Isoxerophilusins A () and B (), two unprecedented diterpene heterodimers biogenetically from -atisanes and abietanes, were isolated from the rhizomes of . Their structures were determined by extensive spectroscopic analysis and single-crystal X-ray diffraction. Selective esterification of generated 11 new derivatives. All derivatives showed excellent -glucosidase inhibitory activity in comparison to acarbose. Compounds and demonstrated significant inhibition against -glucosidase with IC values of 4.92 and 3.83 M, respectively.
异沙蚕毒素 A()和 B(),两个前所未有的二萜杂二聚体,来源于-蒎烯和贝壳杉烯,从 Isoxerophilus 属植物的根茎中分离得到。它们的结构通过广泛的光谱分析和单晶 X 射线衍射确定。对 进行选择性酯化得到 11 个新衍生物。与阿卡波糖相比,所有衍生物均显示出优异的 -葡萄糖苷酶抑制活性。化合物和表现出对 -葡萄糖苷酶的显著抑制作用,IC 值分别为 4.92 和 3.83 μM。
