Single nucleotide polymorphisms affecting galantamine binding to acetylcholinesterase in Alzheimer’s disease: a structural bioinformatics study

Abstract Galantamine, an acetylcholinesterase (AChE) inhibitor used for symptomatic treatment of Alzheimer’s disease (AD), shows substantial inter-individual variability in clinical response. Missense single nucleotide polymorphisms (SNPs) within the AChE active-site gorge may modulate inhibitor recognition. In this computational study, binding residues were defined from human AChE inhibitor co-crystal structures and cross-referenced with dbSNP missense variation, followed by in-silico predictio
