PubMed Abstract:
The discovery of a novel series of 2-(4-pyridyl)thienopyridinone GSK-3β inhibitors is reported. X-ray crystallography reveals its binding mode and enables rationalization of the SAR. The initial optimization of the template for improved cellular activity and predicted CNS penetration is also presented.
