Traditional screening has struggled to identify selective EGFR-T790M inhibitors. A Bayesian-inference integrated machine learning workflow screened 70,413 compounds and selected candidates with preferential EGFR-T790M binding. In vitro assays, molecular dynamics, cellular thermal shift, and xenograft validation confirmed CDDO-Me as a selective suppressor of NSCLC growth via apoptosis, cell-cycle arrest, and PI3K-Akt-mTOR inhibition.","Zhou et al.

Identification of new selective EGFR-T790M inhibitors has proven challenging through traditional screening platforms. With great advances in computer algorithms, machine learning improved the screening rates of molecules at full chemical spaces, and these molecules will present higher biological activity and targeting efficiency.  \nMethods An integrated machine learning approach, integrated by Bayesian inference, was employed to screen a commercial dataset of 70,413 molecules, identifying candidates that selectively and efficiently bind with EGFR harboring T790M mutation. In vitro cellular assays and molecular dynamic simulations was used for validation. EGFR knockout cell line was generated for cross-validation. In vivo xenograft moues model was constructed to investigate the antitumor efficacy of CDDO-Me.  \nResults Our virtual screening and subsequent in vitro testing successfully identified CDDO-Me, an oleanol ic acid derivative with anti-inflammatory activity, as a potent inhibitor of NSCLC cancer cells harboring the EGFR-T790M mutation. Cellular thermal shift assay and molecular dynamic simulation validated the selective binding of CDDO-MetoT790M-mutant EGFR. Further experimental results revealed that CDDO-Me induced cellular apoptosis and caused cell cycle arrest through inhibiting the PI3K-Akt-mTOR axis by directly targeting EGFR protein, cross-validated by sgEGFR silencing in H1975 cells. Additionally, CDDO-Me could dose-depended suppress the tumor growth in a H1975 xenograft mouse model.  \n\n| †Rui Zhou, Ziqian Liu and Tongtong Wu contributed equally to this work. |\n| --- |\n| †Haigang Wu and Ning Liu are joint senior author. |\n\n*Correspondence: Beier Jiang [674358923@qq.com](674358923@qq.com)[ ](674358923@qq.com)Zhenzhen Zhang [zz_jane@163.com](zz_jane@163.com)[ ](zz_jane@163.com)Ning Liu[nliu@shou.edu.cn](nliu@shou.edu.cn)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2024.
