Four endogenous products of oxidative bilirubin degradation were isolated and fully characterized. The constitutional isomers belong to the propentdyopents (PDPs). Their structures and further oxidative transformations to biologically active bilirubin oxidation end products (Z-BOXes) are reported. Using liquid chromatography–mass spectrometry protocols, PDPs were detected in human bile and gallstones

胆红素降解的四个内源性产物被分离并得到充分表征。组成异构体属于propentdyopents(PDP)。据报道它们的结构和进一步的氧化转化为
生物活性
胆红素氧化终产物(Z- BOXes)。使用
液相色谱-质谱联用规程,在人的胆汁和胆结石中检测到了PDP。鉴于最近对将BOX作为脑血管痉挛和肝功能障碍的效应子的兴趣,共同出现的PDP代表了要考虑的另一种潜在活性化合物。
