Studies on analgesic oligopeptides. II. Structure-activity relationship among thirty analogs of a cyclic dipeptide, cyclo(-Tyr-Arg-)

Thirty diketopiperazines were synthesized as analogs of cyclo(-Tyr-Arg-). The analgesic activities of these analogs were evaluated after intracerebral administration in mice. In the cyclo(-X-Arg-) series of analogs, cyclo[-Tyr(Et)-Arg-] showed the most po
