Identification of Selective α-Glucosidase Inhibitors via Virtual Screening with Machine Learning.

ABSTRACT: Given the limitations of clinical and potent natural α-glucosidase inhibitors, novel selective inhibitors are urgently needed. To accelerate discovery, we employed machine learning-integrated virtual screening to rapidly evaluate a library of 100 K⁺ compounds, identifying a series of selective α-glucosidase inhibitors. Activity validation demonstrated that these inhibitors exhibit significantly enhanced selectivity and potency compared to the positive control acarbose. Mechanistic studies through inhibition kinetics and fluorescence quenching revealed their improved inhibitory profile. Molecular docking indicates that key interactions-hydrogen bonding or salt bridges with the catalytic residue ASP526-strengthen binding within the active site. These interactions competitively obs
