Design, synthesis and biological profile of mixed opioid agonist/N-VGCC blocker peptides

Abstract

In this paper we reported the synthesis and the in vitro and the in vivo biological evaluation of linear pseudo-peptides incorporating the N-VGCC blocker tripeptide Phe-NMe-Leu-Tyr(OBz)-NtBu and the biphalin pharmacophore Tyr-D-Ala-Gly-Phe. The novel sequences have been designed by using amino acids of different length to join the two pharmacophores and explore the structure–activity relationships of the novel compounds.
