Syntheses of 2-methoxyestradiol (1) and eugenol (6) template based conformationally flexible and rigid diarylpropenes, 14(a–l) and 20(a–e), as nonsteroidal anticancer agents have been performed. The synthesized compounds were evaluated for their anticancer activity in in vitro using a panel of human cancer cell lines viz. MCF-7, A549, DU 145, KB and MDA-MB-231by SRB assay. Compounds 14i, 14k and 15a showed significant anticancer activity at IC50 between 10.27 μM to 27.91 μM in different cancer cell lines. The most active molecule, 14k, inhibited proliferation of cells by inducing apoptosis and arresting the cell cycle at the G2/M phase. In vitro toxicity of these compounds (14i, 14k and 15a) in healthy hepatic monocyte (THP-1) cells showed high selectivity of compounds towards cancerous vs. healthy cells.
基于
2-甲氧基雌二醇(1)和
丁子香酚(6)模板,合成了构象灵活和刚性的二芳基
丙烯类化合物14(a–l)与20(a–e),作为非甾体
抗肿瘤药物。采用SRB法评估了这些合成化合物在体外对人癌
细胞系MCF-7、A549、DU 145、KB和
MDA-MB-231的抗肿瘤活性。化合物14i、14k和15a在不同癌
细胞系中显示显著的抗肿瘤活性,IC50值介于10.27 μM至27.91 μM之间。活性最高的分子14k通过诱导凋亡和阻滞细胞周期于G2/M期来抑制细胞增殖。在正常肝单核细胞(THP-1)中进行的体外毒性测试显示,这些化合物(14i、14k和15a)对癌细胞与健康细胞具有高度的选择性。
