The preparation and biological properties of a conformationally constrained series of cholecystokinin-B/gastrin receptor ligands are described. The 9-membered ring (Nic) derivative was found to be as active at these receptors as an unconstrained phenylalanine analogue. (C) 1997 Elsevier Science Ltd.

The conformationallyconstrained analogues of phenylalanine, tetrahydroisoquinoline-3-carboxylic acid (Tic), Sic, Hic and Nic, and the new aminoacid Xic have been incorporated into a potent and highly selective cholecystokinin-2 (CCK(2)) receptor antagonist (2) in place of the phenylalanine residue, producing compounds 15a-e. High selectivities for CCK(2) over CCK(1) were observed for compounds 15a-e
