Bile acid signaling and metabolism in the gastrointestinal tract have wide-ranging influences on systemic disease. G protein-coupled bile acid receptor 1 (GPBAR1, TGR5) is one of the major effectors in bile acid sensing, with demonstrated influence on metabolic, inflammatory, and proliferative processes. The pharmacologic utility of TGR5 agonists has been limited by systemic target-related effects
胃肠道中的胆汁酸信号和新陈代谢对全身性疾病具有广泛的影响。G蛋白偶联的胆汁酸受体1(GPBAR1,TGR5)是胆汁酸感测的主要效应器之一,已证明对代谢,炎症和增殖过程有影响。TGR5激动剂的药理作用受到全身靶标相关作用的限制,例如过多的胆囊填充和阻塞胆囊排空。但是,受肠道限制的TGR5激动剂有可能避免这些副作用,因此被开发成安全性可接受的药物。我们描述了一系列肠道受限的TGR5激动剂的发现和优化,这些激动剂在小鼠中引发了有效的反应,而胆囊相关的影响也最小。该系列包括12(TGR5 EC 50:人,143 nM;小鼠,1.2 nM),一种具有最小系统可用性的化合物,可能对2型糖尿病,非酒精性脂肪性肝炎或炎性肠病患者具有治疗价值。
