We report in this study the identification of a natural product-like antagonist () of Vps34 as a potent autophagy modulator structure-based virtual screening. Aurone derivative strongly inhibited Vps34 activity in cell-free and cell-based assays. Significantly, prevents autophagy in human cells induced either by starvation or by an mTOR inhibitor. modeling and kinetic data revealed that could function as an ATP-competitive inhibitor of Vps34. Moreover, it suppressed autophagy and without inducing heart or liver damage in mice. could be utilized as a new motif for more selective and efficacious antagonists of Vps34 for the potential treatment of autophagy-related human diseases.
在本研究中,我们报告了通过基于结构的虚拟筛选鉴定出一种类天然产物的Vps34拮抗剂()作为一种有效的自噬调节剂。在无细胞和基于细胞的实验中,橙酮衍生物强烈抑制Vps34活性。重要的是,可防止饥饿或mTOR抑制剂诱导的人细胞自噬。建模和动力学数据表明,可作为Vps34的ATP竞争性抑制剂发挥作用。此外,它在小鼠中抑制自噬且不诱导心脏或肝脏损伤。可作为Vps34更具选择性和有效性的拮抗剂的新基序,用于潜在治疗自噬相关的人类疾病。
