摘要:
The present invention provides a novel benzodiazepine compound that blocks the I Kur current or the Kv1.5 channel or the IKACH current (the GIRK1/4 channel) potently and more selectively than other K + channels. The benzodiazepine compound of the invention is represented by General Formula (1) wherein R 1 , R 2 , R 3 , and R 4 are each independently hydrogen or lower alkyl; R 2 and R 3 may be linked to form lower alkylene; A 1 is lower alkylene optionally substituted with one or more hydroxy; and R 5 is group represented by wherein R 6 and R 7 are each independently hydrogen or organic group; X A and X B are each independently bond, lower alkylene, etc.

The present invention provides a novel diazepine compound that blocks the I Kur current or the Kv1.5 channel potently and more selectively than other K + channels. The present invention relates to a diazepine compound represented by General Formula (1) or a salt thereof, wherein R 1 , R 2 , R 3 , and R 4 are each independently hydrogen, lower alkyl, cyclo lower alkyl or lower alkoxy lower alkyl; R 2 and R 3 may be linked to form lower alkylene; A 1 is lower alkylene optionally substituted with one or more substituents selected from the group consisting of hydroxyl and oxo; Y 1 and Y 2 are each independently -N= or -CH=; and R 5 is group represented by (2) wherein R 6 and R 7 are each independently hydrogen or organic group; R 6 and R 7 may be linked to form a ring together with the neighboring group -X A -N-X B -; X A and X B are each independently a bond, lower alkylene, etc.
摘要:
An agent for prophylaxis or treatment of cataract, which comprises as an active ingredient at least one compound selected from a group consisting of a carbostyril compound of formula (1), wherein R1 is a lower alkanoyl-substituted lower alkoxy group, and the bond between the 3- and 4-positions of the carbostyril nucleus is single bond or double bond, or a salt thereof, 5-dimethylamino-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine and 5-hydroxy-7-chloro-1-[2-methyl-4-(2-methyl-benzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine, a method for prophylaxis or treatment of cataract using the same.
