and A549 lines. Bioassay indicated that some compounds showed stronger antitumor effects than reference drugs PX-12 and 5-fluorouracil. Among these screened compounds, compound 7h showed excellent biological activities in inhibiting SMMC-7721 cell proliferation with IC50 at 1.93 ± 0.08 μM. Compounds 7k and 7i manifested highly effective growth inhibitory activity versus MCF-7 cells, with IC50 at 3.04 ± 0
在本研究中,制备了十四个含二硫基的2,5-二取代的1,3,4-噻二唑衍生物。通过IR,NMR,MS和元素分析鉴定了所得化合物7a – 7n。使用针对SMMC-7721,MCF-7和A549品系的标准CCK-8分析法研究了它们的体外抗增殖特性。生物测定表明,某些化合物显示出比参考药物PX-12和5-氟尿嘧啶更强的抗肿瘤作用。在这些筛选出的化合物中,化合物7h以1.93±0.08μM的IC 50抑制SMMC-7721细胞增殖具有优异的生物学活性。化合物7k和7i与MCF-7细胞相比,具有明显的高效生长抑制活性,IC 50分别为3.04±0.09和3.54±0.17μM。对于A549细胞,发现化合物7m具有最高的抗肿瘤效力,IC 50为3.67±0.13μM。
