Free fatty acid receptor 4 (FFA4) has been recognized as an attractive target in metabolic diseases. To find potent and selective FFA4 agonist, 28 compounds of 3-(4-(phenoxymethyl)phenyl)propanoic acid and N-phenylbenzenesulfonamide derivatives were designed and synthesized, featuring OC and SO2-N linkage. For the OC linkage compounds, 1g showed the most potent FFA4 agonistic activity with a pEC50

脂肪酸受体4(FFA4)已被认为是代谢性疾病的诱人靶标。为了找到有效和选择性的FFA4激动剂,设计并合成了具有O C和SO2-N键的28种3-(4-(苯氧基甲基)苯基)
丙酸和N-苯基苯磺酰胺衍
生物。对于O C键化合物,1g的FFA4激动作用最强,p
EC 50为5.81±0.04,对FFA1的选择性至少为64倍。对于SO2-N键合激动剂,2m的p
EC 50为5.66±0.04,对FFA1的选择性> 46倍。在这两个系列的化合物中,1g对接模拟显示,它是FFA4最有效的激动剂和对FFA1的最佳选择性。此外,1g对其他七个
GPCR表现出受体选择性。在抗糖尿病评估中,1g剂量依赖性地降低了血糖,优于临床III期药物
TAK875。这项研究为FFA4
配体设计和药物优化提供了指导。
