Definitions
- the present invention relates to melanocortin receptor agonist compounds, their preparation and their therapeutic application.
- MC-Rs Melanocortin receptors
- MC-Rs belong to the G-protein coupled receptor super-family with seven transmembrane domains. Their transduction pathway involves the production of cAMP (Cone, R. D., Recent Prog Horm Res., 1996, 51, 287).
- Five subtypes of MC-Rs are currently described, MC1-R, MC2-R, MC3-R, MC4-R and MC5-R, and are expressed in different tissues such as the brain (MC3, 4, 5-R) , the exocrine glands (MC5-R), the adrenal glands (MC2-R) and the skin (MC1-R) for the main ones.
- the natural ligands of the MC-Rs are, for the agonists, ACTH, a, ⁇ and ⁇ -MSH, and for the agonists, the agouti protein and Pagouti-related protein. None of the natural ligands is highly selective for any of the subtypes, except for ⁇ -MSH, which has some selectivity for MC3-R.
- the melanocortin system is involved in many physiological processes, including pigmentation, inflammation, eating and sexual behavior (including erectile function), energy balance (body weight regulation and lipid storage), exocrine function, protection and neuronal regeneration, immunomodulation, analgesia, etc.
- MC4-R has been shown to be involved in sexual behavior (Van der Ploeg, LH, Proc Natl Acad ScL USA, 2002, 99, 11381, Martin, WJ, Eur J. Pharmacol. 2002, 454, 71). It has also been demonstrated, through mouse models specifically lacking in some MC-Rs (knockout mice), that central MC-Rs (MC3 and 4-R) were involved in eating behavior, obesity, metabolism and energy balance (Huszar, D., IECI, 1997, 88 (1), '131; Chen AS, Nat Genet, 2000, 26 (1), 97;. Butler, AA, Trends Genet 2001 17, S50-S54). Thus, MC4-R knockout mice are hyperphagic and obese. At the same time, MC3 and / or 4R antagonists favor food intake, whereas stimulation of MC4-R by an endogenous agonist, such as ⁇ -MSH, produces a satiety signal.
