Selective, High Affinity Peptide Antagonists of α-Melanotropin Action at Human Melanocortin Receptor 4: Their Synthesis and Biological Evaluation in Vitro†

TL;DR: Examination of the sequences of these new peptides revealed that the D-(2')Nal(7)-Arg(8)-Trp(9) segment of peptide 1 forms the "essential core" required for high affinity and high selectivity of analogues of peptides of compound 1 at hMC-4R.
Journal ArticleDOI

Analogs of MTII, Lactam Derivatives of α-Melanotropin, Modified at the N-Terminus, and Their Selectivity at Human Melanocortin Receptors 3, 4, and 5

TL;DR: Proline-substituted analogs of MTII, a potent nonselective agonist at melanocortin receptors, were prepared by solid-phase syntheses and evaluated for their ability to bind and activate human MC-3, MC-4, and MC-5 receptors and it was demonstrated that the N-terminal fragment ofMTII has virtually no effect on the binding affinity and activation at hMC-4R, but it is essential for full potency at h MC
Journal ArticleDOI

Potent and selective peptide agonists of alpha-melanotropin action at human melanocortin receptor 4: their synthesis and biological evaluation in vitro.

TL;DR: The cyclic derivatives of alphaMSH of a general structure, cyclo(X-His-d-Phe-Arg-Trp-Y)-NH(2), where X is succinic acid or an omega-amino-carboxylic acid, and Y is an alpha,omega-di-aminos-car boxylic Acid, turned out to be potent and receptor-specific agonists at melanocortin receptors 3 and 5.
