从地蚕(Stachys geobombycis C.)的根中分得两个新化合物geobomlin A(1)和geobomlin B(2)。Y.吴主要通过二维NMR和MS数据分析确定结构。Geobomlin B对α-葡萄糖苷酶显示出中等抑制活性,IC 50 = 248.77 μM。我们还确定了geobomlin B对α-葡萄糖苷酶的抑制作用机制,并建立了竞争性抑制模式。对接研究证实了我们关于geobomlin B α-葡萄糖苷酶抑制特性的结果。
Two new compounds geobomlin A (1) and geobomlin B (2) were isolated from the roots of Stachys geobombycis C. Y. Wu. Structural determinations were established principally by two-dimensional NMR and MS data analyses. Geobomlin B showed moderate inhibitory activity against α-glucosidase with IC50 = 248.77 μM. We have also determined the mechanism by which geobomlin B elicit its inhibitory effect on α-glucosidase, for which we have established a competitive inhibition mode. Docking studies confirmed our results on geobomlin B α-glucosidase inhibitory properties.
