Abstact

Glycogen synthase kinase-3β, also called tau phosphorylating kinase, is a proline-directed serine/threonine kinase which was originally identified due to its role in glycogen metabolism. Active forms of GSK3β localize to pretangle pathology including dystrophic neuritis and neurofibrillary tangles in Alzheimer's disease (AD) brain. By using a high throughput screening (HTS) approach to search for new chemical series and cocrystallization of key analogues to guide the optimization and synthesis of our pyrazine series, we have developed highly potent and selective inhibitors showing cellular efficacy and blood-brain barrier penetrance. The inhibitors are suitable for in vivo efficacy testing and may serve as a new treatment strategy for Alzheimer's disease.
