relationship (SAR) studies suggest that hydroxyl groups in the 2/5-position of para-benzoquinone are very important, and long-chain substituents in the 3-position are highly preferred. Moreover, the inhibition mechanism and kinetics studies reveal that all of 10d, 12d, 15d, and embelin are reversible and mixed-type inhibitors. Furthermore, docking experiments were carried out to study the interactions
Embelin是从Myrsinaceae家族的Embelia ribes(Burm.f.)分离的天然对苯醌。在这项研究中,首次发现它对α-葡萄糖苷酶具有有效的抑制活性(IC50 = 4.2μM)。然后,设计,制备和评估了四个系列的新型栓塞衍生物,并通过α-葡萄糖苷酶抑制试验进行了评估。结果表明,合成的大多数栓蛋白衍生物是有效的α-葡萄糖苷酶抑制剂,IC50值在微摩尔水平,尤其是10d,12d和15d,其IC50值分别为1.8、3.3和3.6μM。结构-活性关系(SAR)研究表明,对苯醌的2/5位上的羟基非常重要,而3位上的长链取代基则是首选。此外,抑制机理和动力学研究表明,所有10d,12d,15d和embelin都是可逆的混合型抑制剂。此外,进行了对接实验以研究10d和15d与α-葡萄糖苷酶之间的相互作用。
