, (2008/06/13)
New pyrimidine or pyridine based compounds, compositions and methods of inhibiting the activity of glycogen synthase kinase (GSK3) in vitro and of treatment of GSK3 mediated disorders in vivo are provided. The methods, compounds and compositions of the invention may be employed alone, or in combination with other pharmacologically active agents in the treatment of disorders mediated by GSK3 activity, such as diabetes, Alzheimer's disease and other neurodegenerative disorders, obesity, atherosclerotic cardiovascular disease, essential hypertension, polycystic ovary syndrome, syndrome X, ischemia, traumatic brain injury, bipolar disorder, immunodeficiency or cancer.

Reaction of substituted 2-aminopyridines IIIa, IIIb, IIIe, and IIIf with ethyl ethoxymethylene malonate provided corresponding pyridylaminomethylenemalonates Va-Vd, respectively.Thermal cyclization of Va, Vc, and Vd yielded substituted ethyl 4-hydroxy-1,7-naphthyridine-3-carboxylates VIa, VIc, and VId.Compounds VIc and VId treated with morpholine have 8-morpholino derivatives VIe and VIf.These compounds were ethylated to mixtures of N-ethylated (VIIa, VIIb) and O-ethylated products (VIIIa, VIIIb).Compound VIIIb was also prepared from ethyl 4-chloro-6-fluoro-8-morpholino-1,7-naphthyridine-3-carboxylate VIIIc and sodium ethanolate.Esters VIIa and VIIb were hydrolyzed under acidic conditions to the respective acids VIIc and VIId.
