Structural basis for the GSK-3beta binding affinity and selectivity against CDK-2 of 1-(4-aminofurazan-3yl)-5-dialkylaminomethyl-1H-[1,2,3] triazole-4-carboxylic acid derivatives.
A novel structural class of glycogen synthase kinase-3beta inhibitors is modeled using quantum mechanics, automated docking, and molecular dynamics simulations. The proposed binding modes identify important hydrogen bonds and salt-bridges with the ATP-binding pocket of the kinase. The modeled complexes justify the observed structure-activity relationships and provide a structural basis for the high selectivity of these inhibitors against cyclin dependent kinase-2.
