Biological activity of analogues of YM022. Novel (3-amino substituted phenyl)urea derivatives of 1,4-benzodiazepin-2-one as gastrin/cholecystokinin-B receptor antagonists

Article abstract of DOI:10.1248/cpb.44.1412

A series of (3-substituted phenyl)urea analogues of the potent gastrin/cholecystokinin (CCK)-B receptor antagonist YM022 has been prepared. Structure activity relationship studies of this series suggested that a number of analogues retained good in vitro potency for gastrin/CCK-B receptor. In particular, the (3-amino substituted phenyl)urea derivatives (10-12) were more potent inhibitors of pentagastrin-induced gastric acid secretion in rats than YM022 on intraduodenal (i.d.) administration.
