HS-024 (trifluoroacetate salt)
(Synonyms: Ac-Cys-Nle-Arg-His-D-Nal-Arg-Trp-Gly-Cys-NH2; cyclic [AcCys3,Nle4,Arg5,D-Nal7,Cys-NH211]α-MSH-(3-11)) 目录号 : GC92098HS-024 (trifluoroacetate salt)是黑皮质素受体4的环肽拮抗剂(MC4R;Ki=0.29nM)。
Sample solution is provided at 25 µL, 10mM.
HS-024 is a cyclic peptide antagonist of melanocortin receptor 4 (MC4R; Ki = 0.29 nM).1 It is selective for MC4R over MC1R, MC3R, and MC5R (Kis = 18.6, 5.45, and 3.29 nM, respectively). HS-024 (100 nM) inhibits cAMP accumulation induced by α-melanocyte-stimulating hormone (α-MSH) in COS-1 cells expressing human MC1R, MC3R, MC4R, or MC5R. It increases food intake in rats when administered at doses of 0.3, 1, or 3 nmol/animal. Intrathecal administration of HS-024 (1.5 nmol/animal) inhibits mechanical allodynia at 30 minutes post-injection in a rat model of spinal nerve ligation-induced neuropathic pain.2 It reduces stress-induced reinstatement of nicotine seeking in the foot shock test in rats.3
