Synthesis, receptor binding studies, optical spectroscopic and in silico structural characterization of morphiceptin analogs with cis-4-amino-L-proline residues

Abstract

Three novel morphiceptin analogs, in which Pro in position 2 and/or 4 was replaced by cis-4-aminoproline connected with the preceding amino acid through the primary amino group, were synthesized. The opioid receptor affinities, functional assay results, enzymatic degradation studies and experimental and in silico structural analysis of such analogs are presented.
