title: Molecular docking of porphyrins with cationic limbs on intramolecular G-quadruplex.
abstract: We performed molecular docking simulations of porphyrins with cationic limbs on an intramolecular anti-parallel G-quadruplex and molecular dynamics simulations for the model complexes to explore plausible binding regions and modes. With grid-based scoring, GB/SA scoring and MM-PBSA method, two low-energy binding regions, a groove and a loop, for the porphyrins were identified.
