Quinoline derivatives are attracting considerable interest due to their biological importance. In this paper, several 2‐amino‐4‐aryl‐6‐(quinolin‐2‐ylthio)pyridine‐3,5‐dicarbonitrile derivatives are synthesized by adopting a one‐pot reaction of quinoline‐2‐thione, aromatic aldehydes, and malononitrile in the presence of sodium hydroxide in absolute ethanol. The structures of these newly synthesized compounds were determined using different spectroscopic techniques, including elemental analyses, IR, 1H NMR, and MS. The synthesized derivatives were screened for their antimicrobial and cytotoxic activities. Compounds 4a, 4b, 4d, and 4e exhibited promising antimicrobial activity compared to antibacterial and antifungal standard drugs. Additionally, 4f, 4d, and 4g showed potent cytotoxic activity against both MCF‐7 and A549 cells with IC50 values (6.39–9.3 μM). Our molecular docking results of compound 4f prove good binding affinity toward the three tested proteins as Jak2/STATA3 inhibition and are in accordance with the RT‐PCR mRNA expressions of the compound against MCF‐7 cells which downregulated the Jak2 and STAT3 genes, and this may be the proposed mode of action for anti‐breast cancer activity.

新型合成的 6-(喹啉-2-基硫基)吡啶衍生物作为多靶点 JAK2/STAT3 抑制剂的抗微生物和抗增殖活性与分子对接研究

由于其生物学重要性,喹啉衍生物引起了相当大的兴趣。本文采用喹啉-2-硫酮、芳香醛和丙二腈在无水乙醇中的氢氧化钠存在下。这些新合成化合物的结构是使用不同的光谱技术确定的,包括元素分析、IR、1 H NMR 和 MS。筛选合成的衍生物的抗微生物和细胞毒活性。化合物4a4b4d4e与抗菌和抗真菌标准药物相比,表现出有希望的抗菌活性。此外,4f4d4g对 MCF-7 和 A549 细胞均显示出有效的细胞毒活性,IC 50值(6.39–9.3 μM)。我们的化合物4f 的分子对接结果证明了对三种测试蛋白质的良好结合亲和力,如 Jak2/STATA3 抑制,并且与该化合物对 MCF-7 细胞的 RT-PCR mRNA 表达一致,该表达下调 Jak2 和 STAT3 基因,这可能是抗乳腺癌活性的拟议作用模式。
