New series of pyrimidinone-5-carbonitriles 3a–i, 4a–e, 5a–c, 6 and 7 have been synthesized and explored for their activities as anticancer, antibacterial and antifungal agents. Investigation of the anticancer activity revealed that several newly synthesized derivatives displayed potent cytotoxic activity against different cancer cells. Among them, compound 3g was the most potent on the MCF-7, A549 and Caco-2 cell lines (IC50 = 1.42, 1.98 and 9.50 μM, respectively), as compared with 5-fluorouracil (IC50 = 1.71, 10.32 and 20.22 μM, respectively), while compound 3f was found especially effective against MCF-7 and Caco-2 cell lines (IC50 = 1.48 and 16.15 μM, respectively). Furthermore, the antimicrobial evaluation showed that compounds 3f and 3g have potent antibacterial activity against Gram-positive bacteria Staphylococcus aureus (MIC = 4 and 8 μg/mL, respectively) and promising activity against Escherichia coli (IZ. = 19 and 17 mm, respectively). Meanwhile, compound 4b displayed the highest activity toward Bacillus subtilis (MIC = 8 μg/mL). In particular, the results suggested that hydrazone derivatives bearing heterocyclic rings 3f and 3g are good lead compounds for the future design of more potent anticancer or antimicrobial agents.
新合成了一系列嘧啶酮-5-甲腈 3a-i、4a-e、5a-c、6 和 7,并探索了它们作为抗癌、抗菌和抗真菌剂的活性。对抗癌活性的研究表明,几种新合成的衍生物对不同的癌细胞具有很强的细胞毒活性。其中,化合物 3g 对 MCF-7、A549 和 Caco-2 细胞系的作用最强(IC50 = 分别为 1.42、1.98 和 9.50 μM),与 5-氟尿嘧啶(IC50 = 1.71、10.32和20.22 μM)相比,化合物3f对MCF-7和Caco-2细胞株特别有效(IC50 = 分别为1.48和16.15 μM)。此外,抗菌评价结果表明,化合物 3f 和 3g 对革兰氏阳性菌金黄色葡萄球菌具有强效抗菌活性(MIC = 分别为 4 和 8 μg/mL),对大肠杆菌也具有良好的活性(IZ. = 分别为 19 和 17 mm)。同时,化合物 4b 对枯草杆菌的活性最高(MIC = 8 μg/mL)。研究结果特别表明,含有杂环 3f 和 3g 的腙衍生物是未来设计更强抗癌或抗菌剂的良好先导化合物。
