A number of 2,3-diarylquinoline derivatives were synthesized and evaluated for antiproliferative activities against the growth of six cancer cell lines including human hepatocellular carcinoma (Hep G2 and Hep 3B), non-small cell lung cancer (A549 and H1299), and breast cancer (MCF-7 and MDA-MB-231) cell lines. The preliminary results indicated that 6-fluoro-2,3-bis4-[2-(piperidin-1-yl)ethoxy]phenyl}quinoline (16b) was one of the most active compounds against the growth of Hep 3B, H1299, and MDA-MB-231 with a GI50 value of 0.71, 1.46, and 0.72 μM respectively which was more active than tamoxifen. Further investigations have shown that 16b induced cell cycle arrest at G2/M phase followed by DNA fragmentation via an increase in the protein expression of Bad, Bax and decrease in Bcl-2, and PARP which consequently cause cell death.
合成了多种2,3-二芳基喹啉衍生物,并评估其对六种癌细胞系的增殖抑制活性,包括人类肝细胞癌(Hep G2和Hep 3B)、非小细胞肺癌(A549和H1299)以及乳腺癌(MCF-7和MDA-MB-231)细胞系。初步结果表明,6-氟-2,3-双4-[2-(哌啶-1-基)乙氧]苯基}喹啉(16b)是对Hep 3B、H1299和MDA-MB-231增殖抑制活性最强的化合物之一,其GI50值分别为0.71、1.46和0.72 μM,活性优于他莫昔芬。进一步研究显示,16b通过增加Bad、Bax的蛋白表达并降低Bcl-2和PARP的水平,诱导细胞在G2/M期周期停滞,随后导致DNA片段化,最终引起细胞死亡。
