ABSTRACT
The glycogen synthase kinase-3 (GSK-3) has been linked to the pathogenesis of colorectal cancer, diabetes, cardiovascular disease, acute myeloid leukemia (AML), and Alzheimer's disease (AD). The debate on the respective contributions of GSK-3α and GSK-3ß to AD pathology and AML is ongoing. Thus, the identification of potent GSK-3α-selective inhibitors, endowed with favorable pharmacokinetic properties, may elucidate the effect of GSK-3α inhibition in AD and AML models. The analysis of all available crystallized GSK-3 structures provided a simplified scheme of the relevant hot spots responsible for ligand binding and potency. This resulted in the identification of novel scorpion shaped GSK-3 inhibitors. It is noteworthy, compounds 14d and 15b showed the highest GSK-3α selectivity reported so far. In addition, compound 14d did not display significant inhibition of 48 out of 50 kinases in the test panel. The GSK-3 inhibitors were further profiled for efficacy and toxicity in the wild-type (wt) zebrafish embryo assay.
