  Modification of the enkephalin "message" with an artificial polycationic C-terminus

  摘要：

  The C-terminal ''address'' sequences of prodynorphin-drived opioid peptides contain an unusually high proportion of basic residues, which are known to be crucial for conferring high activity and selectivity for kappa-opioid receptors. In an effort to investigate the possibility that the polycationic ''tails'' may be involved in a coulombic interaction with a complementary polyanionic receptor domain, we attached a series of achiral peptide-like cationic fragments to the C-terminus of the opioid peptide ''message'', Tyr-Gly-Gly-Phe. Binding of the various compounds to opioid receptor types in guinea pig brain membranes was weak, and the pharmacologic activities in the guinea pig ileum were marginal. These results indicate either that the chosen ligand design does not satisfy the structural requirements of the hypothesized coulombic interaction or that the latter is a minor criterion governing receptor recognition.
