, (2018/04/20)
Disclosed herein are 5 or 8-substituted imidazo [1, 5-a] pyridines and pharmaceutical compositions comprising at least one such 5 or 8-substituted imidazo [1, 5-a] pyridines, processes for the preparation thereof, and the use thereof in therapy. Disclosed herein are certain 5 or 8-substituted imidazo [1, 5-a] pyridines that can be useful for inhibiting indoleamine 2, 3-dioxygenase and/or tryptophane 2, 3-dioxygenase and for treating diseases or disorders mediated thereby.

Optimization of thienopyrimidinone derivatives as FGFR1 kinase inhibitors is being pursued. The present results confirm predictions of computational modeling that an aryl substituent can be introduced at the 2-position in structure 3. The substituent is anticipated to project deeper into the binding site and provide opportunities for enhanced activity and selectivity. The most potent analog reported herein, 13, has a 4-hydroxyphenyl substituent and yields an IC50 of 6 μM for inhibition of phosphorylation by FGFR1 kinase. It was also found that the western anisole-containing substituent in 3 can be replaced by a propionic acid group with no loss in potency and with potentially significant gains in pharmacologically relevant properties.
