代谢
外源性雌激素的代谢机制与内源性雌激素相同。雌二醇可以可逆地转化为雌酮,两者都可以转化为雌三醇,这是主要的尿代谢物。雌激素还通过肝脏中的硫酸盐和葡萄糖醛酸苷结合、胆汁中将结合物分泌到肠道、肠道中的水解以及随后再吸收,经历肠肝循环。在绝经后女性中,循环中的雌激素有很大一部分以硫酸盐结合物的形式存在,尤其是雌酮硫酸盐,它作为形成更具活性雌激素的循环储备。
Exogenous estrogens are metabolized using the same mechanism as endogenous estrogens. Estradiol is converted reversibly to estrone, and both can be converted to estriol, which is the major urinary metabolite. Estrogens also undergo enterohepatic recirculation via sulfate and glucuronide conjugation in the liver, biliary secretion of conjugates into the intestine, and hydrolysis in the gut followed by reabsorption. In postmenopausal women, a significant proportion of the circulating estrogens exist as sulfate conjugates, especially estrone sulfate, which serves as a circulating reservoir for the formation of more active estrogens.

吸收、分配和排泄
  • 吸收
Femring的药物释放速度在第一个小时是迅速的,然后在接下来的3个月用药间隔内逐渐下降到一个相对恒定的速率。醋酸雌二醇迅速被水解为雌二醇,通过阴道粘膜吸收,雌二醇达到最高浓度的时间(tmax)大约为1小时(范围0.25到1.5小时)。在达到最高浓度(Cmax=1129pg/mL)后,血清中的雌二醇迅速下降,以至于在用药后24到48小时,血清中的雌二醇浓度在3个月用药间隔结束前保持相对恒定。
Drug delivery from Femring is rapid for the first hour and then declines to a relatively constant rate for the remainder of the 3-month dosing interval. Estradiol acetate is rapidly hydrolyzed to estradiol which is absorbed through the vaginal mucosa as evidenced by the mean time to maximum concentration (tmax) for estradiol of about 1 hour (range 0.25 to 1.5 hrs). Following the maximum concentration (Cmax=1129pg/mL), serum estradiol decreases rapidly such that by 24 to 48 hours postdose, serum estradiol concentrations are relatively constant through the end of the 3-month dosing interval.

    摘要:
    Tetrapropylammonium perruthenate N-methylmorpholine N-oxide oxidation of steroidal alcohols is described. The reagent combination is mild and gave good yields of the corresponding ketones. Although the oxidation can generate ketones from 3-, 11-, 15-, 17-, and 20-hydroxy steroids, the oxidation of homoallylic alcohols proceeds in low yields. Finally, we observed that the oxidation reagents will convert 17alpha-hydroxy-20-keto steroids to 17-keto systems in excellent yield.

  • MANGANESE (III) CATALYZED C--H AMINATIONS

    Reactions that directly install nitrogen into C—H bonds of complex molecules are significant because of their potential to change the chemical and biological properties of a given compound. Selective intramolecular C—H amination reactions that achieve high levels of reactivity, while maintaining excellent site-selectivity and functional-group tolerance is a challenging problem. Herein is reported a manganese perchlorophthalocyanine catalyst [Mn III (ClPc)] for intermolecular benzylic C—H amination of bioactive molecules and natural products that proceeds with unprecedented levels of reactivity and site-selectivity. In the presence of Brønsted or Lewis acid, the [Mn III (ClPc)]-catalyzed C—H amination demonstrates unique tolerance for tertiary amine, pyridine and benzimidazole functionalities. Mechanistic studies indicate that C—H amination proceeds through an electrophilic metallonitrene intermediate via a stepwise pathway where C—H cleavage is the rate-determining step of the reaction. Collectively these mechanistic features contrast previous base-metal catalyzed C—H aminations.
    直接将氮原子安装到复杂分子中的C-H键的反应具有重要意义,因为它们有可能改变给定化合物的化学和生物性质。实现高反应性,同时保持优秀的位点选择性和官能团耐受性的选择性分子内C-H胺化反应是一个具有挑战性的问题。本文报道了一种锰过氯酞菁催化剂[MnIII(ClPc)],用于分子间苄基C-H胺化反应,该反应在生物活性分子和天然产物中以前所未有的反应性和位点选择性进行。在Brønsted酸或Lewis酸的存在下,[MnIII(ClPc)]催化的C-H胺化展示了对叔胺、吡啶和苯并咪唑官能团的独特耐受性。机理研究表明,C-H胺化通过亲电金属亚硝烯中间体经过分步途径进行,其中C-H裂解是反应的速率决定步骤。总的来说,这些机理特征与之前基于贱金属催化的C-H胺化反应形成了对比。
