H2S donor abilities of 18 dithiolethione and dithiolone analogs of ADT and ADO upon incubation with rat liver microsomes. It shows that, for all the studied compounds, maximal H2S formation was obtained after incubation with microsomes and NADPH and that this formation greatly decreased in the presence of N-benzylimidazole, a known inhibitor of cytochrome P450. This indicates that H2S formation from
据报道,ADT (5-(p-甲氧基苯基)-3H-1,2-dithiole-3-thione, anetholedithiolethion, Sulfarlem) 和 ADO (5-(p-甲氧基苯基)-3H-1,2) 的微粒体代谢-dithiole-3-one, anetholedithiolone) 导致 H2S 的形成,主要来源于由细胞色素 P450 依赖性单加氧酶催化的氧化作用,并且在这些条件下,ADO 是比 ADT 更好的 H2S 供体。本文比较了 18 种二硫硫酮和 ADT 和 ADO 的二硫醇酮类似物与大鼠肝微粒体孵育后的 H2S 供体能力。它表明,对于所有研究的化合物,在与微粒体和 NADPH 孵育后获得了最大的 H2S 形成,并且这种形成在 N-苄基咪唑(一种已知的细胞色素 P450 抑制剂)存在下大大减少。这表明所有研究的化合物形成 H2S 需要,正如之前在 ADT 和 ADO
