    Characteristic alkaline catalyzed degradation of kotalanol, a potent α-glucosidase inhibitor isolated from Ayurvedic traditional medicine Salacia reticulata, leading to anhydroheptitols: another structural proof
    摘要:
    Stereochemical structure of kotalanol (2), a highly potent a-glucosidase inhibitor isolated from an Ayurvedic traditional medicine Salacia reticulata, was proved by alkaline catalyzed degradation of natural kotalanol (2), in which characteristic stereospecific cyclization of the degradative side chain leading to anhydroheptitols (10 and 11) was involved.

  • Synthesis of a biologically active isomer of kotalanol, a naturally occurring glucosidase inhibitor

    The syntheses of an isomer of kotalanol, a naturally occurring glucosidase inhibitor, and of kotalanol itself are described. The target compounds were synthesized by nucleophilic attack of PMB-protected 1,4-anhydro-4-thio-d-arabinitol at the least hindered carbon atom of two 1,3-cyclic sulfates, which were synthesized from d-mannose. Methoxymethyl ether and isopropylidene were chosen as protecting
    描述了天然存在的葡糖苷酶抑制剂的果糖醇的异构体和果糖醇本身的合成。目标化合物通过亲核攻击合成PMB保护的1,4-脱水-4-硫代- d -arabinitol在两个1,3-环硫酸酯,将其从合成的至少受阻碳原子d甘露糖。选择甲氧基甲基醚和异亚丙基作为保护基。后一组对于确保偶联产物的容易的脱保护以一步一步的顺序以产生邻苯二酚和其异构体是至关重要的。kotalanol的立体异构体,具有在C-6'立体中心具有相反立体化学,抑制肠麦芽糖酶人类葡糖淀粉酶(ntMGAM)N-末端催化结构域与ķ我值为0.20±0.02μM; 相比之下,可可醇的K i值为0.19±0.03μM。结果表明,在C-6'处的构型对于针对该酶的抑制活性是无关紧要的。

    Salacinol and ponkoranol homologues, derivatives thereof and methods of synthesizing and using said homologies and derivatives. The derivatives include stereoisomers, de-O-sulfonated compounds and congeners of the naturally occurring homologues. Some of the derivatives exhibit enhanced glucosidase inhibitory bioactivity in comparison to the naturally occurring compounds which have been isolated from salacia reticulata.
