Kojic acid is a natural tyrosinase inhibitor that has been clinically used to cure hyperpigmentation in humans. However, kojic acid as a hydrophilic small-molecule has deficient inhibitory activity and stability. In this current work, a new series of kojic acid derivatives, 4a–h bearing 2-amino-5-mercapto-1,3,4-thiadiazole, were synthesized using TBTU as the catalyst, and their chemical structures
曲酸是一种天然酪氨酸酶抑制剂,已在临床上用于治疗人类色素沉着过度。然而,曲酸作为亲水性小分子,其抑制活性和稳定性不足。在本工作中,以 TBTU 为催化剂,合成了一系列新的曲酸衍生物 4a-h,其中含有 2-氨基-5-巯基-1,3,4-噻二唑,并通过光谱方法对其化学结构进行了表征。 . 体外评价了合成化合物对蘑菇酪氨酸酶的抑制活性,一些衍生物显示出有效的抗酪氨酸酶活性。特别是化合物4g (IC 50 =10.71 ± 2.47 µM) 和4h (IC 50=18.62 ± 3.05 µM) 与参比化合物曲酸 (IC 50 =23.14 µM) 相当。对接研究与实验结果吻合较好,表明化合物4g与酪氨酸酶活性位点完全相互作用,结合能和模式适当。
