Abstract

A new demethylated metabolite, extracted from erythromycin-induced rabbit liver microsomes incubation media, isolated by HPLC and identified by FAB/MS and NMR, is described. Moreover, NMR spectra suggest the existence of tautomeric forms of this O-demethylated metabolite of FK506.

摘要

描述了一种新的去甲基化代谢产物,它从红霉素诱导的兔肝微粒体孵育介质中提取,通过高效液相色谱法(HPLC)分离,并通过快原子轰击质谱法(FAB/MS)和核磁共振法(NMR)鉴定。此外,核磁共振谱表明存在这种FK506的O-去甲基化代谢产物的互变异构形式。
