Y. Takeda et al., SYNTHESIS OF PHENOXYACETIC ACID-DERIVATIVES AS HIGHLY POTENT ANTAGONISTS OF GASTRIN CHOLECYSTOKININ-B RECEPTORS - II/, Chemical and Pharmaceutical Bulletin, 46(6), 1998, pp. 951-961
A series of phenoxyacetanilide derivatives was synthesized and their a
ntagonist activities for human gastrin/cholecystokinin (CCK)-B and CCK
-A receptors were evaluated. Among the compounds synthesized, bamoylme
thyl)carbamoylmethyl]-ureido]phenyl]acetic acid (20i, DA-3934) exhibit
ed high affinity for gastrin/CCK-B receptors and high selectivity over
CCK-A receptors. DA-3934 and its methyl ester derivative inhibited pe
ntagastrin-induced gastric acid secretion in rats in a dose-dependent
manner.
