our endeavours to synthesize immunosuppressive agents from α-santonin, we report herein the design and synthesis of a new series of α-santonin derived O-aryl/aliphatic ether, ester and amide analogs and the evaluation of their immunosuppressive activities. The in vitro studies led to several analogs with significant immunosuppressive effects by inhibiting ConA and LPS stimulated T- and B-cell proliferation
为了继续努力从α-桑顿蛋白合成免疫抑制剂,我们在此报告了一系列新的α-桑顿蛋白衍生的O-芳基/脂族醚,酯和酰胺类似物的设计和合成,以及它们的免疫抑制活性的评估。在体外通过抑制刀豆和LPS导致了几个类似物与显著免疫抑制作用研究刺激T细胞和B细胞的增殖以剂量依赖的方式。与α-桑顿蛋白1相比,更重要的化合物4d,4e,4f,4h,6a和6b对有丝分裂原诱导的T细胞和B细胞增殖具有抑制作用。。化合物4e表现出惊人的体外免疫抑制作用,分别抑制〜80%的B和〜75%的T淋巴细胞增殖。在体内对BALB调查/ c小鼠显示,无细胞毒性的化合物4E抑制体液免疫和细胞免疫。
