New orally active enkephalinase inhibitors: their synthesis, biological activity, and analgesic properties
摘要:
A series of (4S)-4-[(2S)-benzyl-3-mercaptopropionylamino]-4-(N-phenylcarbamoyl)-butyric acids has been identified as potent systemically active enkephalinase inhibitors. Structure-activity relationships (SAR) are discussed. Further chemical modification of the inhibitors was carried out in order to identify the inhibitors which are orally active in an animal model. Compounds of particular interest are the prodrug-like analogues, including 5b (ONO-9902). Their analgesic effects after oral administration were evaluated. (C) 1998 Elsevier Science Ltd.

A hydantoin derivative represented by formula (I):
wherein the all symbols are defined in the disclosure. The hydantoin derivative has an inhibitory activity on metalloprotease and hence is useful as analgesic and cardiovascular drug.
