describe the design, synthesis and biological activities of 2-(substituted phenyl)thiazolidine-4-carboxylic acid derivatives as novel tyrosinase inhibitors. The target compounds 2a-2j were designed and synthesized from the structural characteristics of N-phenylthiourea, tyrosinase inhibitor and tyrosine, and l-DOPA, the natural substrates of tyrosinase. Among them, (2R/S,4R)-2-(2,4-dimethoxyphenyl)
在这里,我们描述2-(取代的苯基)噻唑烷-4-羧酸衍生物作为新型酪氨酸酶抑制剂的设计,合成和生物学活性。根据N-苯基硫脲,酪氨酸酶抑制剂和酪氨酸的结构特征以及酪氨酸酶的天然底物1-DOPA的结构特征设计和合成目标化合物2a-2j。其中,(2R / S,4R)-2-(2,4-二甲氧基苯基)噻唑烷-4-羧酸(2g)在20μM蘑菇酪氨酸酶的1-DOPA氧化酶活性上产生最大的抑制作用达66.47%。酪氨酸酶抑制的动力学分析表明2g是竞争性抑制剂。我们预测了酪氨酸酶的三级结构,并模拟了蘑菇酪氨酸酶与2g的对接。这些结果表明2g与酪氨酸酶的结合亲和力高。还,2g有效抑制了用α-MSH处理的B16细胞中的酪氨酸酶活性并降低了黑色素水平。这些数据强烈表明2g可通过抑制酪氨酸酶活性来抑制黑色素的产生。
