Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest cancers due to its late diagnosis, resistance therapy, and a dismal 5-year survival rate only 12%. Overexpression PKMYT1—a key regulator cell cycle—correlates with poor patient outcomes, making it promising therapeutic target. In this study, we identify CMNPD31124, novel marine-derived indole alkaloid, as potent PKMYT1 inhibitor. Molecular docking revealed that CMNPD31124 has superior binding affinity compared reference compound Cpd 4, forming robust interactions critical residues such CYS-190, TYR-121, GLY-122. dynamics simulations further demonstrated stable conformation dynamic adaptability, Chai-1 modeling supporting covalent mechanism at active site. Importantly, in vitro assays showed exhibits an IC 50 18.6 μM MiaPaCa-2 cells 31.7 BXPC3 cells, while concentrations up 80 did not significantly affect normal pancreatic cells. Despite these results, toxicity predictions indicate potential hepatotoxicity neurotoxicity, highlighting need for structural optimization. This work lays solid foundation rational design inhibitors by integrating computational methods insights from marine natural products.
