Popis: Nur77 modulators have emerged as a promising therapeutic approach for hepatocellular carcinoma. In this study, a structure-based rational drug design approach was used to design and synthesise a series of 4-((8-hydroxy-2-methylquinolin-4-yl)amino)benzoylhydrazone derivatives based on the binding characteristics of our previously reported 10g and the native ligand 3NB at the binding Site C of Nur77. Cell-based cytotoxicity assays revealed that compound TMHA37 demonstrated the highest cytotoxicity against all tested cancer cells. The induced fit docking and binding pose metadynamics simulation suggested that TMHA37 was the most promising Nur77 binder at Site C. Molecular dynamics simulation validated the stable binding of TMHA37 to Nur77’s Site C but not to Sites A or B. Specifically, TMHA37 bound strongly to Nur77-LBD (KD = 445.3 nM) and could activate Nur77’s transcriptional activity. Furthermore, TMHA37 exhibited antitumor effects by blocking the cell cycle at G2/M phase and inducing cell apoptosis in a Nur77-dependent manner.
