study, twenty three 3,6-disubstituted 1,2,4-triazolo[3,4-b]-1,3,4-thiadiazole derivatives were synthesized and their antiproliferative activities in vitro were studied against SMMC-7721, HeLa, A549, and L929 by the CCK-8 assay. The bioassay results demonstrated that all tested compounds 8(a–w) exhibited antiproliferation with different degrees, and some compounds showed better effects than reference drug
在这项研究中,合成了23个3,6-二取代的1,2,4-三唑并[3,4-b] -1,3,4-噻二唑衍生物,并研究了它们对SMMC-7721,HeLa的体外抗增殖活性,A549和L929通过CCK-8分析。生物测定结果表明,所有测试的化合物8(a – w)均表现出不同程度的抗增殖作用,并且某些化合物显示出比参考药物5-氟尿嘧啶更好的效果。在这些筛选出的化合物中,化合物8a,8d和8l在抑制SMMC-7721细胞增殖方面表现出显着的抗肿瘤活性,IC 50值分别为1.64、1.74和1.61 µM。化合物8d和8l与HeLa细胞相比,它们具有很高的生物学活性,其IC 50值分别为2.23和2.84 µM。发现化合物81具有对A549细胞的最高抗肿瘤效力,IC 50值为2.67μM。此外,在正常细胞系L929中,所有化合物均显示出比5-氟尿嘧啶弱的细胞毒性作用。
