minor groove and the intercalation of drugs into DNA may play critical roles in antiviral, antimicrobial, and antitumor activities. As a continuous effort to develop novel antiviral agents, the series of planar fluorenone (3a-7d) were synthesized and used along with nonplanar biphenyls (11a-d) for the comparative analysis of their interaction with DNA. The chemical structure of new compounds was confirmed
许多证据表明,小沟中的DNA药物相互作用以及药物嵌入DNA中可能在抗病毒,抗微生物和抗肿瘤活性中发挥关键作用。作为开发新型抗病毒剂的不懈努力,合成了一系列平面芴酮(3a-7d),并将其与非平面联苯(11a-d)一起用于比较它们与DNA的相互作用。通过1 H NMR,13 C NMR和质谱以及元素分析确认了新化合物的化学结构。通过溴化乙锭置换试验评价3a-7d和11a-d的DNA亲和力。发现3a-7d的亲和常数(lgKa)比相应的11a-d的常数高大约两个数量级。氨基烷氧基联苯(11a-d)分子对接至五个不同核苷酸序列(d(CCIICICCII),d(CGCGTTAACGCG),d(CGCGATATCGCG),d(GGCCAATTGG),d(GGATATATCC)的次要树丛中)显示了它们与特定的DNA位点。线性最小二乘拟合技术已成功应用于推导描述lgKa和SF之间关系的方程。
