  • A-Ring-Modified 2-Hydroxyethylidene Previtamin D<sub>3</sub>Analogues: Synthesis and Biological Evaluation

    To investigate the biological profile of the previtamin form of vitamin D, we synthesized new analogues of 19-nor-1α,25-dihydroxyprevitamin D3 bearing a 2-hydroxyethylidene moiety at the A-ring. The target compounds were prepared by convergent synthesis using a Sonogashira coupling between an A-ring enyne synthon and a CD-ring/side-chain vinyl triflate. We have demonstrated the versatility of shikimic
    为了研究维生素 D 前维生素形式的生物学特征,我们合成了在 A 环上带有 2-羟基亚乙基部分的 19-nor-1α,25-二羟基前维生素 D3 的新类似物。使用 A 环烯炔合成子和 CD 环/侧链乙烯基三氟甲磺酸酯之间的 Sonogashira 偶联,通过会聚合成制备目标化合物。我们已经证明了莽草酸作为合成 A 环前体的起始材料的多功能性。评估了对维生素 D 受体 (VDR) 和人类维生素 D 结合蛋白 (hDBP) 的结合亲和力,以及 MCF-7 细胞的抗增殖活性。

    Efficient syntheses of A-ring synthons 24 and 32 are described from hydroxy ester 16, which is easily available on a preparative scale from (-)-quinic acid. Key features of the syntheses were (a) the ability to selectively perform desilylations in the presence of p-nitrobenzoate esters and (b) the excellent yield and complete stereospecificity with which the configuration of alcohols 16, 18, and 26
    由羟基酯16描述了A-环合成子24和32的有效合成,其可以容易地以制备规模由(-)-奎尼酸得到。合成的主要特征是(a)在对硝基苯甲酸酯存在下选择性地进行脱甲硅烷基化的能力,以及(b)在Mitsunobu下可以颠倒醇16、18和26的构型的优异收率和完全立体特异性。条件。因此,从共同的前体16制备A环合成子24和32都以35-38%的产率(八个步骤)。A环合成子24和32与合适的CD环/侧链片段7的偶联提供了访问类固醇激素1alpha,25-二羟基维生素D(3)的新型6-s-顺式类似物:1alpha,25-dihydroxy-3-epi-19-nor-previtamin D(3)(37)和1beta,25-dihydroxy-3-epi-19-nor-previtamin D(3)(38),由于没有C-19甲基而无法重新排列为相应的维生素D形式。化合物37和38可用作研究激素1α,25-二
  • Synthesis of two 6-s-cis locked stereoisomeric analogues of the steroid hormone 1α,25-dihydroxyvitamin D3: 1α,25-dihydroxy-19-nor-previtamin D3 and 1β,25-dihydroxy-19-nor-previtamin D3

    An efficient synthesis of A-ring precursors 8 and 9 from inexpensive commercially available (−)-quinic acid has been developed. A-Ring synthon 8 has been obtained through a short sequence (eight steps) in high overall yield (30%). One key step in the synthesis of A-ring precursor 9 is the selective deprotection of a silyl ether in an α,β-unsaturated ester 12. However, of note is the excellent yield
    已经开发了由廉价的可商购获得的(-)-奎尼酸有效合成A-环前体8和9的方法。通过短序列(八步)以高总产率(30%)获得了A-环合成子8。合成A环前体9的一个关键步骤是在α,β-不饱和酯12中对甲硅烷基醚进行选择性脱保护。但是,值得注意的是,Mitsunobu方法在衍生物15上的收率很高,这与构型的全部转化有关,生成了酯16。A环合成子8和9与适当的CD环/侧链片段的偶联7,提供了访问6-小号-顺式锁定类固醇激素1α的类似物,25-(OH)2 -D 3:1α,25-(OH)2 -19-也不-pre-d 3(3)的和新颖的1β,25-(OH)2 -19-或-pre-D 3(4)。
  • Chemoenzymatic synthesis and biological evaluation of C-3 carbamate analogues of 1α,25-dihydroxyvitamin D3

    The synthesis of new analogues of 1alpha,25-dihydroxyvitamin D3 containing a carbamate function at the A-ring fragment has been described using the cross-coupling approach. The carbamate group was selectively introduced at the C-3 position by regioselective enzymatic alkoxycarbonylation of A-ring enyne 3 and subsequent treatment with ammonia, amines, amino alcohols, and amino acids. Biological studies
    已经使用交叉偶联方法描述了在A-环片段上具有氨基甲酸酯功能的1α,25-二羟基维生素D 3的新类似物的合成。氨基甲酸酯基团通过A环烯炔3的区域选择性酶促烷氧基羰基化反应选择性地引入C-3位置,然后用,胺,基醇和氨基酸处理。进行了生物学研究以评估所有5种氨基甲酸酯类似物的效力,并证明与1α,25-二羟基维生素D3相比,对维生素D受体的结合亲和力非常低。此外,在抑制细胞增殖或刺激细胞分化方面,所有氨基甲酸酯类似物的活性均低于1α,25-二羟基维生素D3。在所有五个类似物中,3-O-基甲酰基-1alpha 25-(OH)2-D3类似物10a在体外是最有效的一种。然而,所有研究的氨基甲酸酯类似物在体内均显示出比母体化合物更低的减少作用。
  • Synthesis and biological activity of previtamin D3 analogues with A-ring modifications
    作者:Laura Sánchez-Abella、Susana Fernández、Annemieke Verstuyf、Lieve Verlinden、Vicente Gotor、Miguel Ferrero

    日期:2008.12.15
    Synthesis of two novel 6-s-cis analogues of 1 alpha,25-dihydroxyvitamin D-3 are described using shikimic acid and its 4-epi isomer as versatile chiral starting materials. These derivatives contain a 2b-(3'-hydroxypropoxy) moiety or a 2 beta,3 beta-epoxy group into 1 alpha,25-(OH)2-19-nor-pre-D-3. The synthesized analogues were found to be not suitable for binding to the vitamin D receptor and showed weak binding affinity toward the vitamin D-binding protein. The new derivatives failed to inhibit cell proliferation. (C) 2008 Elsevier Ltd. All rights reserved.
