Abstract
The current study aimed to design and synthesize a novel series of fluorophenyl-isoxazole-carboxamide derivatives and evaluate their antiproliferative activities. Anticancer activities of the novel compounds were evaluated by MTS assay against four cancer cell lines, including liver (Hep3B, HepG2), cervical (HeLa), and breast (MCF-7), and α-fetoprotein tumor marker, cell cycle analysis, and annexin V tests. Chemo-informatics analysis showed that all synthesized derivatives 2a–2f obeyed Lipinski’s rule. Compound 2f was the most potent compound against Hep3B and Hep-G2 cancer cell lines with IC50 values of 5.76 and 34.64 µg/mL, respectively. Moreover, compounds 2a–2c and 2e showed potent inhibitory activity against Hep3B with an IC50 value range of 7.66–11.60 µg/mL. Hep3B secretions of α-fetoprotein (α-FP) results showed that compound 2f reduced the secretion of Hep3B to 168.33 ng/mL and compound 2d reduced the secretion to value approximately 598.33 ng/mL, in comparison with untreated cells’ value of 1116.67 ng/mL. Furthermore, cell cycle analysis showed that the 2f compound induced arrest in the G2-M phase in 6.73% of the total cells and that was lower than the activity of the positive control doxorubicin (7.4%). Moreover, 2b and 2f compounds reduced the necrosis rate of Hep3B to 4-folds and shifted the cells to apoptosis.
当前研究旨在设计合成一系列新型氟苯基异噁唑羧酰胺衍生物,并评估它们的抗增殖活性。新化合物的抗癌活性通过MTS法对包括肝脏(Hep3B,HepG2)、子宫颈(HeLa)和乳腺(MCF-7)在内的四种癌细胞系进行评估,以及α-胎蛋白肿瘤标记物、细胞周期分析和V型连接素测试。化学信息学分析表明,所有合成的衍生物2a-2f都符合Lipinski的规则。化合物2f对Hep3B和Hep-G2癌细胞系具有最强的活性,IC50值分别为5.76和34.64 µg/mL。此外,化合物2a-2c和2e对Hep3B表现出强大的抑制活性,IC50值范围为7.66-11.60 µg/mL。Hep3B分泌的α-胎蛋白(α-FP)结果表明,化合物2f将Hep3B的分泌降低到168.33 ng/mL,化合物2d将分泌降低到约598.33 ng/mL,而未经处理的细胞值为1116.67 ng/mL。此外,细胞周期分析显示,化合物2f使总细胞中的6.73%在G2-M期停滞,低于阳性对照多柔比星(7.4%)的活性。此外,化合物2b和2f将Hep3B的坏死率降低了4倍,并将细胞转变为凋亡。
