The excretion of four new metabolites of 2, 5, 2', 5'-tetrachlorobiphenyl (TCB) in mice feces was revealed by gas chromatographic examination. Based on mass spectrometric data and syntheses, the structures of these metabolites were identified as 3-and 4-methyl-sulfonyl-2, 5, 2', 5'-TCB (I and II, respectively), and 3-and 4-methylthio-2, 5, 2', 5'-TCB (III and IV, respectively).
通过气相色谱检查,发现小鼠粪便中排泄出四种新的2, 5, 2', 5'-四氯联苯(TCB)代谢产物。根据质谱数据和合成结果,这些代谢产物的结构被确定为3-和4-甲基磺酰基-2, 5, 2', 5'-TCB(分别为I和II)以及3-和4-甲基硫代-2, 5, 2', 5'-TCB(分别为III和IV)。
