Modeling binding modes of alpha7 nicotinic acetylcholine receptor with ligands: the roles of Gln117 and other residues of the receptor in agonist binding.

Abstract excerpt

Extensive molecular docking, molecular dynamics simulations, and binding free energy calculations have been performed to understand how alpha7-specific agonists of nicotinic acetylcholine receptor (nAChR), including AR-R17779 (1), GTS-21 (4), and 4-OH-GTS-21 (5), interact with the alpha7 receptor, leading to important new insights into the receptor-agonist binding. In particular, the cationic head of 4 and 5 has...
