代谢
肝脏代谢。代谢的第一阶段主要是还原性的。产生了还原产物3 beta-羟基-5alpha-雄烷-4,17-二酮和3alpha-羟基-5beta-雄烷-4,17-二酮,并进一步还原。代谢过程中的一个显著步骤是在分子第三个碳上的酮还原。从福美斯坦产生的主要代谢物是4-羟基雄-4-烯-3,17-二酮-4-葡萄糖苷酸。确定的氧化产物是4-羟基雄甾-4,6-二烯-3,17-二酮和4-羟基雄甾-1,4-二烯-3,17-二酮。在第二阶段,结合反应是多样的,包括硫酸化和葡萄糖苷酸化。4-羟基睾酮,作为福美斯坦的17-羟基化类似物,是在女性尿液中发现的特定代谢物之一。这一发现是在女性口服500毫克福美斯坦后的结果。
Hepatic metabolism. Phase I of metabolism is mainly reductive in nature. The reduction products 3 beta-hydroxy-5alpha-androstane-4,17-dione and 3alpha-hydroxy-5beta-androstane-4,17-dione are produced, and further reduced. A notable step in the process of metabolism is a keto reduction on carbon number three of the molecule. The main metabolite which is produced from formestane is 4-hydroyxyandrost-4-ene-3,17-dione-4-glucuronide. The oxidation products identified were 4-hydroxyandrosta-4,6-diene-3,17-dione and 4-hydroxyandrosta-1,4-diene-3,17-dione. In phase II, conjugation was diverse and included sulfatation and glucuronidation. 4-hydroxytestosterone, the 17-hydroxylated analog to formestane, was identified as one particular metabolite found in women's urine. This finding was the result of an oral administration of 500mg of formestane in women.

吸收、分配和排泄
  • 吸收
Formestane 口服生物利用度较差,但通过已建立的肌肉内给药途径则可完全生物利用。静脉脉冲给药后的药时曲线下面积(AUC)与肌肉内给药相比没有显著变化。在一项研究中,首次肌肉内给予 Formestane 24-48 小时内,达到了 48.0 +/- 20.9 nmol/l 的 C(max) 值。
Formestane has poor oral bioavailability, but is fully bioavailable when administered via the established intramuscular route. The AUC after an intravenous pulse dose does not vary considerably from that of an intramuscular dose. Within 24-48 h of the first dose of intramuscular formestane, a C(max) of 48.0 +/- 20.9 nmol/l was achieved in one study. [2]

  • 清除
血浆清除率大约为4.2 L/(h kg),当通过静脉给药时。在女性中,服用500毫克福美斯坦后,24小时内20%以葡萄糖苷酸形式排出。[1]一种长期代谢物(3beta,4alpha-二羟基-5alpha-雄甾烷-17-酮)可以在90小时内被检测到。更灵敏的技术可能会使检测时间更长,这可能在体育药物检测中有用。[1]
Plasma clearance is approximately 4.2 L/(h kg), when delivered intravenously. In women, following a 500mg dose of formestane, 20% was excreted as glucuronide within the first 24 hours. [1] One long term metabolite (3beta,4alpha-dihydroxy-5alpha-androstan-17-one) can be detected for 90 hours. A longer detection time is possible with more sensitive technology, which may be of utility in sports drug testing. [1]

制备方法与用途

概述

福美司坦(Formestane)是由Ciba-Geigy制药公司研发的第二代芳香化酶抑制剂(Aromatase Inhibitors),于1993年上市。其化学名为4-羟基雄甾-4-烯-3,17-二酮,分子式为C₁₉H₂₆O₃,相对分子质量为302.41,是生理甾体激素雄烯二酮(Androstenedione)的衍生物。福美司坦能够与芳香化酶高度特异性结合,有效阻断内源性雄激素与酶的结合,从而阻止雄激素转化为雌激素,降低血浆内雌激素水平,达到抑制乳腺癌细胞的效果。

