vacuolin-1 analogues as autophagy inhibitors. Based on these virtual screening results, we further designed and synthesized 17 vacuolin-1 analogues, and found that 13 of them are autophagy inhibitors and a couple of them are as potent as vacuolin-1. In summary, these studies expanded the pool of useful autophagy inhibitors and reveal the structural-activity relationship of vacuolin-1 analogues, which is
自噬是一种基本的细胞降解过程,对细胞稳态至关重要,功能失调的自噬与多种人类疾病(如癌症)有关。几种自噬化学调节剂已应用于许多针对这些自噬相关疾病,尤其是癌症的临床前或临床试验。小分子 vacuolin-1 有效且可逆地抑制内体-溶酶体运输和自噬体-溶酶体融合,但 vacuolin-1 介导的自噬抑制的分子机制仍然未知。在这里,我们首先进行了虚拟药物筛选,并确定了 14 种 vacuolin-1 类似物作为自噬抑制剂。基于这些虚拟筛选结果,我们进一步设计合成了 17 个 vacuolin-1 类似物,并发现其中 13 种是自噬抑制剂,其中一些与 vacuolin-1 一样有效。总之,这些研究扩展了有用的自噬抑制剂库,并揭示了 vacuolin-1 类似物的结构-活性关系,这对于未来开发具有高效力的 vacuolin-1 类似物和鉴定 vacuolin-1 的分子靶标很有用.
