synthesized aurone derivatives were found as potent tyrosinase inhibitors relative to the standard kojic acid (IC50 = 16.69 ± 2.81 μM) and the compound 39 inhibited tyrosinase non-competitively (Ki = 11.8 μM) by forming an enzyme-inhibitor complex. The binding modes of these molecules were ascribed through molecular docking studies against tyrosinase protein (PDB ID: 2Y9X). The quantitative structure-activity
摘要 酪氨酸酶在黑色素生物合成和水果和蔬菜的酶促褐变中起着重要作用。为了发现有效的酪氨酸酶抑制剂,进行了本研究。在此背景下,通过各种光谱技术(包括红外、紫外、 1 H 和13 C-NMR 以及质谱)设计、合成并阐明了合成傲酮衍生物26-50的结构。筛选了目标化合物26-50的抗酪氨酸酶抑制潜力,并通过Lineweaver-Burk图分析了动力学机制。所有目标化合物均表现出良好至优异的 IC 50值,范围为 7.12 ± 0.32 μM 至 66.82 ± 2.44 μM。这些合成的橙酮衍生物被发现是相对于标准曲酸的有效酪氨酸酶抑制剂(IC 50 = 16.69 ± 2.81 μM),并且化合物39通过形成酶抑制剂复合物非竞争性抑制酪氨酸酶(K i = 11.8 μM)。这些分子的结合模式是通过针对酪氨酸酶蛋白(PDB ID:2Y9X)的分子对接研究来确定的。定量构效关系研究显示26-50个结构与其抗酪氨酸酶活性(IC
