pulmonary fibrosis is incurable, and its progression is difficult to control and thus can lead to pulmonary deterioration. Pan-histone deacetylase inhibitors such as SAHA have shown potential for modulating pulmonary fibrosis yet with off-target effects. Therefore, selective HDAC inhibitors would be beneficial for reducing side effects. Toward this goal, we designed and synthesized 24 novel HDAC6, HDAC8
特发性肺纤维化无法治愈,其进展难以控制,因此可导致肺部恶化。泛组蛋白脱乙酰酶抑制剂(例如 SAHA)已显示出调节肺纤维化的潜力,但具有脱靶效应。因此,选择性HDAC抑制剂将有利于减少副作用。为了实现这一目标,我们设计并合成了24种新型HDAC6、HDAC8或双HDAC6/8抑制剂,并建立了两阶段筛选平台来快速筛选有效减轻TGF-β诱导的肺纤维化的HDAC抑制剂。第一阶段包括小鼠 NIH-3T3 成纤维细胞预筛选,并产生了 5 次命中。在第二阶段,使用人肺成纤维细胞 (HPF),并对 5 个命中中的 4 个进行了 caco-2 渗透性和肝微粒体稳定性测试,以给出两个潜在的线索:J27644 (15 )和20。这种新颖的两阶段筛选平台将加速 HDAC 抑制剂的发现并降低开发成本,以减轻 TGF-β 诱导的肺纤维化。
