  • Deoxycholic acid degradation by a pseudomonas sp: Phenolic and neutral products
    作者:R.A. Leppik
    DOI:10.1016/s0040-4020(01)98940-9
    日期:1981.1
    The microbial degradation of deoxycholic acid by Pseudomonas sp. MR108 was studied, and four products were isolated. Evidence is presented that one is the phenol 3,12β - dihydroxy - 9,10 - secoandrosta -1,3,5(10) - trien - 9,17 - dione (11) and that the other three are the neutral compounds 3aαH - 4α - [3' - propionic acid] - 5α - hydroxy - 7aβ - methyl - hexahydro -1 - indanone - δ - lactone (12)
    假单胞菌(Pseudomonas sp。)对脱氧胆酸的微生物降解。研究了MR108,并分离了四种产物。证据表明,一个是酚3,12β-二羟基-9,10-二十烷二酚-1,3,5(10)-trien-9,17-二酮(11),另外三个是中性化合物3aαH- 4α-[3'-丙酸]-5α-羟基-7aβ-甲基-六氢-1-茚满酮-δ-内酯(12),12β-羟基androsta -1,4-二烯-3,17-二酮(10),和12α-羟基雄甾烷-1,4-二烯-3,17-二酮(7)。
  • Microbial degradation of steroids to hexahydroindanone derivatives.

    DOI:10.1271/bbb1961.44.1469
    日期:——
    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.

    important intermediates for the synthesis of a variety of steroidal medicines with an α-methyl group or without the methyl group at the C10-position. Although they can be prepared by chemical synthesis or microbial transformation of steroids, their low efficiency and the formation of by-products limit their application. In this study, by investigating the degradation pathway of steroidal C/D rings and
    3aα - H -4α-(3'-丙酸)-5α-羟基-7aβ-甲基六氢-1-茚满酮-δ-内酯(苯乙内酯或HIL)和3aα - H -4α-(3'-丙酸)- 7aβ-甲基六氢-1,5-茚满二酮(HIP)是重要的中间体,用于合成各种甾族药物,其中C10位具有α-甲基或无甲基。尽管它们可以通过类固醇的化学合成或微生物转化来制备,但它们的低效率和副产物的形成限制了它们的应用。在这项研究中,通过研究类固醇C / D环的降解途径并分析转基因分枝杆菌ΔfadD3和ΔfadE30引起的植物甾醇分解代谢中的代谢物(ATCC 6841),鉴定出两个羧酸还原酶基因(car1和car2)与HIP的降解有关。菌株ΔfadD3或ΔfadE30中这两个car基因的失活分别阻止了其他代谢物的产生并增强了HIP或HIL的积累。在制备规模上,重组菌株将植物甾醇以20 g L -1转化为HIP或HIL底物浓度分别达到88%或75
