3-b]pyridine-2-carboxamides 1a,b with different reagents. All new compounds were evaluated against five bacterial and five fungal strains. Many of the target compounds showed significant antimicrobial activity. In addition, the new derivatives were further subjected to cytotoxicity evaluation against HepG-2 and MCF-7 cancer cell lines. The most potent cytotoxic candidates (3a, 4a, 5a, 6b, 8b and 9b)
除了癌症患者数量的持续增加之外,抗菌药物耐药性的风险日益增加,对全球健康构成了巨大威胁,这需要加紧努力发现新的生物活性化合物作为抗菌剂和抗癌剂。因此,通过3-氨基-噻吩并[2,3-b]吡啶-2-甲酰胺1a,b与不同试剂的环化反应合成了一组新的吡啶并噻吩并嘧啶衍生物2a,b–9a,b。所有新化合物均针对五种细菌和五种真菌菌株进行了评估。许多目标化合物表现出显着的抗菌活性。此外,新衍生物还进一步针对HepG-2和MCF-7癌细胞系进行了细胞毒性评估。最有效的细胞毒性候选药物(3a、4a、5a、6b、8b 和 9b)作为 EGFR 激酶抑制剂进行了检查。还进行了分子对接研究来探索这些衍生物在EGFR-PK活性位点的结合模式。化合物 3a、5a 和 9b 显示出广谱抗菌活性,MIC 范围为 4–16 µg/mL,并且具有有效的细胞毒活性,IC50 范围为 1.17–2.79 µM。此外,它们还具有针对
