Abstract [en]

Title compds. I [R1 = H or Me], and their pharmaceutically acceptable salts, are prepd. and disclosed as glycogen synthase kinase 3 (GSK3) inhibitors. Thus, e.g., II was prepd. by cyclization of 3-amino-N-(4-hydroxypyridin-3-yl)pyrazine-2-carboxamide (prepn. given) to get intermediate 3-(oxazolo[4,5-c]pyridin-2-yl)pyrazin-2-amine, which underwent bromination followed by Suzuki reaction with (4-methylpiperazin-1-yl)(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)methanone. Compds. of the invention were tested for their selective inhibitory activity of GSK3β, e.g., II exhibited Ki value of 2.3 nM. The invention compds. are useful for the treatment of cognitive disorders, diabetes, cancer, etc. [on SciFinder(R)]
