The abnormal biological functions of HDAC6 were closely related to the occurrence and development of various tumors, making HDAC6 gradually become promising therapeutic target for cancer treatment and inspiring researchers to explore and develop selective HDAC inhibitors. In this study, based on the classical pharmacophore model of HDAC inhibitors, 20 compounds were designed and synthesized by modifying
HDAC6的异常生物学功能与多种肿瘤的发生、发展密切相关,使得HDAC6逐渐成为癌症治疗的有希望的治疗靶点,并激励着研究人员探索和开发选择性HDAC抑制剂。本研究基于HDAC抑制剂的经典药效团模型,通过修饰Cap组设计合成了20个化合物,并通过抗增殖和酶抑制实验评估了目标化合物的生物学活性。标题化合物对选定的肿瘤细胞系表现出不同程度的抑制活性,尤其是化合物9m、9q和12c,在酶水平上进一步评估。酶抑制试验表明化合物12c具有广谱酶抑制活性,化合物9m和9q更倾向于抑制HDAC6,在代表性亚型中表现出一定的选择性抑制活性。此外,通过计算方法进一步探索了化合物9q和12c在HDAC1和6中的结合模式,以阐明选择性抑制活性的分子机制,为发现新型HDAC6抑制剂提供有价值的提示。
