various biologically active products. As human nonpancreatic sPLA2 is present in high levels in the blood of patients in several pathological conditions, the potent sPLA2 inhibitors have been suggested to be useful drugs. Here we describe the synthesis, structure-activity relationship, and inhibitory activities of indolizine and indene derivatives. 1-(Carbamoylmethyl)indolizine derivatives and 1-oxamoylindolizine
磷脂酶A2是一种水解某些细胞磷脂的sn-2位的酶。释放的溶血磷脂和花生四烯酸是各种生物活性产物生物合成中的前体。由于人类非胰腺sPLA2在几种病理状况下都以高水平存在于患者的血液中,因此有力的sPLA2抑制剂被认为是有用的药物。在这里,我们描述了吲哚嗪和茚衍生物的合成,构效关系以及抑制活性。1-(氨基甲酰基甲基)吲哚并嗪衍生物和1-氧肟基吗啉衍生物表现出非常强的抑制活性。前者对空气氧化不稳定,但后者在稳定性和效能上均表现出改善。一些化合物接近发色测定的化学计量极限。
