title: Analgesic activity of certain tripeptide-beta-phenethylamide analogs.
abstract: Studies of the analgesic effect of tripeptide-beta-phenethylamides are described, and their structure-activity relationship is discussed. SD-25, which has a methyl group at R2, and a hydroxymethyl group at R3 of beta-phenethylamide, was the most potent one of the 8 analogs tested.
