As a hot topic of epigenetic studies, histone deacetylases (HDACs) are related to lots of diseases, especially cancer. Further researches indicated that different HDAC isoforms played various roles in a wide range of tumor types. Herein a novel series of HDAC inhibitors with isatin-based caps and o-phenylenediamine-based zinc binding groups have been designed and synthesized through scaffold hopping
作为表观遗传学研究的热门话题,组蛋白脱乙酰基酶(HDAC)与许多疾病,尤其是癌症有关。进一步的研究表明,不同的HDAC亚型在多种肿瘤类型中起着不同的作用。在本文中,已经设计并通过支架跳跃策略合成了一系列具有基于靛红的帽和基于邻苯二胺的锌结合基团的HDAC抑制剂。在这些化合物中,与阳性对照恩替司他(MS-275)相比,最有效的化合物9n对多种肿瘤细胞系表现出相似的,甚至不是更好的HDAC抑制作用和抗增殖活性。此外,与MS-275(HDAC1、2和3的IC50值分别为0.163、0.396和0.605µM)相比,化合物9n的HDAC1、2和3的IC50值分别为0.032、0.256和0.311µM,
