(AD). Its inhibition is a valid approach to the treatment of AD. In this initial letter, some thienyl and phenyl alpha-halomethyl ketones are described as new non-ATP competitive inhibitors of GSK-3beta. They are considered as lead compounds for designing and synthesizing new series, to carry out SAR studies, clear up the mechanism of action, and, in general, evaluate their therapeutical usefulness.
electron-donating substituents at the 3-position of the thiophene rings was synthesized, and the effects of the substituents on the structure, stability, and π-dimerization ability of the radical cation were investigated using UV–vis–NIR and electron spin resonance spectra and density functional theory (DFT) calculations. Among the electron-donating methyl, methoxy, and methylthio substituents, the methoxy derivative

Thienylhalomethylketones, whose chemical, biological, and pharmaceutical data are here reported, are the first irreversible inhibitors of GSK-3 beta described to date. Their inhibitory activity is likely related to the cysteine residue present in the ATP-binding site, which is proposed as a relevant residue for modulation of GSK-3 activity. The good cell permeability of the compounds allows them to be used in different cell models. Overall, the results presented here support the potential use of halomethylketones as pharmacological tools for the study of GSK-3 beta functions and suggest a new mechanism for GSK-3 beta inhibition that may be considered for further drug design.
