Anti-melanogenesis screening of 47 synthesized curcumin-like diarylpentanoid analogues was performed to show that some had a potent inhibitory effect on the melanogenesis in B16 melanoma cells. Their actions were considered to be mostly due to tyrosinase inhibition, tyrosinase expression inhibition, and melanin pigment degradation. The structure–activity relationships of those curcumin-like diarylpentanoid analogues which inhibited the melanogenesis and tyrosinase activity were also discussed. Of those compounds assayed, (2E,6E)-2,6-bis(2,5-dimethoxybenzylidene)cyclohexanone showed the most potent anti-melanogenesis effect, the mechanism of which is considered to be the degradation of the melanin pigment in B16 melanoma cells, affecting neither the tyrosinase activity nor tyrosinase expression.
对47种合成的姜黄素样二芳基戊烷类类似物进行了抗黑色素生成筛选,结果显示其中一些对B16黑色素瘤细胞的黑色素生成具有强抑制作用。这些作用主要被认为是通过抑制酪氨酸酶活性、抑制酪氨酸酶表达和降解黑色素色素实现的。还讨论了那些抑制黑色素生成和酪氨酸酶活性的姜黄素样二芳基戊烷类类似物的结构-活性关系。在测试的化合物中,(2E,6E)-2,6-双(2,5-二甲氧基苄叉)环己酮显示了最强的抗黑色素生成效果,其机制被认为是在B16黑色素瘤细胞中降解黑色素色素,既不影响酪氨酸酶活性也不影响酪氨酸酶表达。
