In this study, we report the synthesis of thiazole Schiff base derivatives (Z1-Z16) and their tyrosinase inhibitory activity, anti-oxidant activities. Mushroom tyrosinase inhibitory assay showed compound Z8 (IC50 = 2.78 ± 0.08 μM) inhibited tyrosinase more than kojic acid (49.39 ± 0.17 μM), and docking study indicated compound Z8 (-7.32 kcal/mol) had stronger binding affinities for tyrosinase than kojic acid (-5.7 kcal/mol). Phenolic hydroxyl group on 4-position (R2) of compound Z8 can form Metal - Acceptor with Cu401. The results of inhibition kinetics studies demonstrated that compound Z8 was mixed type inhibitor. The anti-browning effects manifested compound Z8 expressed satisfactory effects in anti-browning of fresh-cut apples and fresh-cut potato. All the results indicated that thiazole Schiff base derivatives might be promising leading compounds as tyrosinase inhibitors and anti-oxidant agents.

4-Aryl-2-aminothiazoles and 2-aminobenzothiazoles undergo condensation with salicylaldehyde in the presence of piperidine to give the schiff bases II and III, respectively.A similar reaction of 4-aryl-2-aminothiazole methiodides gives the schiff bases 4-aryl-2-(2'-hydroxyaryliminomethyl)thiazole methiodides (IV).Several schiff bases have been condensed with cyclohexanone and thioglycollic acid to furnish 4-aryl-2-(2'-hydroxy-α-substituted benzylamino)thiazoles (V) and 2-(2'-hydroxyphenyl) or naphthyl)-3-(4''-arylthiazol-2''-yl)-4-thiazolidones (VI), respectively.Structure elucidation of the schiff bases has been made on the basis of their elemental analyses, IR and mass spectral data.The biological screening data of the schiff bases and their metal complexes are also presented.
