well-reported, but moderate antitumor activity of the acronycine alkaloid led us to synthesize a novel series of thioacridone compounds related to acronycine, as potential anticancer agents. Compounds were designed either as DNA intercalating agents, or as DNA intercalating agents with covalent bond forming potential. Bathochromic shifts of the compounds upon complexation with salmon testis DNA suggested intercalation
丙烯醛生物碱的报道充分但中等的抗肿瘤活性使我们合成了一系列与丙烯醛有关的硫代rid啶酮化合物,作为潜在的抗癌药物。将化合物设计为DNA嵌入剂或具有共价键形成潜力的DNA嵌入剂。与鲑鱼睾丸DNA络合后,化合物的红移表明嵌入是DNA结合的方式。发现该化合物的结合相互作用约为10(2)M(-1),而最有效的化合物1-(2-二甲基氨基乙基氨基)-9(10H)-硫代rid啶的结合相互作用为10(4)M(- 1)。发现针对HL-60细胞的体外细胞毒性活性(IC50)为3.5至22μg/ mL。QSAR分析得出了一个多元线性回归方程,DNA结合的r2为0.847,r2为0。575为细胞毒性。QSAR分析中使用的物理化学参数是logP,极性表面积和计算出的摩尔折射率。还进行了对接研究,以比较研究中最有效和最不有效的化合物的结合,从而预测所需的化学特征,以在药物设计工作中进一步加以利用。该系列中的硫代rid
