compound 8 with DNA have been investigated with absorption, emission and circular dichroism as well as thermal denaturation experiments which indicate intercalation with base pairs of human and calf thymus DNA. The molecular docking and site-selective binding studies also reveal the predominant intercalation of compound 8 in base pairs of DNA. The interaction between thiazolidine based phenanthrene 8 and
合成了一系列在C2-位具有不同芳基的菲[9,10- d ]咪唑/恶唑和ena [1,2- d ]咪唑。这些化合物在体外评估了针对一组60种人类癌细胞系的抗肿瘤活性。化合物8对白血病,结肠癌,黑色素瘤,肾癌和乳腺癌细胞系的细胞毒性高于其他评估的细胞组,并且对正常细胞系Hek293的毒性低。化合物8的结合性能已经通过吸收,发射和圆二色性以及热变性实验研究了DNA与DNA的结合,该实验表明与人和小牛胸腺DNA的碱基对插入。分子对接和位点选择性结合研究还揭示了化合物8在DNA碱基对中的主要嵌入。还研究了基于噻唑烷的菲8与转运蛋白的血清白蛋白(HSA和BSA)之间的相互作用,该相互作用通过静态机制显示出荧光的猝灭。从范霍夫(Van't Hoff)关系获得的热力学参数表明了氢键/疏水相互作用对于结合现象的普遍性。
