- W2912742968 abstract "Acetylcholinesterase (AChE) is an important kind of esterase that plays a key biological role in the central and peripheral nervous systems. Recent research has demonstrated that some fullerene derivatives serve as a new nanoscale class of potent inhibitors of AChE, but the specific inhibition mechanism remains unclear. In the present article, several molecular modeling methods, such as molecular docking, molecular dynamics simulations and molecular mechanics/generalized Born surface area calculations, were used for the investigation of the binding mode and inhibition mechanism of fullerene inhibitions for AChE. Results revealed that fullerene inhibitors block the entrance of substrates by binding with the peripheral anionic site (PAS) region. Thus, fullerene derivatives might mainly serve as competitive inhibitors. The interactions of a fullerene backbone with AChE are at the same level in different single side chain systems and seem to be related to the length or aromaticity of the side chain. The inhibitor with multihydroxyl side chains shows an obviously large electrostatic interaction as it forms additional hydrogen bonds with AChE. Moreover, fullerene derivatives might exhibit noncompetitive inhibition partly by affecting some secondary structures around them. Thus, the destructions of these secondary structures can lead to conformational changes in some important regions, such as the catalytic triad and acyl pocket. The investigation is of great importance to the discovery of good fullerene inhibitors.Communicated by Ramaswamy H. Sarma" @default.
