Melanocortin receptor agonists

hormone

group of peptide hormones in Homo sapiens

chemical compound

Afamelanotide, sold under the brand name Scenesse, is a medication used to prevent phototoxicity and to reduce pain from light exposure for people with erythropoietic protoporphyria. It is a melanocortin 1 receptor (MC1 receptor) agonist and a synthetic peptide and analogue of α-melanocyte stimulating hormone. It is administered as subcutaneous implant.

The melanocortins are a family of neuropeptide hormones which are the ligands of the melanocortin receptors. The melanocortin system consists of melanocortin receptors, ligands, and accessory proteins. The genes of the melanocortin system are found in chordates. Melanocortins were originally named so because their earliest known function was in melanogenesis. It is now known that the melanocortin system regulates diverse functions throughout the body, including inflammatory response, fibrosis, melanogenesis, steroidogenesis, energy homeostasis, sexual function, and exocrine gland function.

peptide hormone in Homo sapiens

chemical compound

Setmelanotide, sold under the brand name Imcivree, is a medication used for the treatment of genetic obesity caused by a rare single-gene mutation.

Alsactide (INN; brand name Synchrodyn 1-17 or simply Synchrodyn; former development code Hoechst 433; also known as alisactide) is a synthetic peptide and analogue of adrenocorticotropic hormone (ACTH) which is used in Italy as a diagnostic agent in kidney function for adrenal insufficiency. Like ACTH, alsactide is thought to act as a non-selective agonist of the melanocortin receptors, including the ACTH receptor (MC2R). However, it appears to show a different profile of receptor selectivity relative to ACTH, as it apparently demonstrated no evidence of inhibition of endogenous ACTH in Addiso
