Chemical synthesis of six novel 17β-estradiol and estrone dimers and study of their formation catalyzed by human cytochrome P450 isoforms

Chen, Aaron Yun,Lee, Anthony J.,Jiang, Xiang-Rong,Bao, Ting Zhu

, p. 5372 - 5381 (2008/03/13)

Our earlier studies have shown that over 20 nonpolar 17β-estradiol metabolite peaks were detected following incubations of radioactive 17β-estradiol with human liver microsomes or recombinant human cytochrome P450 isoforms in the presence of NADPH as a co
