  Class I HDAC Inhibitors Display Different Antitumor Mechanism in Leukemia and Prostatic Cancer Cells Depending on Their p53 Status

  摘要：

  Previously, we designed and synthesized a series of o-aminobenzamide-based histone deacetylase (HDAC) inhibitors, among which the representative compound 11a exhibited potent inhibitory activity against class I HDACs. In this study, we report the development of more potent hydrazide-based class I selective HDAC inhibitors using 11a as a lead. Representative compound 13b showed a mixed, slow, and tight binding inhibition mechanism for HDAC1, 2, and 3. The most potent compound 13e exhibited low nanomolar IC(50)s toward HDAC1, 2, and 3 and could down-regulate HDAC6 in acute myeloid leukemia MV4-11 cells. The EC50 of 13e against MV4-11 cells was 34.7 nM, which is 26 times lower than its parent compound 11a. In vitro responses to 13e vary significantly and interestingly based on cell type: in p53 wild-type MV4-11 cells, 13e induced cell death via apoptosis and G1/S cell cycle arrest, which is likely mediated by a p53-dependent pathway, while in p53-null PC-3 cells, 13e caused G2/M arrest and inhibited cell proliferation without inducing caspase-3-dependent apoptosis.

  摘要：

  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，

  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.

  greatly enhance potency of this class of inhibitors. Electronegative substitutions that favor a 90 degrees angle between the benzoyl ring and the amide bond yield the most potent compounds. There is a strong correlation between the potency of the compounds and the difference between the ab initio energy at 90 degrees and the global minima energy for given compounds. Combining the favored benzoyl substitutions
