Free ligand binding molecular dynamic simulations are a powerful tool used to probe the ligand binding process, mechanism and pathway and the insight gained can help expedite the early stages of drug discovery. Using these methods, we model the binding of two small molecule anti-cancer agents BRACO19 and CX-5461 to a variety of DNA G-quadruplexes (G4s) and a DNA Duplex. The first study focuses on the binding of BRACO19 to three different topological folds (parallel, anti-parallel and hybrid) of the human telomeric G4s. Our detailed analysis identified the most stable binding modes were end stacking and groove binding for the …
