acridine derivatives were synthesized as an extension of our discovery of acridine antitumor agents. Most of these acridine compounds displayed good antiproliferative activity with IC50 values in low micromole range and structure-activity relationships were studied. Topo I- and II- mediated relaxation studies suggested that all of our compounds displayed strong Topo II inhibitory activity at 100 μM
合成了一系列9-苄基氨基a啶衍生物,作为我们对discovery啶抗肿瘤剂的发现的扩展。这些a啶化合物中的大多数显示出良好的抗增殖活性,并且在低微摩尔范围内具有IC 50值,并研究了结构-活性关系。Topo I和II介导的弛豫研究表明,我们所有的化合物在100μM时均显示出强大的Topo II抑制活性,而只有四个化合物表现出中等的Topo I抑制活性。典型的化合物8p可以有效地穿透A549癌细胞。化合物8p可以插入双链DNA结构内并引起DNA损伤。此外,化合物8p 可以通过胱天蛋白酶依赖性内在途径诱导A549细胞凋亡,并使A549细胞停滞在G2 / M期。
