    Neurosteroid Analogues. 18. Structure–Activity Studies of ent-Steroid Potentiators of γ-Aminobutyric Acid Type A Receptors and Comparison of Their Activities with Those of Alphaxalone and Allopregnanolone
    摘要:
    A model of the alignment of neurosteroids and ent-neurosteroids at the same binding site on gamma-aminobutyric acid type A (GABA(A)) receptors was evaluated for its ability to identify the structural features in ent-neurosteroids that enhance their activity as positive allosteric modulators of this receptor. Structural features that were identified included: (1) a ketone group at position C-16, (2) an axial 4 alpha-OMe group, and (3) a C-18 methyl group. Two ent-steroids were identified that were more potent than the anesthetic steroid alphaxalone in their threshold for and duration of loss of the righting reflex in mice. In tadpoles, loss of righting reflex for these two ent-steroids 0 occurs with EC50 values similar to those found for allopregnanolone. The results indicate that ent-steroids have considerable potential to be developed as anesthetic agents and as drugs to treat brain disorders that are ameliorated by positive allosteric modulators of GABA(A) receptor function.

    4α-Aminosteroids were synthesized by the substitution of a 2α-bromo ketone using K2CO3 as an activator; 4β-aminosteroids were synthesized in excellent yields by a highly regioselective and trans-stereospecific ring opening of a steroidal 3,4α-epoxide using ZnCl2–H2O as a catalyst.
    采用K2CO3作为活化剂,通过2α-溴酮的取代反应合成了4α-氨基甾体;在ZnCl2-H2O催化剂的作用下,通过甾体3,4α-环氧化物的区域选择性和反式立体特异性环开裂反应,以优异的产率合成了4β-氨基甾体。

    A series of 5alpha-androst-3-enes and 3alpha,4alpha-epoxy-5alpha-androstanes were synthesized and tested for their abilities to inhibit aromatase in human placental microsomes. In these series the original C-17 carbonyl group was replaced by hydroxyl, acetyl and hydroxyimine groups. Inhibition kinetic analysis on the most potent steroid of these series revealed that it inhibits the enzyme in a competitive
    合成了一系列的5α-雄烯-3-烯和3α,4α-环氧-5α-雄烷酮,并测试了它们在人胎盘微粒体中抑制芳香化酶的能力。在这些系列中,原始的C-17羰基被羟基,乙酰基和羟基亚胺基取代。对这些系列中最有效的类固醇的抑制动力学分析表明,它以竞争性方式抑制酶(IC(50)= 6.5 microM)。获得的数据指出了研究类固醇的D环中C-17羰基的重要性,这是达到最大芳香化酶抑制活性所需的结构特征。此外,似乎至少一个羰基(C-3或C-17)对于有效抑制芳香化酶是必不可少的。

    In this work, new potent steroidal aromatase inhibitors both in microsomes and in breast cancer cells have been found. The synthesis of the 3,4-(ethylenedioxy)androsta-3,5-dien-17-one (12), a new steroid containing a heterocycle dioxene fused in the A-ring, led to the discovery of a new reaction for which a mechanism is proposed. New structure-activity relationships were established. Some 5β-steroids
    在这项工作中,已经发现了微粒体和乳腺癌细胞中新的有效的甾体芳香化酶抑制剂。3,4-(亚乙二氧基)androsta-3,5-dien-17-one(12)的合成是一种新的甾族化合物,其中含有杂环二恶烯稠合在A环中,导致发现了新的反应,提出了一种机制。建立了新的结构-活性关系。一些5β-类固醇(例如化合物4β,5β-环氧雄烷-17-一(9))显示出芳香化酶抑制活性,因为它们采用与芳香化酶天然底物雄烯二酮类似的A环构型。此外,还公开了增加平面度的新化学特征,特别是3α,4α-环丙烷环,如3α,4α-亚甲基-5α-雄烷-17-一(5)(IC50 =0.11μM)和Δ(9 -11)在C环中的双键,如androsta-4,9(11)-diene-3,17-二酮(13)(IC50 =0.25μM)。此外,诱导拟合对接(IFD)模拟和新陈代谢部位(SoM)预测有助于解释该酶中新的有效甾体芳香酶抑制剂的识别

    3-deoxy steroidal olefin 3a and its epoxide derivative 4a proved to be strong competitive aromatase inhibitors (K(i) = 50 and 38 nM and IC50 = 225 and 145 nM, respectively). According to our findings, the C-3 carbonyl group is not essential for anti-aromatase activity, but 5alpha-stereochemistry and some planarity in the steroidal framework is required. Furthermore, modification of the steroidal cyclopentanone
    抑制芳香酶是预防和治疗乳腺癌的有效方法。设计并合成了新的A,D环修饰的福尔马斯坦和睾丸内酯类固醇类似物,并在体外研究了它们的生化活性,以寻找新的芳香酶抑制剂并深入了解其结构活性关系(SAR)。所有测试的化合物都没有福尔马坦活性。然而,事实证明3-脱氧甾体烯烃3a及其环氧化物衍生物4a是强竞争性芳香酶抑制剂(K(i)分别为50和38 nM,IC50 = 225和145 nM)。根据我们的发现,C-3羰基对于抗芳香化酶活性不是必不可少的,但是5α-立体化学和甾体骨架中的某些平面性是必需的。此外,通过构建δ-内酯六元环对甾体环戊酮D环的修饰降低了抑制效力。根据获得的结果,可以得出结论,芳香化酶活性位点的结合袋需要在类固醇A,B环和D环结构的平面中对于结合至关重要。
