摘要
以2,4-噻唑烷二酮和取代芳香醛为起始原料,反应得到一系列2,4-噻唑烷二酮衍生物,并对所合成化合物进行了抑制酪氨酸酶活性测试,结果表明化合物均有一定的抑制酪氨酸酶活性,化合物1((E)-5-(3-氯苯亚甲基)噻唑烷-2,4-二酮)和化合物2((E)-5-(2,4-二氯苯亚甲基)噻唑烷-2,4-二酮)活性强于阳性对照曲酸,其中化合物1表现出最好的抑制酪氨酸酶活性,其IC_(50)值为18. 43μmol/L。优选化合物1进行了抑制机理探讨,结果表明其为不可逆抑制剂,同时对化合物1进行了分子对接研究。
A series of 2,4-thiazolidinedione derivatives were synthesized from 2,4-thiazolidinedione and aromatic substituted aldehydes. The tyrosinase inhibitory activity of the synthesized compounds was tested. The results indicate that all the synthesized compounds have some tyrosinase inhibitory activity. Compound 1((E)-5-(3-chlorobenzomethylene) thiazolidine-2,4-dione) and compound 2((E)-5-( 2,4-dichlorobenzomethylene)thiazolidine-2,4-dione) activity are stronger than the other compounds,especially,compound 1 shows more potent inhibitory effect than the positive control kojic acid,its IC_(50) value is 18. 43μmol/L. The inhibitory mechanism of compound 1 was studied,and the result showed that it was an irreversible inhibitor. Molecular docking study of compound 1 was also carried out.
