investigated the reversibility of the thia-Michael reaction of 1,5-bis(3,5-bis(methoxymethoxy)phenyl)-1,4-pentadiene-3-one, named GO-Y030 which is the most potent cytotoxic C5-curcuminoid, using spectroscopic methods. A panel of GO-Y030-bis-thiol-adducts were synthesized and the structure–reactivity relationship regarding the retro thia-Michael reaction as well as the cell growth inhibitory activity against
C 5-姜黄素类[又名双(芳基亚甲基)丙酮]是姜黄素类似物,其具有反应性交联的二烯酮结构,对于引发细胞毒性是必不可少的。为了深入了解C 5-姜黄素的作用方式,我们研究了1,5-双(3,5-双(甲氧基甲氧基)苯基)-1,4-戊二烯-3-的硫-迈克尔反应的可逆性一种,使用光谱学方法命名为GO-Y030,它是最有效的细胞毒性C 5-姜黄素。合成了一组GO-Y030-双-硫醇加合物,并评估了与逆硫-迈克尔反应的结构反应关系以及对人结肠癌HCT116的细胞生长抑制活性。一些C 5-姜黄素硫醇加合物显示出与GO-Y030相当的细胞毒性,证明了它们作为前药的潜在用途。这些结果暗示,C 5-姜黄素类化合物通过可逆的thia-Michael反应与各种生物硫醇共价相互作用而引起细胞毒性。
