A series of benzamide-based histone deacetylases (HDACs) inhibitors possessing N-(aminopyridine) residue as the zinc binding site of HDAC were synthesized and evaluated. Among these derivatives, compounds with N-(2-amino-4-pyridine) benzamide moiety have been found as the most potent ones. Moreover, introduction of appropriate substituents on the terminal aryl group acting as the surface-recognition domain could significantly improve the antiproliferative activity. In particular, the compound 4k possessed favorable pharmacokinetic characteristics and exhibited potent antitumor activity on xenograft model in mice at well tolerated doses, thus suggesting a good therapeutic index.
研究人员合成并评估了一系列苯甲酰胺类组蛋白去乙酰化酶(HDACs)抑制剂,这些抑制剂以 N-(氨基吡啶)残基作为 HDAC 的锌结合位点。在这些衍生物中,发现具有 N-(2-氨基-4-吡啶)苯甲酰胺分子的化合物是最有效的。此外,在作为表面识别域的末端芳基上引入适当的取代基,可以显著提高抗增殖活性。特别是,化合物 4k 具有良好的药代动力学特征,并在小鼠异种移植模型上以良好的耐受剂量表现出强效抗肿瘤活性,从而表明其具有良好的治疗指数。
