GC–MS (SIM mode) method for the identification of potential phase I metabolites in vivo. Plasma analysis of Wistar rats orally administered with lapachol revealed two metabolites, α-lapachone and dehydro-α-lapachone. Hence, the biomimetic model with a manganese salen complex has evidenced its use as a valuable tool to predict and elucidate the in vivo phase I metabolism of lapachol and possibly also
以雅各布森(Jacobsen)催化剂(锰(III)salen)和碘代苯作为氧化剂,通过仿生模型体外研究了生物活性萘醌拉帕酚。因此确定了11种氧化衍生物,并假定了2种竞争性氧化途径。类似于Mn(III)卟啉,Jacobsen催化剂主要诱导拉帕酚的对萘醌衍生物,但也诱导两种邻位衍生物的形成。氧化产物用于开发GC-MS(SIM模式)方法,用于鉴定体内潜在的I相代谢产物。口服拉帕酚的Wistar大鼠的血浆分析发现有两种代谢物,α-拉帕酮和脱水α-拉帕酮。因此,具有锰salen复合物的仿生模型已证明其可作为预测和阐明拉帕酚以及其他生物活性天然化合物的体内I相代谢的有价值的工具。
