The enzyme tyrosinase regulates melanogenesis and skin hyperpigmentation by converting L-3,4-dihydroxyphenylalanine (L-DOPA) into dopaquinone, a key step in the melanin biosynthesis. The present work deals with design and synthesis of various oxindole-based chalcones as monophenolase and diphenolase activity inhibitors of tyrosinase. Among the screened compounds, 4-hydroxy-3-methoxybenzylidene moiety
酪氨酸酶通过将L-3,4-二羟基苯丙氨酸(L-DOPA)转化为多巴醌来调节黑色素生成和皮肤色素沉着,这是黑色素生物合成的关键步骤。本工作涉及设计和合成各种基于羟吲哚的查耳酮作为酪氨酸酶的单酚酶和双酚酶活性抑制剂。在筛选出的化合物中,通过羟吲哚和香草醛的一锅反应制备的带有查尔酮的4-羟基-3-甲氧基亚苄基部分(7)在单酚酶和双酚酶活性测定中显示出最高的抗酪氨酸酶活性,IC50分别为63.37和59.71 µM。在分子对接研究中,在所有对接的配体中,查耳酮7对酪氨酸酶的结合亲和力最高,而估计的结合自由能最低。
