  Synthesis and in Vitro Activity of 3β-Substituted-3α-hydroxypregnan-20-ones:  Allosteric Modulators of the GABA_A Receptor

  摘要：

  Two naturally occurring metabolites of progesterone, 3 alpha-hydroxy-5 alpha- and 5 beta-pregnan-20-one (1 and 2), are potent allosteric modulators of the GABA(A) receptor. Their therapeutic potential as anxiolytics, anticonvulsants, and sedative/hypnotics is limited by rapid metabolism. To avoid these shortcomings, a series of 3 beta-substituted derivatives of 1 and 2 was prepared. Small lipophilic groups generally maintain potency in both the 5 alpha- and 5 beta-series as determined by inhibition of [S-35]TBPS binding. In the 5 alpha-series, 3 beta-ethyl, -propyl, -trifluoromethyl and -(benzyloxy)methyl, as well as substituents of the form 3 beta-XCH(2), where X is Cl, Br, or I or contains unsaturation, show limited efficacy in inhibiting [S-35]TBPS binding. In the 5 beta-series, the unsubstituted parent 2 is a two-component inhibitor, whereas all of the 3 beta-substituted derivatives of 2 inhibit TBPS via a single class of binding sites. In addition, all of the 3-substituted 5 beta-sterols tested are full inhibitors of [S-35]TBPS binding. Electrophysiological measurements using alpha 1 beta 2 gamma 2L receptors expressed in oocytes show that 3 beta-methyl- and 3 beta-(azidomethyl)-3 alpha-hydroxy-5 alpha-pregnan-20-one (6 and 22, respectively) are potent full efficacy modulators and that 3 alpha-hydroxy-3 beta-(trifluoromethyl)-5 alpha-pregnan-20-one (24) is a low-efficacy modulator, confirming the results obtained from [S-35]TBPS binding. These results indicate that modification of the 3 beta-position in 1 and 2 maintains activity at the neuroactive steroid site on the GABA(A) receptor. In animal studies, compound 6 (CCD 1042) is an orally active anticonvulsant, while the naturally occurring progesterone metabolites I and 2 are inactive when administered orally, suggesting that 3 beta-substitution slows metabolism of the S-hydroxyl, resulting in orally bioavailable steroid modulators of the GABA(A) receptor.

  雄甾酮衍生物抑制17β-羟基类固醇脱氢酶类型3的A和D环结构修饰：化学合成与结构-活性关系。

  摘要：

  通过使用3β17β-羟基类固醇脱氢酶（17β-HSD3）抑制剂来减少肿瘤内雄激素的生物合成是治疗前列腺癌的策略。雄甾酮（ADT）衍生物1（RM-532-105）对17β-HSD3具有强抑制活性，但有待改进。在这里，我们描述了两个系列类似物的化学合成和表征，以解决A和D环修饰对17β-HSD3抑制活性，雄激素作用和代谢稳定性的影响。通过在C16 / C17上添加不同的基团（D环多样化）或用正雄烷或雌激素骨架取代ADT骨架（A环多样化）来生成结构活性关系。与铅化合物1相比，D环衍生物的抑制剂作用更弱 而甾体骨架（A环）的变化导致鉴定出有前途的新型雌激素衍生物。最后用有效的17β-HSD3抑制剂23、27、31和33（IC50分别为0.10、0.02、0.13和0.17μM）达到终点，该抑制剂不刺激LAPC-4细胞增殖，并且在小鼠中的血浆浓度高于铅。化合物1。
