Synthesis and platelet aggregation inhibiting activity of acid side-chain modified hydantoin prostaglandin analogues.

abstract：:Biphalin [(Tyr-D-Ala-Gly-Phe-NH-)2 ] is an octapeptide with mixed μ/δ opioid activity. Its structure is based on two identical enkephalin-like portions linked "tail-to-tail" by a hydrazine bridge. This study presents the synthesis and in vitro and in vivo bioassays of two biphalin analogs that do not present the toxic...
