properties against the highly invasive prostate cancer. To further optimize the activity of PMHs, various ligand‐based strategies were used including the extension of the structure, structural simplification, linker extension, and computer‐assisted CoMFA (Comparative Molecular Field Analysis) results. These strategies yielded thirty 2nd‐generation PMHs, designed based on the 1st‐generation PMHs, such
前列腺癌是西方国家男性中最常见的癌症形式之一。天然产物被证明是分子多样性的无与伦比的来源。4-(羟基苯亚甲基)乙内酰脲 (PMH; 1), (5Z)-5-(4-hydroxybenzylidene)imidazolidine-2,4-dione,从红海海绵半真菌阿拉比卡中分离出来,最近显示出连接复合物的稳定性,抗-体外和体内的侵入性和抗转移活性。相关的合成类似物,(5Z)-5-[4-(乙基硫烷基)苯亚甲基]咪唑烷-2,4-二酮 (2),显示出对高侵袭性前列腺癌的体内抗转移特性提高了数倍。为了进一步优化 PMH 的活性,使用了各种基于配体的策略,包括结构扩展、结构简化、接头扩展、和计算机辅助的 CoMFA(比较分子场分析)结果。这些策略产生了 30 种基于第一代 PMH 设计的第二代 PMH,例如 1 和 2。选择伤口愈合试验来评估这些新 PMH 对 PC-3 细胞系的体外抗迁移潜力. 确定了几种活性
