  Design, Synthesis, and Antidiabetic Activity of 4-Phenoxynicotinamide and 4-Phenoxypyrimidine-5-carboxamide Derivatives as Potent and Orally Efficacious TGR5 Agonists

  摘要：

  4-Phenoxynicotinamide and 4-phenoxypyrimidine-5-carboxamide derivatives as potent and orally efficacious TGR5 agonists are reported. Several 4-phenoxynicotinamide derivatives were found to activate human and mouse TGR5 (hTGR5 and mTGR5) with EC50 values in the low nanomolar range. Compound 23g, with an EC50 value of 0.72 nM on hTGR5 and an EC50 value of 6.2 nM on mTGR5, was selected for further in vivo efficacy studies. This compound exhibited a significant dose-dependent glucagon-like peptide-1 (GLP-1) secretion effect. A single oral dose of 23g (50 mg/kg) significantly reduced blood glucose levels in db/db mice and caused a 49% reduction in the area under the blood glucose curve (AUC)(0-120) (min) following an oral glucose tolerance test (OGTT) in imprinting control region (ICR) mice. However, 23g stimulated gallbladder filling, which might result in side effects to the gallbladder.

  By thorough analysis of diverse structures of published TGR5 agonists, a hypothetical ligand‐based pharmacophore model was built, and a new class of potent TGR5 agonists, based on the novel 3,4,5‐trisubstituted 4,5‐dihydro‐1,2,4‐oxadiazole core, was discovered by rational design. Three distinct synthetic methods for constructing 4,5‐dihydro‐1,2,4‐oxadiazoles and extensive structure–activity relationship

  鉴于其在能量和葡萄糖稳态中的介导作用，G蛋白偶联胆汁酸受体1（TGR5）被认为是治疗2型糖尿病和其他代谢性疾病的潜在靶标。通过对已发表的TGR5激动剂的各种结构进行全面分析，建立了一个假设的基于配体的药效团模型，并基于新型3,4,5-三取代的4,5-二氢-1，2来开发了一类新型的强效TGR5激动剂。 ，4-恶二唑核是通过合理设计发现的。本文报道了三种不同的合成方法来构建4,5-二氢-1,2,4-恶二唑和广泛的结构-活性关系研究。化合物（R）-54 n，其结构是通过单晶X-射线衍射和量子化学固态TDDFT-ECD计算确定，显示出最好的效力，用EC 50为1.4的n值中号朝向hTGR5。它在体外的有利特性值得进一步研究。
