  • Comparative study of in vivo stigmasterol biosynthesis in Nicotiana tabacum and Hordeum vulgare

    Hordeum vulgare ) seedlings rapidly incorporated and metabolized exogenously supplied [4- 14 C]sitosterol but neither plant was able to convert it into stigmasterol. However, a sterol metabolite was isolated from both species and the acetate derivative was slightly more polar, on AgNO 3 —silica gel TLC, than stigmasteryl acetate. A similar metabolite was also obtained with [4- 14 C]cholesterol, indicating
    摘要 六日龄烟草 (Nicotiana tabacum) 和大麦 (Hordeum vulgare) 幼苗迅速吸收并代谢外源提供的 [4- 14 C] 谷甾醇,但两种植物均无法将其转化为豆甾醇。然而,在 AgNO 3 -硅胶 TLC 上,从这两个物种中分离出甾醇代谢物,并且乙酸衍生物的极性比豆甾醇乙酸酯略强。[4- 14 C]胆固醇也获得了类似的代谢物,表明植物对外源性甾醇的一般代谢反应。两种物种都将[2- 14 C]甲羟戊酸掺入谷甾醇和豆甾醇中。我们建议,在维管植物中,无论是单子叶植物还是双子叶植物,豆甾醇的生物合成途径不是通过谷甾醇而是通过来自甲羟戊酸的常见前体。

    A Mutated strain of Nocardia corallina IFO 3338 accumulated following substances as cholesterol degradation products, 3aα-H-4α-[3'-propionic acid]-5α-hydroxy-7aβ-methylhexa-hydro-l-indanone-δ-lactone (VIII), 3aα-H-4α-[3'-trans acrylic acid]-5α-hydroxy-7aβ-methyl-hexahydro-l-indanone (IX) and 3aα-H-4α-acetyl-5α-hydroxy-7aβ-methylhexahydro-1-inda-none (X). Substance X is a new compound in the microbial degradation of sterols. These substances were also produced from steroid other than cholesterol, such as β-chole-stanol, β-sitosterol, soy bean sterol (mixture), cholest-4-en-3-one, lithocholic acid, cholic acid and progesterone. A degradation pathway has been proposed for steroids by Nocardia corallina: cholesterol or other sterols_??_3aα-H-4α-[3'-propionic acid]-7aβ-methylhexahydro-l, 5-indanedione or compound VIII_??_3aα-H-4α-[3'-trans acrylic acid]-7aβ-methylhexahydro-l, 5-indanedione or compound IX_??_3aα-H-4α-acetyl-7aβ-methylhexahydro-1, 5-indanedione or compound X_??_C02+H2O.

    4-oxa-5-sitosten-3-one, the enol-lactone of the ke~oacid of sitosterol (IV), with phenyl acetate-2-1~C. A twofold excess of the relatively expensive phenyl acetate-2-1~C was utilized for this. The description of this synthesis in the work [4] is insufficiently detailed for satisfactory reproducibility. The synthesis of ~-sitosterol-4-~C presented in the work [5], starting from the same enol-lactone, appeared more
    ~-谷甾醇 (I) 是一种具有重要生物学意义的天然甾醇。环中用 I~C 标记的谷甾醇及其同系物胆固醇以前是通过两种方法获得的 [4, 5]。在工作 [4] 中,由于 4-oxa-5-sitosten-3-one(酮酸的烯醇内酯)的缩合,经过一系列转化后得到 B-sitosterol-3-14C。谷甾醇 (IV),与 2-1~C 苯乙酸酯。为此使用了两倍过量的相对昂贵的乙酸苯酯-2-1-C。工作 [4] 中对这种合成的描述不够详细,无法获得令人满意的重现性。工作 [5] 中提出的 ~-sitosterol-4-~C 的合成,从相同的烯醇-内酯开始,似乎更具吸引力。甲基-~C碘化镁,很容易从可用的甲基-'~C碘化物中获得,用于引入标签。我们选择了最后一种方法来分离 6-sitostero!-~C。对原始方法 [5] 进行了一系列更改,涉及初始化合物和标记产品本身的分离。合成所必需的化合物(I)
