CCK-4 restricted analogues containing a 3-oxoindolizidine skeleton
摘要:
A series of CCK-4 restricted analogues, incorporating a 3-oxoindolizidine bicyclic lactam as conformational constraint, is described. The 8-(Boc-tryptophyl)amino-2-benzyl derivatives behave as weak CCK-A or CCK-B receptor antagonists. The main factors for selectivity are the configuration at C-2 position of the 3-oxoindolizidine ring and at the Trp residue. Copyright (C) 1996 Elsevier Science Ltd
