-2-thioxodihydropyrimidine-4,6(1H,5H)-dione (4g) is the most potent antityrosinase agents with an IC50 value of 23.90 ± 0.08 μM. It showed even better inhibitory activity than kojic acid. The results of kinetic and molecular docking studies demonstrated that compound 4g acts as a noncompetitive inhibitor and can bind to some amino acids such as His263 and Val283 of the active site through Pi–alkyl
新的 2-亚苄基硫代巴比妥酸-(苄氧基苯基) 衍生物被设计、合成和评估为酪氨酸酶抑制剂。产品可分为两类:4-羟基苯甲醛衍生物和香草醛衍生物。一些4-羟基苯甲醛衍生物显示出显着的抑制活性,而所有香草醛衍生物都没有抑制活性。似乎内部芳环上甲氧基的存在阻止了配体-酶的相互作用。根据酪氨酸酶抑制试验,5-(4-([4-Methylbenzyl]oxy)benzylidene)-2-thioxodihydropyrimidine-4,6(1H,5H)-dione ( 4g ) 是最有效的抗酪氨酸酶药物,IC 50值为 23.90 ± 0.08 μM。它显示出比曲酸更好的抑制活性。动力学和分子对接研究的结果表明,化合物4g作为一种非竞争性抑制剂,可以通过 Pi-烷基和 Pi-Pi 相互作用与活性位点的某些氨基酸如 His263 和 Val283 结合,并通过氢键。计算机吸附、分布、代谢、排泄和毒性(A
