The synthesis of 4-methylestradiol (4-ME2) was carried out by reductive aromatization of 4-methyl-1,4-androstadiene-3-one-17 beta-ol. The relative binding affinity of 4-ME2 was found to be 10 and 25% of estradiol at 0 and 25 degrees C, respectively. 4-ME2 had considerably weaker uterotrophic activity relative to estrone and was found to have no antiuterotrophic activity.
4-甲基雌二醇(4-ME2)通过4-甲基-1,4-雄甾二烯-3-酮-17β-醇的还原芳构化反应合成。结果发现,4-ME2在0℃和25℃时的相对结合亲和力分别为雌二醇的10%和25%。相对于雌酮,4-ME2的子宫营养活性明显较弱,且发现其没有抗子宫营养活性。
