of plant-derived foods. Tyrosinase inhibitors are very important in medicine, cosmetics and agriculture. In order to develop more active and safer tyrosinase inhibitors, an efficient approach is to modify natural product scaffolds. In this work, two series of novel tyrosinase inhibitors were designed and synthesized by the esterification of cinnamic acid derivatives with paeonol or thymol. Their inhibitory
酪氨酸酶是黑色素生物合成的关键酶,也参与植物性食品的酶促褐变。酪氨酸酶抑制剂在医药、化妆品和农业中非常重要。为了开发活性更高、更安全的酪氨酸酶抑制剂,一种有效的方法是对天然产物支架进行修饰。本工作通过肉桂酸衍生物与丹皮酚或百里酚的酯化反应设计并合成了两个系列的新型酪氨酸酶抑制剂。评估了它们对蘑菇酪氨酸酶的抑制作用。大多数这些化合物(IC 50:2.0 至 163.8 μM)被发现是比其母体化合物(IC 50:121.4 至 5925.0 μM)更好的抑制剂。其中,( E )-2-乙酰基-5-甲氧基苯基-3-(4-羟基苯基)丙烯酸酯( 5a )、( E )-2-乙酰基-5-甲氧基苯基-3-(4-甲氧基苯基)丙烯酸酯( 5g ) ( E )-2-异丙基-5-甲基苯基-3-(4-羟基苯基)丙烯酸酯( 6a )表现出很强的抑制活性;与阳性对照曲酸(IC 50 :32.2 μM)相比, IC 50值分别为2
