  • Hydnocarpin-Type Flavonolignans: Semisynthesis and Inhibitory Effects on <i>Staphylococcus aureus</i> Biofilm Formation

    utilizing this new method. The synthesis is based on the two-step transformation of the readily available flavonolignans from milk thistle (Silybum marianum), accessible by isolation from the commercial extract silymarin. The first step relies on the regioselective formylation of the C-3 hydroxy group of the dihydroflavonol-type precursor using the Vilsmeier–Haack reagent, followed by formic acid elimination
    开发并优化了一种新的,高效的,通用的蛇皮草型黄酮木聚糖半合成法,从而实现了按克规模生产的hydnocarpin D(2)。此外,光学纯的木犀草异构体[(10 R,11 R)-木犀草素(1a),(10 R,11 R)-木犀草素D(2a)和(10 S,11 S)-木犀草素D(2b)的合成)]以及异羟卡巴汀(8)的合成,是首次使用这种新方法实现的。合成基于乳蓟中容易获得的黄酮木聚糖的两步转化(水飞蓟),从商用的提取水飞蓟素隔离访问。第一步依靠使用Vilsmeier-Haack试剂对二氢黄酮型前体的C-3羟基进行区域选择性甲酰化,然后在第二步中用三乙胺消除甲酸。合成的化合物是金黄色葡萄球菌生物膜形成的有效抑制剂,其中(10 S,11 S)-hydnocarpin D(2b)是最有效的抑制剂。此外,测试了葡萄糖对生物膜形成的影响,并且葡萄糖降低了2b的生物膜抑制活性。此外,2b增加了葡萄球菌的敏感性。金黄色
  • Synthesis and Structures of Regioisomeric Hydnocarpin-Type Flavonolignans
    作者:Nathan R. Guz、Frank R. Stermitz
    DOI:10.1021/np000166d
    日期:2000.8.1
    Flavonolignans represent natural compounds whose biosynthesis presumes a radical coupling of a ring B catecholic flavonoid with a molecule of coniferyl alcohol or an analogue. Many natural flavonolignans can exist as regioisomers, depending on how the coupled coniferyl alcohol moiety orients to the flavonoid. These regioisomers are often difficult to separate and have virtually identical NMR spectra. Structural assignments for some have changed with time or have been given without proof. We here report syntheses of both regioisomers of the flavonolignan hydnocarpin and one isomer of a plant isolate previously known as 5'-methoxyhydnocarpin. This isomer, here renamed 5'-methoxyhydnocarpin-D, was recently shown to be a potent inhibitor of a Staphylococcus aureus multidrug resistant efflux pump.

    Various Mitsunobu conditions were investigated for a series of flavonolignans (silybin A, silybin B, isosilybin A, and silychristin A) to achieve either selective esterification in position C-23 or dehydration in a one-pot reaction yielding the biologically important enantiomers of hydnocarpin D, hydnocarpin and isohydnocarpin, respectively. This represents the only one-pot semi-synthetic method to
