hydroxamic acid histone deacetylase (HDAC) inhibitors in which the β-carboline motif has been incorporated were designed and synthesized. The effect of substitution at the C3 amide on HDAC inhibition and antiproliferative activities was investigated. Most of these compounds were found to display significant HDAC inhibitory effects and good antiproliferative activity, with IC50 values in the low-micromolar
设计并合成了一系列掺入了β-咔啉基的异羟肟酸组蛋白脱乙酰基酶(HDAC)抑制剂。研究了在C3酰胺处的取代对HDAC抑制和抗增殖活性的影响。发现这些化合物大多数显示出显着的HDAC抑制作用和良好的抗增殖活性,IC50值在低微摩尔范围内。特别是,N-(2-(二甲基氨基)乙基)-N-(4-(羟基氨基甲酰基)苄基)-1-(4-甲氧基苯基)-9H-吡啶并[3,4-b]吲哚的HDAC抑制IC50值-3-羧酰胺(9小时)比辛二酰苯胺异羟肟酸(SAHA,伏立诺他)低五倍。此外,发现9小时可增加组蛋白H3和α-微管蛋白的乙酰化,并通过变色现象和组蛋白H2AX磷酸化增强证明DNA损伤。化合物9h抑制Stat3,Akt和ERK信号转导,这是重要的细胞生长促进途径,在大多数癌症中均被异常激活。最后,9 h在Caco-2细胞中显示出合理的溶解度和通透性。我们的发现表明,这些新型的基于β-咔啉的HDAC抑制剂作为治疗人类癌症的治疗剂可能具有广阔的前景。
