6 alkyl), -O-CO-Ar in which Ar is optionally substituted phenyl, -O-CO-O-Ar in which Ar is optionally substituted phenyl, -O-SO2-(C4-C6 alkyl), -F, -Cl, or -Br;
n is an integer from 3 to 8;
R3 and R4 each are independently C1-C4 alkyl, or combine to form, with the nitrogen to which they are attached, piperidinyl, pyrrolidinyl, methylpyrrolidinyl, dimethylpyrrolidinyl, or hexamethyleneimino;
with the proviso that when n is 3, then neither R1 nor R2 can be -O-SO2-(C4-C6 alkyl); or a pharmaceutically acceptable salt or solvate thereof.
本发明提供了式中的新型
苯并噻吩化合物
其中
R1是-H、-OH、-O(C1-C4烷基)、-O-CO-(C1-C6烷基)、-O-CO-O(C1-C6烷基)、-O-CO-Ar(其中Ar是任选取代的苯基)、-O-CO-O-Ar(其中Ar是任选取代的苯基)或-O-SO2-(C4-C6烷基);
R2是-H、-OH、-O(C1-C4烷基)、-O-CO-(C1-C6烷基)、-O-CO-O(C1-C6烷基)、-O-CO-Ar(其中Ar是任选取代的苯基)、-O-CO-O-Ar(其中Ar是任选取代的苯基)、-O-SO2-(C4-C6烷基)、-F、-Cl或-Br;
n 是 3 至 8 的整数;
R3和R4各自独立地为C1-C4烷基,或与所连接的氮结合形成
哌啶基、
吡咯烷基、甲基
吡咯烷基、二甲基
吡咯烷基或六亚甲基亚
氨基;
但当 n 为 3 时,R1 和 R2 均不能为-O-SO2-(C4-C6 烷基);或其药学上可接受的盐或溶液。
