    作者:Anna Bertinotti、Giacomo Carrea、Gianluca Ottolina、Sergio Riva

    日期:1994.1
    polyhydroxylated steroids has been systematically investigated. The enzyme showed a mark preference forthe alcoholic moieties on the A ring and on the steroidal side chain, making it possible the selective acylation at the positions 3 or 21 of polyhydroxy steroids. Acylation with the synthetically useful ester choloroacetate and levulinate was also accomplished, whereas esterification with benzoate and

    for NADP(H) over NAD(H) at a physiological pH of 7.4. In the NADPH-linked reduction, 3HBD showed broad substrate specificity for a variety of quinones, ketones and aldehydes, including 3-, 17- and 20-ketosteroids and prostaglandin D(2), which were converted to 3alpha-, 17beta- and 20alpha-hydroxysteroids and 9alpha,11beta-prostaglandin F(2), respectively. Especially, alpha-diketones (such as isatin
    3-羟基己异巴比妥脱氢酶(3HBD)催化将NAD(P)(+)链接的3-羟基己异巴比妥氧化为3-羟基己异巴比妥。该酶被认为是异生物醇和某些羟基类固醇的脱氢酶,但其生理功能仍然未知。我们已经纯化了兔3HBD,分离了其cDNA,并检查了其对辅酶和底物的特异性,反应方向性和组织分布。3HBD是醛酮还原酶(AKR)超家族的成员(AKR1C29),并且在7.4的生理pH值下,NADP(H)优于NAD(H)。在与NADPH相关的还原反应中,3HBD对多种醌,酮和醛(包括3-,17-和20-酮类固醇和前列腺素D(2))显示出广泛的底物特异性,它们被转化为3alpha-,17beta-和20alpha -羟基类固醇和9alpha,11beta-前列腺素F(2),分别。特别是,α-二酮(如isatin和diacetyl)和脂质过氧化衍生的醛(如4-oxo-和4-hydroxy-2-nonenals)是显示低K(m)值(0
  • Characterization of hamster NAD<sup>+</sup>-dependent 3(17)β-hydroxysteroid dehydrogenase belonging to the aldo-keto reductase 1C subfamily
    作者:Satoshi Endo、Misato Noda、Akira Ikari、Kenjiro Tatematsu、Ossama El-Kabbani、Akira Hara、Yukio Kitade、Toshiyuki Matsunaga

