Discovery of highly potent TNFα inhibitors using virtual screen
چکیده انگلیسی


• Virtual screen targeting TNFα dimer was performed.
• Both SPR assay and cell-based study were used to confirm active compounds.
• Compound 11 was among the most potent TNFα small molecule inhibitors.
• All active compounds represent novel scaffolds as TNFα inhibitors.

Tumor necrosis factor-α (TNFα) is a validated therapeutic target for various autoimmune disorders such as rheumatoid arthritis and asthma. All TNFα inhibitors currently on the market are biologics, making the development of small molecule alternatives in urgent need. However, only a few successful cases of direct TNFα antagonization in vitro have been reported. Here, we present the identification of several small molecule candidates able to effectively reduce TNFα activity in vitro and in cell assays. Virtual screen targeting TNFα dimer was performed on the SPECS database and 101 compounds were selected for experimental testing. Two compounds, 1 and 2, displayed considerable inhibitory activity. Follow-up structure–activity relationship analysis of compound 1 identified 3 molecules with low micromolar cell-level inhibitory activity. Compound 11 showed an IC50 value of 14 μM, making it among the most potent TNFα small molecule inhibitors reported. These compounds provide new scaffolds for future development of small molecule drugs against TNFα.

We used virtual screen and discovered potent TNFα small molecule inhibitors with novel scaffolds. The best compound, 11, is among the strongest direct TNFα inhibitors reported to date.Figure optionsDownload as PowerPoint slide
