Twenty‐seven 1,5‐disubstituted‐pyridin‐2(1H)‐one derivatives were synthesized and evaluated for their anti‐cancer and anti‐fibrosis activity by A549 and NIH3T3 cell viability assays, respectively. To study the selectivity between the cancer and fibrosis cell lines, pharmacophore models (F1–F4) were built in advance for compounds with pyridin‐2(1H)‐one scaffold, which revealed the relationship between
合成了 27 种 1,5-二取代吡啶-2(1H)-one 衍生物,并分别通过 A549 和 NIH3T3 细胞活力测定评估了它们的抗癌和抗纤维化活性。为了研究癌症和纤维化细胞系之间的选择性,预先建立了带有吡啶-2(1H)-one 支架的化合物的药效团模型(F1-F4),揭示了芳香亚位点 F4 占据之间的关系和有效的抗癌活性。本文还报告了所有目标化合物的结构和抗癌活性之间的关系:1-Phenyl-5-((m-tolylamino)methyl)pyridine-2(1H)-one (22) 显示出效力和选择性 (IC50 = 0.13 mM) 通过抑制翻译起始,特别是通过 eIF3a 抑制,对 A549 细胞系,
