amide group of Darapladib with an imidazole or a triazole. Unfortunately, the inhibitory activities of these derivatives were lower than that of Darapladib. But interestingly, a series of quaternary ammonium salts that were isolated as by-products during this synthetic work were found with high potency. Of these by-products, compound 22c showed a similar profile to Darapladib both in vitro and in vivo
新的Lp-PLA 2抑制剂是通过用咪唑或三唑生物替代Daradladib的酰胺基来合成的。不幸的是,这些衍生物的抑制活性低于达拉帕地布。但是有趣的是,发现了在合成过程中作为副产物分离出的一系列季铵盐,具有很高的效力。在这些副产物中,化合物22c在体外和体内均显示出与达拉帕地相似的特性。
