As an extension for our earlier effort in the field of discovery of anticancer agents acting on DNA and Topo II, eighteen quinoxaline derivatives were designed and synthesized. Such members were designed to possess the main essential pharmacophoric features of DNA intercalators. The cytotoxic potential of the synthesized compounds was assessed against a group of human cancer cell lines (HCT-116, HepG2
作为我们在发现作用于DNA和Topo II的抗癌药领域的早期工作的扩展,设计和合成了18种喹喔啉衍生物。设计此类成员具有DNA嵌入剂的主要基本药效学特征。针对一组人类癌细胞系(HCT-116,HepG2和MCF-7)评估了合成化合物的细胞毒性潜力。阿霉素作为潜在的插入式Topo II抑制剂,被用作阳性参考。一般情况下,化合物12,15,19,21,和22显示出有希望的抗增殖活性针对与IC三种细胞系50值范围从2.81到10.23 µM。评估了活性最高的化合物对正常人细胞(WI-38)的细胞毒性,结果表明这些化合物具有较低的毒性。还对作为Topo II抑制剂的最具活性的抗增殖成员进行了进一步检查,发现抑制活性范围很窄(0.45至1.06 µM)。另外,进行了DNA /甲基绿测定以评估此类化合物的DNA结合潜力。结果表明这些化合物具有强至中等的DNA结合亲和力,范围为33.48至51.23 µ
