RESUMO
Cassava extracts containing cyanogenic compounds demonstrate anticancer properties. The cyanogenic glucoside linamarin found abundantly in cassava can release hydrogen cyanide (HCN) upon hydrolysis, a potent cytotoxin. However, linamarin's hydrolysis mechanism by human enzymes is poorly delineated and constitutes a bottleneck for therapeutic development. This study aimed to investigate linamarin's hydrolysis mechanism by human ß-glucosidase and identify structural derivatives with enhanced hydrolytic potential using density functional theory calculations. Results revealed α-anomeric derivatives as promising, with leaving group ability and steric bulk strongly governing hydrolysability. We identified several linamarin analogs with predicted rapid hydrolysis kinetics that may enable swift cytotoxic HCN release against cancer cells. This investigation enriches understanding of cyanogenic glycoside reactivity to facilitate their development as targeted antineoplastic agents. The identified derivatives set the groundwork for experimental evaluation of enhanced linamarin-inspired compounds as innovative cancer therapeutics.
