Analogs of substance P and eledoisin which are confor- mationally constrained by the presence of a lactam in the peptide chain demonstrate greater selectivity and increased protease stability and are useful as analgesic, anti-inflammatory, anti hypersensitive, central nervous system agents, and stimulants of lachrymal secretion. The compounds are prepared by standard peptide synthetic procedures.
