assay against the full panel NCI-cancer cell lines. 3d displayed higher antitumor activity against most tested cancer cell lines than 5-FU as reference. COMPARE analysis and molecular electrostatic potential computational study revealed that 3d probably exerts its antitumor properties through DNA binding similar to Clomesone. Further DNA binding studies using fluorescent terbium (Tb+3) probe revealed
新系列的呋喃-噻唑杂种(3a-f),噻唑[2,3-c] -1,2,4-三嗪(4a-f),它们的生物等排体1,3,4-噻二唑[2,3-c设计,合成并评估了] -1,2,4-三嗪(8a-d)和1,2,4-三嗪[4,3-b] -1,2,4-三嗪(13a-e)美国国家癌症研究所(NCI)的体外抗肿瘤活性。在合成的化合物中,发现3d在针对全组NCI癌细胞系的五剂量试验中显示出有希望的广谱抗肿瘤活性(GI50 MG-MID = 14.22 µM)。3d显示出对大多数测试癌细胞系的抗肿瘤活性高于5-FU作为参考。COMPARE分析和分子静电潜能计算研究表明3d可能通过与Clomesone相似的DNA结合发挥其抗肿瘤特性。使用荧光ter(Tb + 3)探针进行的进一步DNA结合研究表明,由于双链DNA的损伤,DNA-3d-Tb + 3混合物的荧光强度增加。另外,进行了UV-vis吸收研究,该研究表明DNA
