To that end, we designed, prepared and biologically evaluated 42 new analogs and derivatives of PIB-SOs namely 1-(4-(phenylthio)phenyl)imidazolidin-2-ones (TPIs), 1-(4-(phenylthio)phenyl)ureas (TPUs), 1-ethyl-3-(4-(phenylthio)phenyl)thioureas (TPTs) and N-(4-(phenylthio)phenyl)butyramides (TPAs). The antiproliferative activity of the most potent derivatives on HT-1080, HT-29, M21 and MCF7 human cancer
微管和抗微管剂在癌症化疗中很重要。事实上,微管对于在细胞分裂和细胞形态发生过程中形成有丝分裂纺锤体是必不可少的。在这项研究中,我们修改了名为 4-(2-oxoimidazolidin-1-yl)苯磺酸苯酯 (PIB-SOs) 的新型抗微管剂家族的结构部分,以评估取代 1) PIB 磺酸盐桥的效果-SOs 通过硫醚桥和 2) 咪唑啉-2-one 基团通过各种取代的脲部分、乙基硫脲或丁酰胺。为此,我们设计、制备和生物学评估了 42 种新的 PIB-SO 类似物和衍生物,即 1-(4-(苯硫基)苯基)咪唑啉-2-酮 (TPI)、1-(4-(苯硫基)苯基)脲 (TPU)、1-乙基-3-(4-(苯硫基)苯基)硫脲 (TPT) 和N-(4-(苯硫基)苯基)丁酰胺 (TPA)。最有效的衍生物对 HT-1080、HT-29、M21 和 MCF7 人类癌细胞系的抗增殖活性在纳摩尔到低微摩尔范围内。最有效的 TPU
