  • Chemoselective Oxidation of <i>p</i>-Methoxybenzyl Ethers by an Electronically Tuned Nitroxyl Radical Catalyst
    作者:Shohei Hamada、Koichi Sugimoto、Elghareeb E. Elboray、Takeo Kawabata、Takumi Furuta

    日期:2020.7.17
    The oxidation of p-methoxy benzyl (PMB) ethers was achieved using nitroxyl radical catalyst 1, which contains electron-withdrawing ester groups adjacent to the nitroxyl group. The oxidative deprotection of the PMB moieties on the hydroxy groups was observed upon treatment of 1 with 1 equiv of the co-oxidant phenyl iodonium bis(trifluoroacetate) (PIFA). The corresponding carbonyl compounds were obtained

  • Characterization of Two Isoforms of Mouse 3(17).ALPHA.-Hydroxysteroid Dehydrogenases of the Aldo-Keto Reductase Family

    Mouse kidney contains two 3(17)α-hydroxysteroid dehydrogenases (HSDs) that show essentially the same properties except for their isoelectric points. However, the structural differences and physiological roles of the two enzymes remain unknown. In this study, we have isolated cDNAs for the two 3(17)α-HSDs from a total RNA sample of mouse kidney by reverse transcription-PCR. The identity of the cDNAs was confirmed by characterization of the recombinant enzymes that showed the same molecular weights, pI values, pH optima, substrate specificity and inhibitor sensitivity as those of the enzymes from mouse kidney. We also found that the recombinant enzymes reduce precursors of neuroactive progesterone derivatives, 5α-dihydrotestoserone, deoxycorticosterone, dehydroepiandrosterone, dehydroepiandrosterone sulfate and estrone at low Km values of 0.3—2 μM. The two enzymes belonged to the aldo-keto reductase (AKR) family, and their 323-amino acid sequences differed only by five amino acids. The sequences of the two isoforms are identical to those of proteins that are predicted to be encoded in a gene for AKR1C21 in the database of the mouse genome. However, the mRNAs for the two isoforms were expressed in mouse kidney and other tissues, in which their expression levels were different. The results indicate an important role of 3(17)α-HSD in controlling the concentrations of various steroid hormones in the mouse tissues, and suggest the existence of two genes for the two isoforms of the enzyme.
    小鼠肾脏含有两种3(17)α-羟基类固醇脱氢酶(HSD),它们的基本性质相同,除了等电点不同。然而,这两种酶的结构差异和生理作用仍然未知。在本研究中,我们通过逆向转录-PCR从小鼠肾脏总RNA样本中分离得到了两种3(17)α-HSD的cDNA。通过重组酶的特性鉴定确认了cDNA的身份,这些重组酶显示出与小鼠肾脏来源酶相同的分子量、等电点、pH最适值、底物特异性和抑制剂敏感性。我们还发现,这些重组酶能以低Km值0.3—2 μM还原神经活性孕酮衍生物前体、5α-二氢睾酮、去氧皮质酮、脱氢表雄酮、脱氢表雄酮硫酸酯和雌酮。这两种酶属于醛酮还原酶(AKR)家族,它们的323个氨基酸序列仅相差五个氨基酸。这两种异构体的序列与预测在老鼠基因组数据库中的AKR1C21基因编码的蛋白质序列一致。然而,这两种异构体的mRNA在小鼠肾脏和其他组织中表达,其表达水平不同。结果表明,3(17)α-HSD在小鼠组织中控制各种类固醇激素的浓度中起着重要作用,并提示这两种酶异构体存在两种基因。

    根据Dutcher 和Wintersteiner2,在通常条件下通过Wow-Kishner 方法还原C3-类固醇酮主要产生相应的Cs-差向异构甲醇和少量预期的Cs-亚甲基产物。在α,P-不饱和酮、胆甾酮的情况下,还原遵循更复杂的过程。除了差向异构不饱和甲醇和少量正常产物A4-胆甾醇外,还分离出饱和甲醇、α-粪甾醇和P-胆甾醇。作者指出,异常还原可以通过以下假设来解释:腙或缩氨基脲部分水解为游离酮,然后被醇钠还原为仲醇。然而,这些可能性被修改后的 WolffKishner red ~ ction 消除,~ , ~ 其中水在加热期间蒸发。此外,该反应中使用过量的水合肼应将再生酮的浓度保持在较低水平。 2 事实上,迄今为止研究的所有 C3-甾体酮都通过改性的 Wolff-Kish20-二酮孕烷得到了正常的 C3-亚甲基化合物(I) 得到在 152-153' 熔化的还原产物,其中两个酮基中的一个未

  • HOF·CH3CN, made directly from F2 and water, as an ecologically friendly oxidizing reagent
    作者:Shlomo Rozen、Yifat Bareket、Moshe Kol

    The complex HOF·CH3CN, made directly from fluorine and aqueous acetonitrile, was used for oxidation of secondary alcohols and for Baeyer Villiger oxidation of ketones. By using 18O labeled reagent it was found that the ketone oxidation proceeds through the original dioxirane mechanism which Baeyer and Villiger suggested a century ago for reactions with peracids but was later discounted.
