  Nonpolar and Short Side Chain Groups at C-11β of Estradiol Result in Antiestrogens

  摘要：

  We have previously found that esters of 11beta-estradiol carboxylates are transformed from an estrogen into an antiestrogen when the 11beta-side chain is increased in length from four to five non-hydrogen atoms (n greater than or equal to 5). To understand the structural requirements for this transformation and obtain metabolically stable analogues that are not susceptible to esterase cleavage, we have synthesized other compounds having an 11beta-side chain composed of other functional groups: ketones, amides, ethers, and thiono esters. With the exception of amides, which bind poorly to the estrogen receptor (ER), all of these compounds exhibit antiestrogenic action when the side chain length is n greater than or equal to 5. Ethers (n greater than or equal to 5), studied in more detail, inhibit the action of estradiol with either ERalpha or ERbeta. In rat uteri they are estrogen antagonists/weak agonists and decrease the concentration of cholesterol in blood (an hepatic estrogenic action). Thus, these short chain and nonpolar 11beta-analogues of estradiol have tissue specific antiestrogenic/estrogenic actions, characteristics of selective estrogen receptor modulators.

  beta-vinyl moiety was established by X-ray crystallography. The final product and several analogues, 11 beta-ethyl-, -vinyl-, and (hydroxyethyl)estradiols (11, 5, and 12), were evaluated for their estrogen receptor binding affinity. The results indicate that the target compound and several 11 beta-substituted analogues possess relative binding affinities greater than of estradiol and its 16 alpha-fluorinated

  作为开发用于核医学的雌激素放射性配体的计划的一部分，进行了一项研究，以研究取代基对假定放射化学物质的受体亲和力的影响。在这项研究中，设计了一种针对11β-（氟乙基）取代基引入的合成策略。通过五步程序从11β-乙烯基雌酮3-乙酸酯（4）开始以五步法制备目标化合物9，总产率为43％。通过X射线晶体学确定了11个β-乙烯基部分的立体化学。评价了最终产物和几种类似物，即11β-乙基-，-乙烯基-和（羟乙基）雌二醇（11、5和12）的雌激素受体结合亲和力。结果表明目标化合物和几种11个β-取代的类似物的相对结合亲和力大于雌二醇及其16个α-氟化衍生物。制备目标化合物9的方式适合与18F结合使用。
