the major metabolite, 4, of the cancer chemopreventive oltipraz, 1, to test whether they possess similar biological activities. In the present work the mechanisms by which these compounds react with glutathione have been investigated in order to validate the assumption that they would be chemically competent in the presence of the biological thiols to give the oltipraz metabolite. A kinetic and product
化合物7-甲基-6,8-双(甲基二硫烷基)吡咯并[1,2-a]吡嗪(5;“双二硫键”)和甲硫基磺酸S-(((6-(甲磺酰基磺烷基)-7-甲基)吡咯[已经合成了1,2-a]吡嗪-8-基)酯(6;“双甲磺酸硫酯”),用作癌症化学预防oltipraz 1的主要代谢物4的替代前体,以测试它们是否具有类似的生物活性。在目前的工作中,已经研究了这些化合物与谷胱甘肽反应的机理,以证实这样的假设,即在存在生物硫醇的情况下,它们在化学上具有能力产生奥替普拉斯代谢物。动力学和产物研究主要在水性介质中进行,
