Molecular docking simulations Molecular docking analysis was implemented using the Surflex-Dock module in Sybyl-X2.2.1 (Tripos Inc, St Louis, MO, USA) with the known crystal structure of AXL complexed with ligands (PDB ID: 5U6B). To prepare the protein, hydrogen was added and energy was minimized using Powell’s method with the Tripos push field until the root-mean-square derivation (RMSD) ideals were 0.05 Kcal/mol?. Initial optimization and termination of minimization were arranged as simplex and gradient, respectively. The new ligands were prepared using Chem3D (PerkinElmer, Waltham, MA, USA). Molecular docking simulations were carried out using the Surflex-Dock setting with the removal of the initial ligand. To create the energetic site, a threshold of 0.5 ? and bloat of 0 ? had been applied predicated on the initial ligand in the crystal framework. Other parameters had been utilized as default. The outcomes from the docking simulation had been validated by evaluating the redocked framework to the initial pose from the ligand. Molecular interactions between proteins and ligands were analyzed using Discovery Studio room 4 additional.0 Visualizer (BIOVIA, NORTH PARK, CA, USA).
