Multitarget inhibitors design has generated great interest in cancer treatment. Based on the synergistic effects of topoisomerase and histone deacetylase inhibitors, we designed and synthesized a new series of acridine hydroxamic acid derivatives as potential novel dual Topo and HDAC inhibitors. MTT assays indicated that all the hybrid compounds displayed good antiproliferative activities with IC50
多靶点抑制剂的设计引起了人们对癌症治疗的极大兴趣。基于拓扑异构酶和组蛋白脱乙酰基酶抑制剂的协同作用,我们设计和合成了一系列新的of啶异羟肟酸衍生物,它们是潜在的新型双重Topo和HDAC抑制剂。MTT分析表明,所有杂合化合物均显示出良好的抗增殖活性,其IC 50值在低微摩尔范围内,其中化合物8c显示出对U937的有效活性(IC 50 = 0.90μM)。另外,化合物8c还显示出最佳的HDAC抑制活性,其效力是HDAC抑制剂SAHA的几倍。随后的研究表明,所有化合物在50μM下均表现出Topo II抑制活性。此外,化合物8c可以与DNA相互作用并诱导U937细胞凋亡。这项研究提供了一套化合物,可用于进一步探索双重Topo和HDAC抑制剂,并且化合物8c可以是新型的双重Topo和HDAC抑制性抗癌药。
