Actions biochimiques/physiologiques

LY2112688 is a beta-melanocyte-stimulating hormone (β-MSH)-derived peptide that acts as a high-affinity, potent and selective melanocortin receptor 4 (MC-4, MC-4R, MC4-R, MC4R) agonist (human/rat MC-4 Ki = 0.55/0.39 nM; human MC-1/3/5 Ki = 16.78/56.79/>500 nM). LY2112688 selectively induces MC-4-mediated cAMP release (MC-4/3 EC50 = 0.25 nM/1.61 nM, MC-4/3 Emax = 94.5%/84.1% of NDP-α-MSH Emax using HEK293 expressing respective human receptors) and exhibits in vivo efficacy in reducing daily food intake and promoting weight loss among diet-induced obese rats (75 & 299 nmol/kg/day s.c.).

Paul Kievit et al.
Diabetes, 62(2), 490-497 (2012-10-11)
The melanocortin-4 receptor (MC4R) is well recognized as an important mediator of body weight homeostasis. Activation of MC4R causes dramatic weight loss in rodent models, and mutations in human are associated with obesity. This makes MC4R a logical target for
John P Mayer et al.
Journal of medicinal chemistry, 48(9), 3095-3098 (2005-04-29)
A series of novel, disulfide-constrained human beta-melanocyte stimulating hormone (beta-MSH)-derived peptides were optimized for in vitro melanocortin-4 receptor (MC-4R) binding affinity, agonist efficacy, and selectivity. The most promising of these, analogue 18, was further studied in vivo using chronic rat
Brent M Molden et al.
Molecular endocrinology (Baltimore, Md.), 29(11), 1619-1633 (2015-09-30)
The melanocortin-4 receptor (MC4R) is a G protein-coupled receptor expressed in the brain, where it controls energy balance through pathways including α-melanocyte-stimulating hormone (α-MSH)-dependent signaling. We have reported that the MC4R can exist in an active conformation that signals constitutively
Cathrine Laustrup Møller et al.
Molecular and cellular endocrinology, 341(1-2), 9-17 (2011-05-28)
The melanocortin receptors (MCRs) belong to the G-protein coupled receptors (family A). So far, 5 different subtypes have been described (MC1R-MC5R) and of these MC2R and MC5R have been proposed to act directly in adipocytes and regulate lipolysis in rodents.
Cathrine Laustrup Møller et al.
BMC research notes, 8, 559-559 (2015-10-16)
The central melanocortin system is broadly involved in the regulation of mammalian nutrient utilization. However, the function of melanocortin receptors (MCRs) expressed directly in peripheral metabolic tissues is still unclear. The objective of this study was to investigate the lipolytic
