amount of various metabolites of thalidomide and related molecules generated during a combination of chiral inversion, hydrolysis, and hydroxylation were observed using liquid chromatography–tandem mass spectrometry and chiroptical spectroscopy. We found that monosubstituted thalidomide derivatives exhibited different time‐dependent metabolic patterns compared with thalidomide. We also revealed that monohydrolyzed
对映异构体沙利度胺经历各种生物转化,包括手性转化,水解和酶促氧化,这会导致多种代谢产物,从而增加了对沙利度胺本质的理解的复杂性。为了解释这种复杂性,我们在体外分析了沙利度胺和相关分子的多维代谢反应网络。使用液相色谱-串联质谱法和手性光谱法观察到了手性倒置,水解和羟基化的结合过程中沙利度胺和相关分子的各种代谢产物的量的特征模式。我们发现与沙利度胺相比,单取代的沙利度胺衍生物表现出不同的时间依赖性代谢模式。我们还发现,沙利度胺的单水解和单羟基化代谢物很可能主要由沙利度胺的C-5氧化和随后的羟基化代谢物开环产生。由于在代谢过程中大多数这些代谢物均保持手性,因此它们与未代谢的沙利度胺具有相同的手性。
