PubMed Abstract: Glycogen synthase kinase-3 (GSK-3) is a serine/threonine kinase that regulates numerous cellular processes, including metabolism, proliferation, and cell survival. Due to its multifaceted role, GSK-3 has been implicated in a variety of diseases, including Alzheimer's disease, type 2 diabetes, cancer, and mood disorders. GSK-3β has been linked to the formation of the neurofibrillary tangles associated with Alzheimer's disease that arise from the hyperphosphorylation of tau protein. The design and synthesis of a series of imidazo[1,2-]pyridazine derivatives that were evaluated as GSK-3β inhibitors are described herein. Structure-activity relationship studies led to the identification of potent GSK-3β inhibitors. In vivo studies with in a triple-transgenic mouse Alzheimer's disease model showed that this compound is a brain-penetrant, orally bioavailable GSK-3β inhibitor that significantly lowered levels of phosphorylated tau.
