制备方法与用途

生物活性

5α-孕烷-3β,6α-二醇-20-酮是一种促有丝分裂的孕酮代谢物,在血清不足时,可以在雄性激素反应的前列腺癌细胞中生成。

体外研究

孕酮在人类成纤维细胞中可以转化为5α-孕烷-3β,6α-二醇-20-酮。在C4.2细胞系中,孕烯醇酮和孕酮几乎完全被代谢为5α-孕烷-3β,6α-二醇-20-酮,在24小时和18小时的转化率分别为近完全。早期类固醇前体主要生成5α-孕烷-3β,6α-二醇-20-酮的过程并不依赖于CYP17A1,而是依靠3β-羟化酶(3β-HSD)活性。

  • Electroreductive Olefin–Ketone Coupling

    A user-friendly approach is presented to sidestep the venerable Grignard addition to unactivated ketones to access tertiary alcohols by reversing the polarity of the disconnection. In this work a ketone instead acts as a nucleophile when adding to simple unactivated olefins to accomplish the same overall transformation. The scope of this coupling is broad as enabled using an electrochemical approach
    提出了一种用户友好的方法,通过反转断开的极性来避开古老的格氏加成法,以获取未活化酮的叔醇。在这项工作中,当加入简单的未活化烯烃以完成相同的整体转化时,酮反而充当亲核试剂。这种耦合的范围很广,因为使用电化学方法可以实现,并且反应是可扩展的、化学选择性的,并且不需要排除空气或水的预防措施。多项应用证明了多步合成反应的简化性质,机理研究指出了一种直观的机制,让人联想到其他化学还原剂,如 SmI2(不能完成相同的反应)。

  • Evaluation of the antiviral activity of natural sulfated polyhydroxysteroids and their synthetic derivatives and analogs

    Disodium 3 beta,21-dihydroxypregn-5-en-20-one disulfate (2), sodium 3 beta,21-dihydroxypregn-5-en-20-one 3-sulfate (3), sodium 3 beta,21-dihydroxypregn-5-en-20-one 21-sulfate (4), and disodium 3 beta,6 alpha-dihydroxy-5 alpha-pregnan-20-one disulfate (6) have been synthesized and completely characterized for the first time from readily available materials. Sulfation was performed using triethylamine-sulfur trioxide complex in dimethylformamide as the sulfating agent. Selective sulfation of 3 beta,21-dihydroxypregn-5-en-20-one rendered sodium 3 beta,21-dihydroxypregn-5-en-20-one 3-sulfate (3) as the major compound. The synthetic sulfated steroids as well as natural disulfated polyhydroxysteroids (7-9) isolated by us from the antarctic ophiuroid Astrotoma agassizii and the synthetic derivatives disodium 2 beta,3 alpha,21-trihydroxy-(20R)-cholesta-5,24-diene 3-acetate, 2,21-disulfate (7a) and 2 beta,3 alpha,21-trihydroxy-(20R)-cholesta-5,24-diene (7b) were comparatively evaluated for their inhibitory effect on the replication of one DNA (HSV-2) and two RNA (PV-3, JV) viruses. In general, steroids with sulfate groups at C-21 and C-2 or C-3 were the most effective in their inhibitory action against HSV-2 and also proved to be active against PV-3 and JV.
