A novel kojic acid derivative containing a trolox moiety, (±)-5-hydroxy-4-oxo-4H-pyran-2-yl methyl 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylate (3a), was synthesized. The two biologically active compounds, namely, kojic acid and trolox, were conjugated via an ester bond as they are expected to behave synergistically. The antioxidant activity and the tyrosinase inhibitory activity of this novel
一种新型的曲酸衍生物,其含有trolox部分,(±)-5-羟基-4-氧代-4 H-吡喃-2-基甲基6-羟基-2,5,7,8-四甲基苯并-2-羧酸酯(3a),已合成。两种生物活性化合物,即曲酸和trolox,通过酯键共轭,因为它们预期具有协同作用。评价了该新型曲酸衍生物对黑素生成的抗氧化活性和酪氨酸酶抑制活性。化合物3a表现出强大的酪氨酸酶抑制活性和自由基清除活性。有限的结构-活性关系(SAR)研究表明,酪氨酸酶抑制活性可能起源于曲酸部分,自由基清除活性可能是由于trolox的酚羟基所致。在基于细胞的测定中,化合物3a还表现出有效的脱色活性。有限的SAR研究表明,3a的脱色活性可能是由于曲酸和其trolox部分的协同活性。
