制备方法与用途

生物活性

3-氧胆固醇酸是一种氧胆汁酸的代谢产物,也是产气荚膜梭菌在肠道中由胆汁产生的主要降解产物。它是一种类固醇酸,主要存在于哺乳动物的胆汁中。

体内研究

雄性Goto-Kakizaki (GK)大鼠经过回肠转位(IT)手术后,在代谢组学分析中发现,与假手术-IT大鼠相比,IT大鼠的3-氧胆固醇酸水平显著增加。

  • Oxidation of alcohols by electrochemically regenerated nickel oxide hydroxide. Selective oxidation of hydroxysteroids
    作者:Johannes Kaulen、Hans-J. Schäfer
    DOI:10.1016/0040-4020(82)80110-5
    日期:1982.1
    Primary alcohols, α,ω-diols and secondary alcohols are easily transformed into carboxylic acids, dicarboxylic acids or ketones, respectively, by heterogeneous oxidation with nickel oxide hydroxide electrochemically regenerated at a nickel hydroxyde electrode. The results are discussed in comparison to those of the nickel peroxide and chromic acid oxidation. The oxidation rate decreases with increasing
    伯醇,α,ω-二醇和仲醇很容易分别通过在氢氧化镍镍电极上电化学再生的氧化镍氢氧化物进行多相氧化而分别转化为羧酸,二羧酸或酮。与过氧化镍和铬酸氧化的结果进行了讨论。氧化速率随着醇的空间位阻的增加而降低,从而允许羟基甾族化合物中3位的选择性氧化。

    12-diketo-5 beta-cholan-24-oic acid (7,12-diketolithocolic acid) as the main product. A number of different chemical reductions were carried out on DHCA; among them hydrogenation with Raney Nickel in water under high-intensity ultrasound proved highly regio- and stereoselective, yielding 7,12-diketolithocolic acid exclusively. (1)H and (13)C resonances were assigned in details thanks to a series of 1D and 2D
    脱氢胆酸 (DHCA) 是一种非天然胆汁酸,由胆酸氧化制成。据报道,它通过两种担子菌(Trametes hirsuta 和 Collybia velutipes)进行生物转化。这些菌丝体对底物和攻击选择性表现出不同的亲和力:T. hirsuta 特别是区域选择性和立体选择性还原 3-keto 基团以产生 3 alpha-hydroxy-7,12-diketo-5 beta-cholan-24-oic acid (7,12-diketolithocolic acid) 为主要产品。对 DHCA 进行了许多不同的化学还原;其中,在高强度超声下与雷尼镍在水中的氢化证明具有高度的区域和立体选择性,仅产生 7,12-二酮基乙醇酸。由于一系列 1D 和 2D NMR 运行,包括 DEPT、NOESY、HH COSY、gHSQC 和 gHMBC,详细指定了 (1)H 和 (13)C 共振。
  • Bile acids. LXXIX. synthesis and reduction of 1,4-dien-3-ones of various bile acids
    作者:Mohammed N. Iqbal、William H. Elliott
    DOI:10.1016/0039-128x(89)90022-6
    日期:1989.3
    bile acids (IIa-d), their methyl esters (IIe-h), and their formylated derivatives (IIi-k) were synthesized and their reduction investigated by both catalytic and chemical methods as an alternative route to the synthesis of allo bile acids. Lithium-ammonia reduction proved to be the better method for the reduction of these 1,4-dien-3-ones producing the 3-keto- and 3 beta-hydroxy-allo bile acids (Vb-d)
    合成了各种胆汁酸 (IIa-d) 的 1,4-Dien-3-ones、它们的甲酯 (IIe-h) 和它们的甲酰化衍生物 (IIi-k),并通过催化和化学方法研究了它们的还原情况,如合成别胆汁酸的另一种途径。锂-氨还原被证明是还原这些 1,4-二烯-3-酮的更好方法,产生 3-酮-和 3-β-羟基-别胆酸 (Vb-d) 和 (VIb-d)产率为 66-72%。
  • Synthesis and antitumor activity of alkylated bile acids and oxazolines
    作者:Srđan Bjedov、Dimitar Jakimov、Mihalj Poša、Olivera R. Klisurić、Marija Sakač
    DOI:10.1016/j.tet.2017.10.058
    日期:2017.12
    Bile acid derivatives with a free carboxylic group or an oxazoline ring in the side chain and with different lengths of alkyl chains on steroid skeleton were synthetized and their antitumor activity against six human cancer cell lines was investigated. Methyl, ethyl, butyl or octyl chains were introduced stereoselectively by Grignard reaction at C-7 of acid and oxazoline, and at C-12 of oxazoline.
    合成了在侧链上具有游离羧基或恶唑啉环且在甾族骨架上具有不同烷基链长度的胆汁酸衍生物,并研究了它们对六种人类癌细胞系的抗肿瘤活性。通过格氏反应在酸和恶唑啉的C-7和恶唑啉的C-12处立体选择性地引入甲基,乙基,丁基或辛基链。酸化合物C-12处的羰基仅与甲基格氏试剂产生加成产物,而产物与其他用过的试剂形成复杂混合物。由于烯醇化,C-3羰基不参与格氏反应。严格原因是这种化学行为的主要原因。在C-7位置带有丁基链的化合物显示出非常好的抗肿瘤活性,IC 50  <5μM。
