Ghrelin, a gut-derived orexigenic hormone, is an endogenous ligand of the growth hormone secretagogue receptor (GHS-R). Centrally administered ghrelin has been shown to cause hunger and increase food intake in rodents. Inhibition of ghrelin actions with ghrelin antibody, peptidyl GHS-R antagonists, and antisense oligonucleosides resulted in weight loss and food intake decrease in rodents. Here we report
Ghrelin是一种肠源性致食激素,是生长激素促分泌素受体(GHS-R)的内源性配体。研究表明,集中施用的生长素释放肽可引起饥饿并增加啮齿动物的食物摄入量。用ghrelin抗体,肽基GHS-R拮抗剂和反义寡核苷酸抑制ghrelin的作用导致啮齿类动物体重减轻和食物摄入减少。在这里,我们报告了GHS-R拮抗剂的作用,其中一些是有效的,选择性的和口服生物利用的。构效关系研究导致了8a的发现,在一些急性大鼠研究中,它可有效减少食物摄入和减轻体重。
