To identify novel therapeutic agents to treat cancer, we synthesized a series of diaryl ether derivatives. Structure–activity relationship studies revealed that the presence of a chlorine or hydroxyl at the para-position on the phenyl ring (5h or 5k) significantly enhanced antitumor activity. Compound 5h had stronger growth inhibitory activity in HepG2, A549, and HT-29 cells than compound 5k, with IC50 values of 2.57, 5.48, and 30.04 μM, respectively. Compound 5h also inhibited the growth of other cells lines, including Hep3B, PLC/PRF5, SMMC-7721, HeLa, and A375, with IC50 values of 2.76, 4.26, 29.66, 18.86, and 10.21 μM, respectively. The antitumor activity of compound 5h was confirmed by a colony forming assay. Further, our results indicated that the antitumor activity of compound 5h may be mediated by enhancing expression of p21 and cl-caspase3, and leading to apoptosis of cancer cells.
为了发现新的抗癌药物,我们合成了一系列二苯醚衍生物。结构-活性关系研究表明,在苯环的对位引入氯或羟基(如5h或5k)显著增强了抗肿瘤活性。化合物5h在HepG2、A549和HT-29细胞中的生长抑制活性强于化合物5k,其IC50值分别为2.57、5.48和30.04 μM。化合物5h还能抑制其他细胞系的生长,包括Hep3B、PLC/PRF5、SMMC-7721、HeLa和A375,其IC50值分别为2.76、4.26、29.66、18.86和10.21 μM。化合物5h的抗肿瘤活性通过集落形成实验得到了验证。进一步的结果表明,化合物5h的抗肿瘤活性可能是通过上调p21和cl-caspase3的表达,并诱导癌细胞凋亡来介导的。
