derivatives connected to a terminal tertiary amine at the alkyl chains of various lengths were prepared. These novel synthetic compounds were assessed for preliminary glucosidase inhibition and anticancer activities in vitro . Potent and selective inhibition was observed among them. Compound 7d (IC 50 = 0.052 mM) showed improved and selective inhibitory activity against β-glucosidase compared to DNJ
制备了一系列在各种长度的烷基链上连接至末端叔胺的N-烷基化脱氧野oji霉素(DNJ)衍生物。这些新的合成化合物进行了初步的葡萄糖苷酶抑制和抗癌活性的体外评价。其中观察到有效和选择性抑制。与DNJ(IC 50 = 0.65 mM)相比,化合物7d(IC 50 = 0.052 mM)对β-葡萄糖苷酶表现出改善的选择性抑制活性。此外,使用Lineweaver-Burk图对酶抑制动力学进行分析,结果表明7d以竞争方式抑制了β-葡萄糖苷酶,这表明7d有望与β-葡萄糖苷酶的活性位点结合。发现化合物8b和8c是α-葡萄糖苷酶的中度和选择性抑制剂。尽管如此,
