docking simulation indicated that compounds that carried two acidic groups with a proper special distance and attached to a rigid aromatic scaffold would most likely show a potent agonistic activity on hGPR35. Following this principle, we screened a list of known compounds and some were found to be potent GPR35 agonists, and compound 24 even had an EC50 of 8 nM. Particularly, a dietary supplement pyrroloquinoline
设计并合成了一系列香豆素样二酸衍生物,作为人G蛋白偶联受体35(hGPR35)的新型激动剂。活性化合物的特征在于在稠合的三环芳族支架的两侧均具有一个酸性基团。它们中的大多数充当对hGPR35选择性的完全激动剂,并且在低纳摩尔浓度下表现出出色的效能。支架中环上的取代可以有效地调节化合物的效力。结构-活性关系研究和对接模拟表明,带有两个适当距离的酸性基团并连接到刚性芳香族骨架上的化合物极有可能在hGPR35上表现出强大的激动活性。遵循这一原理,我们筛选了一系列已知化合物,发现其中一些是有效的GPR35激动剂,24甚至具有8 nM的EC 50。特别是,膳食补充剂吡咯并喹啉醌(PQQ)被确定为有效的激动剂(EC 50 = 71.4 nM)。在某种程度上,该原理提供了设计和识别GPR35激动剂的一般策略。
