Oxidation of two tyrosine kinase inhibitors (TKIs) sunitinib and pazopanib, using a chemical catalytic system able to mimic the cytochrome P450 type oxidation, allowed us to prepare putative reactive/toxic metabolites of these anticancer drugs. Among these metabolites, aromatic aldehyde derivatives were unambiguously characterized. Such biomimetic oxidation of TKI-type drugs was essential to facilitate
使用能够模拟细胞色素P450型氧化的化学催化系统氧化两种酪氨酸激酶抑制剂(TKI)舒尼替尼和帕唑帕尼,使我们能够制备这些抗癌药的假定反应性/毒性代谢物。在这些代谢产物中,芳香醛衍生物得到了明确的表征。当与人肝微粒体(HLM)孵育时,TKI型药物的这种仿生氧化作用对于促进鉴定由这些TKI生成的少量醛至关重要,而人肝微粒体(HLM)是人肝代谢的经典模型。这些TKI衍生物醛在体外能与胺快速反应。预期在体内会发生类似的反应,并且可能是这些TKI潜在的严重肝毒性的起因。
