deacetylase inhibitors (HDACi) have emerged as promising therapeutics for the treatment of neurodegeneration, cancer, and rare disorders. Herein, we report the development of a series of spiroindoline-based HDAC6 isoform-selective inhibitors based on the X-ray crystal studies of the hit 6a. We identified compound 6j as the most potent and selective hHDAC6 inhibitor of the series. Biological investigation
组蛋白去乙酰化酶抑制剂 (HDACi) 已成为治疗神经退行性疾病、癌症和罕见疾病的有前途的疗法。在此,我们报告了基于命中6a的 X 射线晶体研究的一系列基于螺二氢吲哚的 HDAC6 异构体选择性抑制剂的开发。我们确定化合物6j是该系列中最有效和最具选择性的h HDAC6 抑制剂。化合物6b、6h、6j的生物学研究证明了它们对几种癌细胞系的抗增殖活性。蛋白质印迹研究表明,它们能够增加微管蛋白乙酰化,而组蛋白乙酰化状态没有显着变化,并诱导 PARP 裂解,表明它们在分子水平上具有凋亡潜力。6j诱导 HDAC6 依赖性 pSTAT3 抑制。
