Two series of conformationally constrained analogues of Pro-Leu-Gly-NH2 (PLG) have been synthesized. In one series of analogues, the Leu-Gly-NH2 dipeptide segment of PLG was replaced with the gamma-lactam residues 3(S)- and 3(R)-amino-2-oxopyrrolidineacetamide and the delta-lactam residue 3(S)-amino-2-oxopiperidineacetamide. The corresponding gamma-lactam
