5-(tryptophylamino)-1,3-dioxoperhydropyrido[1,2-c]pyrimidine-based cholecystokinin receptor antagonists: reversal of CCK1 receptor subtype selectivity toward CCK2 receptors.

Abstract

With the aim of reversing selectivity or antagonist/agonist functionality in the 5-(tryptophylamino)-1,3-dioxoperhydropyrido[1,2-c]pyrimidine-derived potent and highly selective CCK(1) antagonists, a series of 4-benzyl and 4-methyl derivatives have been synthesized. Whereas the introduction of the benzyl group led, in all cases, to complete loss of the… (More)
