In this study, 12 novel 2-((1-(4-(1H-imidazol-1-yl)phenyl)ethylidene)hydrazineylidene)-3-ethyl-4-(substitutephenyl)-2,3-dihydrothiazole derivatives were obtained. Among these compounds, 2-((1-(4-(1H-imidazol-1-yl)phenyl)ethylidene)hydrazineylidene)-4-([1,1′-biphenyl]-4-yl)-3-ethyl-2,3-dihydrothiazole (4h) was chosen as the most active derivative in the series. According to the MTT results, compounds
本研究获得了12种新型2-((1-(4-(1 H-咪唑-1-基)苯基)亚乙基)亚肼基)-3-乙基-4-(取代苯基)-2,3-二氢噻唑衍生物。这些化合物中,2-((1-(4-(1H-咪唑-1-基)苯基)亚乙基)亚肼基)-4-([1,1'-联苯基]-4-基)-3-乙基-2,3-二氢噻唑(4h)被选为该系列中最活跃的衍生物。MTT结果显示,化合物4h和4k显示出活性,IC 50分别为4.566±0.246 μM和IC 50 =4.537±0.463 μM。与其他衍生物不同,化合物4h在苯环的第4位带有苯环。这个庞大的基团使化合物能够沉淀在酶活性位点。动态研究表明,该化合物的稳定性在 40 ns 内不会发生变化。RMSD、RMSF 和 Rg 参数均保持在可接受的范围内。酶活性位点与重要氨基酸Cys919、Glu885和Asp1046的不间断芳香氢键结合证明了化合物4h对VEGFR-2酶的抑制潜
