Previously, we reported the discovery of a series of N-hydroxycinnamamide-based HDAC inhibitors, among which compound 11y exhibited high HDAC1/3 selectivity. In this current study, structural derivatization of 11y led to a new series of benzamide based HDAC inhibitors. Most of the compounds exhibited high HDACs inhibitory potency. Compound 11a (with 4-methoxybenzoyl as N-substituent in the cap and
以前,我们报道了一系列基于N-羟基肉桂酰胺的HDAC抑制剂的发现,其中化合物11y具有高HDAC1 / 3选择性。在本研究中,11y的结构衍生化导致了一系列新的基于苯甲酰胺的HDAC抑制剂。大多数化合物显示出高的HDAC抑制能力。化合物11a(在帽中具有4-甲氧基苯甲酰基作为N-取代基,而4-(氨基甲基)苯甲酰基作为连接基团)在一定程度上显示出对HDAC1的选择性,并且显示出对几种肿瘤细胞系的有效抗增殖活性。体内研究表明,化合物11a在血液肿瘤细胞U937异种移植模型和实体肿瘤细胞HCT116异种移植模型中均显示出有效的口服抗肿瘤活性,且无明显毒性。进一步改性苯甲酰胺3,
