The noncationizable tripeptide Ac-D-Trp-Phe-GlyNH(2) was recently proposed as a novel minimal recognition motif for mu-opioid receptor. The introduction of different substituents (methyl, halogens, nitro, etc.) at the indole of D-Trp significantly influenced receptor affinities and resulted in serum stability and in a measurable effect on central antinociception in mice after ip administration.

Abstract
The noncationizable tripeptide Ac-D-Trp-Phe-GlyNH(2) was recently proposed as a novel minimal recognition motif for mu-opioid receptor. The introduction of different substituents (methyl, halogens, nitro, etc.) at the indole of D-Trp significantly influenced receptor affinities and resulted in serum stability and in a measurable effect on central antinociception in mice after ip administration.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
