Discovery of 1-amino-4-phenylcyclohexane-1-carboxylic acid and its influence on agonist selectivity between human melanocortin-4 and -1 receptors in linear pentapeptides
摘要:
Linear pentapeptides (Penta-cis-Apc-DPhe-Arg-Trp-Gly-NH2) containing 1-amino-4-phenylcyclohexane-1-carboxylic acid (cis-Apc) and substituted Apc are potent hMC4R agonists and they are inactive or weakly active in hMC1R, hMC3R, and hMC5R agonist assays. This study, together with our earlier report on 5-BrAtc, demonstrated the importance of replacing His6 with phenyl-containing rigid templates in achieving good hMC4R agonist potency and selectivity against hMC1R in linear pentapeptides.

The present invention relates to an ionic complex comprising a cationic polypeptide and an anionic excipient selected from: a PEG-carboxylic acid; a fatty acid having 10 or more carbon atoms; an anionic phospholipid; and a combination thereof. The invention also relates to a pharmaceutical composition comprising the ionic complex of the invention and a pharmaceutically acceptable carrier. The cationic polypeptide of the ionic complex has pharmacological activity and the complex can provide a more desirable pharmacokinetic profile for the cationic polypeptide of the complex as compared to the cationic polypeptide alone following administration. As such, the invention also relates to the use of the ionic complex and pharmaceutical composition comprising same to treat a subject suffering from a disease or disorder that is responsive to the cationic polypeptide of the ionic complex.
