(UV)-induced reactive oxygen species (ROS) is the key regulator of matrix metalloproteinase (MMPs) expression. In this study, a series of Caffeic acid phenethyl ester (CAPE) analogues were synthesized by conjugating the group VI elements (selenium, sulfur, oxygen)-containing aliphatic alcohols to polyphenolic acids. Their biological activities were evaluated by in vitro testing of their radical scavenging
在皮肤光老化过程中,紫外线(UV)诱导的活性氧(ROS)是基质金属蛋白酶(MMPs)表达的关键调节因子。在这项研究中,通过将含有 VI 族元素(硒、硫、氧)的脂肪醇与多酚酸结合,合成了一系列咖啡酸苯乙酯 (CAPE) 类似物。通过体外测试其自由基清除活性、ABTS [2,2'-azinobis-(3-ethyl-benzothiazoline-6-sulfonic acid)] 自由基和对基质金属蛋白酶-1 (MMP) 的抑制作用来评估它们的生物活性-1)人真皮成纤维细胞皮肤细胞的胶原蛋白降解活性和细胞毒性。我们的结果表明,这些化合物显示出适度的抗自由基、有效的 MMP-1 抑制和低细胞毒活性。