    The cDNAs for morphine 6-dehydrogenase (AKR1C34) and its homologous aldo-keto reductase (AKR1C35) were cloned from golden hamster liver, and their enzymatic properties and tissue distribution were compared. AKR1C34 and AKR1C35 similarly oxidized various xenobiotic alicyclic alcohols using NAD+, but differed in their substrate specificity for hydroxysteroids and inhibitor sensitivity. While AKR1C34 showed 3α/17β/20α-hydroxysteroid dehydrogenase activities, AKR1C35 efficiently oxidized various 3β- and 17β-hydroxysteroids, including biologically active 3β-hydroxy-5α/β-dihydro-C19/C21-steroids, dehydroepiandrosterone and 17β-estradiol. AKR1C35 also differed from AKR1C34 in its high sensitivity to flavonoids, which inhibited competitively with respect to 17β-estradiol (Ki 0.11–0.69 μM). The mRNA for AKR1C35 was expressed liver-specific in male hamsters and ubiquitously in female hamsters, whereas the expression of the mRNA for AKR1C34 displayed opposite sexual dimorphism. Because AKR1C35 is the first 3(17)β-hydroxysteroid dehydrogenase in the AKR superfamily, we also investigated the molecular determinants for the 3β-hydroxysteroid dehydrogenase activity by replacement of Val54 and Cys310 in AKR1C35 with the corresponding residues in AKR1C34, Ala and Phe, respectively. The mutation of Val54Ala, but not Cys310Phe, significantly impaired this activity, suggesting that Val54 plays a critical role in recognition of the steroidal substrate.
    从金黄地鼠肝脏中克隆了羟基脱氢酶(AKR1C34)及其同源醛酮还原酶(AKR1C35)的 cDNA,并比较了它们的酶学性质和组织分布。AKR1C34 和 AKR1C35 均能利用 NAD+ 氧化各种外源性的脂环醇,但在羟基类固醇的底物特异性和抑制剂敏感性方面有所不同。AKR1C34 显示出 3α/17β/20α-羟基类固醇脱氢酶活性,而 AKR1C35 能有效氧化多种 3β-和 17β-羟基类固醇,包括具有生物活性的 3β-羟基-5α/β-二氢C19/C21-类固醇、脱氢表雄酮和 17β-雌二醇。AKR1C35 在黄酮类化合物的高敏感性方面也与 AKR1C34 不同,黄酮类化合物以竞争方式抑制 17β-雌二醇(Ki 0.11–0.69 μM)。AKR1C35 的 mRNA 在雄性地鼠中肝脏特异性表达,而在雌性地鼠中普遍表达,AKR1C34 的 mRNA 表达则显示出相反的性二态性。由于 AKR1C35 是 AKR 超家族中第一个 3(17)β-羟基类固醇脱氢酶,我们还通过将 AKR1C35 中的 Val54 和 Cys310 替换为 AKR1C34 中的相应残基 Ala 和 Phe,研究了 3β-羟基类固醇脱氢酶活性的分子决定因素。Val54Ala 突变显著损害了这一活性,而 Cys310Phe 突变则没有,这表明 Val54 在识别甾体底物中起着关键作用。
  • Phosphine Effects in the Copper(I) Hydride-Catalyzed Hydrogenation of Ketones and Regioselective 1,2-Reduction of α,β-Unsaturated Ketones and Aldehydes. Hydrogenation of Decalin and Steroidal Ketones and Enones
    作者:Jian-Xin Chen、John F. Daeuble、Jeffrey M. Stryker
    DOI:10.1016/s0040-4020(00)00133-2
    日期:2000.4
    The stereoselectivity and regioselectivity of the catalytic hydrogenation of ketones and α,β-unsaturated ketones and aldehydes using soluble copper(I) hydride catalysts have been investigated as a function of the ancillary phosphine ligand. While a relatively narrow range of aryldialkylphosphine ligands produce active hydrogenation catalysts, some ligands provide higher selectivity for 1,2-reduction
    已经研究了使用可溶性氢化铜(I)催化剂催化酮和α,β-不饱和酮和醛催化氢化的立体选择性和区域选择性,它是辅助膦配体的函数。尽管相对窄范围的芳基二烷基膦配体产生活性氢化催化剂,但某些配体比使用先前报道的二甲基苯基膦稳定的催化剂观察到的对1,2-还原无环不饱和羰基底物的选择性更高。这类氢化氢化催化剂的合成用途可以通过十氢化萘和甾族酮和烯酮的氢化来说明,后者能提供高选择性的烯丙醇。
  • 17-(O-(2-Carboxyethyl)oxime) Derivatives of Androstanes of 3-Hydroxy-5α-, -5β-, -5-ene and 3-Oxo-4-ene Series
    作者:Vladimír Pouzar、Ivan Černý
    DOI:10.1135/cccc19950137
    日期:——

    Androstane 17-(O-(2-carboxyethyl)oxime) derivatives were prepared either by the reaction of 17-keto derivatives with corresponding substituted hydroxylamine or by the addition of 17-oximino derivatives to the alkyl acrylate and subsequent hydrolysis. Oxidation of the hydroxy group in position 3 in derivatives of this type was performed either by the Oppenauer reaction, transforming 5-ene derivatives into 3-oxo-4-enes, or with Jones reagent in the case of saturated 5α- or 5β-derivatives. Configuration 17E in the whole series of oximes was confirmed by the 1H and 13C NMR spectroscopy.

    雄烷17-(O-(2-羧乙基)肟)衍生物可以通过17-酮衍生物与相应取代羟胺的反应或通过将17-肟衍生物加入烷基丙烯酸酯并随后水解来制备。在这类衍生物中,位置3的羟基氧化可以通过Oppenauer反应将5-烯衍生物转化为3-酮-4-烯,或者在饱和的5α-或5β-衍生物中使用Jones试剂来进行。整个肟系列中17E构型通过1H和13C核磁共振谱确认。
