Discovery of 1,8-acridinedione derivatives as novel GCN5 inhibitors via high throughput screening
摘要:
The general control nonrepressed protein 5 (GCN5) plays a crucial role in many biological processes. Dysregulation of GCN5 has been closely related to various human diseases, especially cancers. Hence, the exploitation of small molecules targeting GCN5 is essential for drug design and academic research. Based on the amplified luminescent proximity homogeneous assay screen methodology, we performed high throughput screening and discovered a novel GCN5 inhibitor DC_G16 with 1,8-acridinedione scaffold. Structure optimization led to the identification of a highly potent inhibitor, namely DC_G16-11 with the half-maximal inhibitory concentration (IC50) value of 6.8 mu M. The binding between DC_G16-11 and GCN5 was demonstrated by NMR and SPR with a K-D of 4.2 mu M. It could also inhibit proliferation and induce cell cycle arrest and apoptosis in cancer cells while it presented minimal effects on normal cells. Herein, DC_G16-11 could be applied as a validated chemical probe for GCN5-related biological function research and presented great potential for clinical disease treatment.