临床应用

本药可选择性地抑制芳香化酶,在外周组织和癌组织中阻断由雄激素向雌激素转化的过程,减少体内雌激素水平,进而抑制乳腺癌的生长。福美司坦因特异性高,不会影响肾上腺皮质激素的合成,因此不需要补充糖皮质激素,也不会引起雄激素前体的蓄积。

在III期临床试验中,使用本药的患者中有28%达到客观缓解,26%达到病情稳定。II期临床研究显示,在接受本药作为二线治疗药物的妇女中,平均缓解持续时间为13-33个月,显著优于氨鲁米特和甲地孕酮。

药代动力学

福美司坦与其他芳香化酶抑制剂无交叉耐药性,无氨鲁米特的副作用。口服后胃肠道快速吸收,血药浓度达峰时间约为1~1.5小时,但个体差异较大;肌注后药物可在注射部位缓慢释放。表现为双相消除过程,初始半衰期为2~4天,终末半衰期为5~10天。福美司坦主要在肝脏代谢,并以糖苷酸类代谢产物的形式从尿液中排泄。

注意事项

禁用于绝经前、怀孕及哺乳期妇女。肝肾功能不良者无需调整剂量。驾车或操作机器时应小心,因偶见报告有头昏、嗜睡或昏睡现象。本药不适用于儿童。

化学性质

福美司坦从含水甲醇结晶后熔点为199~202℃;从乙酸乙酯结晶后熔点为203.5~206℃。其UV最大吸收在99.5%乙醇中波长为278nm,ε值为11,030。旋光度[α]₂₀⁺值为+181°(C=7.7,氯仿)。

用途

福美司坦是一种芳香化酶抑制剂,用于治疗进行性乳腺癌;同时也具有雄性激素和同化蛋白类的特性,并用作芳酶抑制药。

生产方法
  1. 将雄甾-4-烯-3,17-二酮(Ⅰ)(1.432g,5mmo1)溶于50ml叔丁醇中,在室温下加入38mg(0.15mmo1)四氧化锇的溶液和5ml 35%双氧水。
  2. 在室温下搅拌3天后加100ml盐水稀释,用二氯甲烷(2×100m1)提取。提取液依次用100ml盐水、50ml 10%亚硫酸氢钠溶液、50ml 10%碳酸钠溶液和100ml盐水洗。
  3. 使用无水硫酸钠干燥,浓缩后剩余物(1.824g)为化合物(Ⅱ),熔点200~202℃(丙酮)。
  4. 将化合物(Ⅱ)溶于10ml甲醇中,加入氢氧化钾(393mg,7mmo1)在3ml甲醇中的溶液,在55℃下搅拌10min。加毕,加入0.3ml乙酸和100ml盐水。
  5. 用二氯甲烷(2×100m1)提取合并的液相,浓缩后剩余物经硅胶柱层析(己烷-乙酸乙酯7:3)洗脱,得福美司坦715mg,收率47%,熔点200~202℃(丙酮)。

    Aromatase inhibitors. Synthesis and biological activity of androstenedione derivatives
    摘要:
    The synthesis and biological evaluation of androstenedione derivatives as inhibitors of estrogen biosynthesis are described. The results show that 4-hydroxy analogues are among the most potent in vitro inhibitors of the series. Esterification of the 4-hydroxy steroids generally reduced activity. Further conjugation of the 3-keto 4-ene system to give 4-hydroxy-4,6-androstadiene-3,17-dione caused more rapid inactivation of aromatase in rat ovarian microsomes than 4-hydroxyandrostenedione. Some compounds exhibited differences in activity when tested for inhibition of human placental microsomes vs. rat ovarian microsomes. The 4-hydroxyandrostenedione derivatives and their nonbulky esters were generally more potent in vitro and in vivo inhibitors than other substituted steroids in the series. Several of the synthesized compounds markedly reduce (50-81%) estrogen levels in rats on proestrus and/or had antifertility action. To date, none of the compounds surpassed the in vivo inhibitory action of 4-hydroxy-4-androstene-3,17-dione or its 4-acetate derivative.
