CA 2437492

The present invention provides a compound of the formula: wherein ring A is an optionally substituted 5 to 10-membered aromatic ring; R1 and R2 are the same or different and each is an optionally substituted hydrocarbon group or an optionally substituted heterocyclic group; X is a bond and the like; and L is a divalent hydrocarbon group, and a salt thereof, except 3-(aminomethyl)-2,6,7- trimethyl-4-phenyl-1(2H)-isoquinolinone, 3-(aminomethyl)-2-methyl-4-phenyl- 1(2H)-isoquinolinone, 3-(aminomethyl)-6-chloro-2-methyl-4-phenyl-1(2H)- isoquinolinone and 3-(aminomethyl)-2-isopropyl-4-phenyl-1(2H)-isoquinolinone. The compound shows a superior peptidase-inhibitory activity and is useful as an agent for the prophylaxis or treatment of diabetes and the like.

L'invention concerne un composé représenté par la formule (I), dans laquelle le noyau A est un noyau aromatique doté de 5 à 10 chaînons éventuellement substitué ; R?1¿ et R?2¿ sont identiques ou différents, et chacun représente un groupe hydrocarbure éventuellement substitué ou un groupe hétérocyclique éventuellement substitué ; X représente une liaison et analogue ; et L représente un groupe hydrocarbure divalent.
