In order to search for anti-hepatitis drugs, we synthesized a series of eight- and nine-membered cyclic disulfides (1) and six- and seven-membered cyclic sulfides (2) and evaluated them for ability to reduce mortality in the model of acute hepatic failure induced by Propionibacterium acnes-lipopolysaccharide in mice. Compounds 1 were synthesized by oxidative cyclization of the corresponding dithiol
为了寻找抗肝炎药物,我们合成了一系列的八元和九元环状二硫化物(1)和六元和七元环状二硫化物(2),并在以下模型中评估了它们降低死亡率的能力:痤疮丙酸杆菌脂多糖诱导的小鼠急性肝功能衰竭。通过用溴代丙二酸二乙酯或碘对相应的二硫醇衍生物(3)进行氧化环化来合成化合物1。通过用三(二乙基氨基)膦脱硫,然后脱保护,由1的甲酯制备化合物2。通常发现化合物1比化合物2具有更高的活性。发现化合物1b(SA3443)具有有效的保护活性。讨论了合成和构效关系。
