代谢
Cabazitaxel在肝脏中广泛代谢(>95%),主要由CYP3A4/5同工酶(80%至90%)代谢,其次是由CYP2C8代谢,产生20种不同的代谢物。其中两种代谢物是cabaxitaxel的活性去甲基衍生物,分别被称为RPR112698和RPR123142。Docetaxel是cabazitaxel的另一种代谢物。Cabazitaxel是人类血浆中的主要循环物质。
Cabazitaxel is extensively metabolized in the liver (>95%), mainly by the CYP3A4/5 isoenzyme (80% to 90%), and to a lesser extent by CYP2C8 which results in 20 different metabolites. Two of these metabolites are active demethylated derivatives of cabaxitaxel and referred to as RPR112698 and RPR123142 respectively. Docetaxel is another metabolite of cabazitaxel. Cabazitaxel is the main circulating moiety in human plasma.
