these compounds was carried out via a multi-step sequence consisting of copper-catalyzed azide–alkyne cycloaddition (CuAAC) as a key step in aqueous media. The required azide was prepared via the reaction of aryl amine (obtained from nimesulide) with α-chloroacetyl chloride followed by displacing the α-chloro group by an azide. Some of the synthesized compounds showed encouraging PDE4B inhibitory properties
设计了一类来自尼美舒利的新型1,2,3-三唑衍生物作为PDE4B的潜在抑制剂。这些化合物的合成是通过多步操作完成的,该步骤由铜催化的叠氮化物-炔烃环加成反应(CuAAC)组成,是水性介质中的关键步骤。通过芳基胺(从尼美舒利获得)与α-氯乙酰氯的反应,然后用叠氮化物置换α-氯,来制备所需的叠氮化物。一些合成的化合物在体外显示出令人鼓舞的PDE4B抑制特性,即在30μM时抑制率> 50%,这是这些化合物在PDE4B酶活性位点的对接研究所支持的(代表性化合物的对接得分约为-28.6)。这些PDE4抑制剂中的两种在体外用IC对HCT-15人结肠癌细胞显示出有希望的细胞毒性50 〜21-22微克/毫升。
