The invention provides a novel α-halogen-substituted thiophene compound salt that has a potent LPA receptor antagonistic action and is useful as a medicament.
The salt is represented by the general formula (I):
(wherein R is a hydrogen atom or a methoxy group; X is a halogen atom; A is selected from the group consisting of:
M is an alkali metal or an alkaline earth metal; and n is 1 when M is an alkali metal and is 2 when M is an alkaline earth metal).
本发明提供了一种新型α-卤代
噻吩化合物盐,它具有强效的 LPA 受体拮抗作用,可用作药物。
该盐由通式(I)表示:
(其中 R 是氢原子或甲氧基;X 是卤素原子;A 选自以下组成的组:
M 是碱
金属或碱土
金属;当 M 是碱
金属时,n 为 1;当 M 是碱土
金属时,n 为 2)。
