Novel sulfonamides 3–19 with a biologically active 3,4-dimethoxyphenyl moiety were designed and synthesized. The structures of the synthesized compounds were established using elemental analyses, IR, 1H-NMR, 13C-NMR spectral data and mass spectroscopy. All the synthesized compounds were evaluated for their in vitro anticancer activity against four cancer cell lines, namely human hepatocellular carcinoma (HepG2), human medulloblastoma (Daoy), human cervical cancer (HeLa), and human colon cancer (HT-29), by using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and dasatinib as the reference drug. Among the tested derivatives, compounds 4, 10, 16, and 19 showed good activity as cytotoxic agents. The most active derivatives were evaluated for their ability to inhibit vascular endothelial growth factor receptor (VEGFR)-2. Compounds Z-4-(3-(3,4-dimethoxyphenyl)-3-oxoprop-1-enylamino)-N-(5-methyl-1,3,4-thiadiazol-2-yl)-benzenesulfonamide 10 and Z-4-(3-(3,4-dimethoxyphenyl)-3-oxoprop-1-enylamino)-N-(1H-indazol-6-yl)-benzenesulfonamide 19 were more active as VEGFR-2 inhibitors than dasatinib. Molecular docking of the most active derivatives on the active site of VEGFR-2 revealed that compound 19 exhibited favorable and promising results.
设计并合成了含生物活性3,4-二甲氧基苯基部分的新型磺胺类化合物3–19。通过元素分析、红外光谱、氢核磁共振、碳核磁共振光谱和质谱数据确定了合成化合物的结构。利用3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四唑啉溴(MTT)试验和达沙替尼作为参比药物,评估了所有合成化合物对四种癌细胞系的体外抗癌活性,即人肝细胞癌(HepG2)、人髓母细胞瘤(Daoy)、人宫颈癌(HeLa)和人结肠癌(HT-29)。在测试的衍生物中,化合物4、10、16和19表现出良好的细胞毒活性。最活性的衍生物被评估为抑制血管内皮生长因子受体(VEGFR)-2的能力。化合物Z-4-(3-(3,4-二甲氧基苯基)-3-氧代丙-1-烯氨基)-N-(5-甲基-1,3,4-噻二唑-2-基)-苯磺酰胺10和Z-4-(3-(3,4-二甲氧基苯基)-3-氧代丙-1-烯氨基)-N-(1H-吲唑-6-基)-苯磺酰胺19作为VEGFR-2抑制剂的活性高于达沙替尼。最活性的衍生物在VEGFR-2活性部位的分子对接显示,化合物19呈现出有利的和有希望的结果。
