A new series of thiobarbituric (thiopyrimidine trione) enamine derivatives and its analogues barbituric acid derivatives was synthesised, characterised, and screen for in vitro evaluation of α-glucosidase enzyme inhibition and anti-glycation activity. This series of compounds were found to inhibit α-glucosidase activity in a reversible mixed-type manner with IC50 between 264.07 ± 1.87 and 448.63 ± 2
合成,表征和表征了一系列新的硫代巴比妥酸(硫代嘧啶三酮)烯胺衍生物及其类似物巴比妥酸衍生物,用于体外评估α-葡萄糖苷酶的抑制作用和抗糖化活性。发现该系列化合物以可逆的混合型方式抑制α-葡萄糖苷酶活性,IC50在264.07±1.87和448.63±2.46 µM之间。分子对接研究表明3g,3i,3j和5的化合物位于α-葡萄糖苷酶的活性位点附近,该活性位点可能覆盖了活性囊,从而抑制了底物与酶的结合。硫嘧啶三酮衍生物还抑制晚期糖基化终产物(AGEs)的产生,后者会导致糖尿病的长期并发症。而化合物3a-k,5
