“…Cloud and distributed computing resources also provide this type of completely parallel solution for high-throughput screening 35,36 . The use of GPUs has recently been made possible for the widely-used program AutoDock4 37,38 resulting in the program AutoDock-GPU, which provides up to 50X speedup over AutoDock4 (available at https://github.com/ccsb-scripts/AutoDock-GPU) [39][40][41] . Thus, the use of leadership HPC facilities for ensemble docking can provide the ability to screen billions of ligands to a full set of conformations generated with HPC-based MD simulations.…”

“…AMBER UNITED force field electrostatic charges [ 53 ] were loaded on the protein structure, while the molcharge complement of QUACPAC [ 54 ] was used in order to achieve Marsili-Gasteiger charges for the inhibitors. Affinity maps were calculated firstly on a 0.500 Å spaced 100 × 100 × 100 Å 3 cubic box in the blind test dockings, and afterwards on 0.375 Å spaced 85 × 85 × 85 Å 3 cubic box, centered on thedonepezil crystallized structures, and the accessibility of the binding site was exploited throughout 1000 runs of Lamarckian Genetic Algorithm (LGA) implemented in AUTODOCK 4.2.6 [ 55 ] using the GPU-OpenCL algorithm version [ 56 ]. Explicit water contribution was taken into account according to the hydration force field of AUTODOCK [ 57 ], and the population size and the number of energy evaluations figures were set to 300 and 10000000, respectively.…”

“…Due to the presence of FAD in the enzyme molecular assembly, Marsili‐Gasteiger charges were applied to both the protein and ligands to normalize the electrostatic potentials in the free energy evaluation. Binding mode of each derivative was sampled with a thousand runs of Lamarckian Genetic Algorithm (LGA) implemented in AUTODOCK 4.2.6 using the GPU‐OpenCL algorithm version . To accomplish this task, affinity maps were first calculated on a 70×70×70 Å 3 box, 0.375 Å spaced, centered on the co‐crystallized coumarin, and LGA runs were issued with population size and the number of energy evaluations to 300 and 10 000 000 respectively, considering water contribution according to the hydration force field of AUTODOCK .…”

“…Binding mode of each derivative was sampled with a thousand runs of Lamarckian Genetic Algorithm (LGA) implemented in AUTODOCK 4.2.6 [29] using the GPU-OpenCL algorithm version. [30] To accomplish this task, affinity maps were first calculated on a 70 × 70 × 70 Å 3 box, 0.375 Å spaced, centered on the co-crystallized coumarin, and LGA runs were issued with population size and the number of energy evaluations to 300 and 10 000 000 respectively, considering water contribution according to the hydration force field of AUTODOCK. [31] All the docked poses were thereafter clustered, and the best free energy/most populated pose selected as representative of the binding mode.…”
