Lenvatinib (LEN), sorafenib (SOR), and sunitinib (SUN) are drugs targeting vascular endothelial growth factor receptor 2 (VEGFR2). Despite sharing similar chemical structures and bioactivities, LEN and SOR bind to different functional states of VEGFR2, viz. DFG-in and DFG-out state, respectively. SUN binds to the DFG-out state of VEGFR2 just like SOR but with less potency. Thus, detail binding mechanisms between VEGFR2 and these drugs, especially dynamic interaction, are valuable for future drug design. In the present work, molecular dynamics simulation, essential dynamic analysis, and molecul...
