A 1,3-dihydro-2H-indol-2-one derivative expressed by Formula 1 (wherein R1 is a halogen atom, a C1 to C4 alkyl group, etc., and R2 is a hydrogen atom, a halogen atom, etc., or R2 is in the 6-position of the indol-2-one and R1 and R2 join together to form a C3 to C6 alkylene group, R3 is a halogen atom, a hydroxyl group, etc., and R4 is a hydrogen atom, a halogen atom, a C1 to C4 alkyl group, etc., or R4 is in the 3-position of the phenyl and R3 and R4 join together to form a methylenedioxy group, R5 is a hydrogen atom or a fluorine atom, R6 is an ethylamino group, a dimethylamino group, etc., R7 is a C1 to C4 alkoxy group, and R8 is a C1 to C4 alkoxy group), or a pharmaceutically acceptable salt of this derivative. This is a novel compound that has antagonistic activity against an aruginine-vasopressin V1b receptor.
公式1表示的是1,3-二氢吲哚-2-酮衍生物(其中R1是卤素原子、C1至C4烷基等,R2是氢原子、卤素原子等,或者R2位于吲哚-2-酮的6位,R1和R2结合形成C3至C6烷基,R3是卤素原子、羟基等,R4是氢原子、卤素原子、C1至C4烷基等,或者R4位于苯环的3位,R3和R4结合形成甲氧基二氧杂环丙基,R5是氢原子或氟原子,R6是乙基氨基基、二甲基氨基基等,R7是C1至C4烷氧基,R8是C1至C4烷氧基),或该衍生物的药学上可接受的盐。这是一种新型化合物,具有对抗arginine-vasopressin V1b受体的拮抗活性。
