General description

A cell-permeable imidazopyrimidine compound that acts a potent, ATP-competitive, reversible, and highly selective inhibitor of Syk tyrosine kinase activity (IC50 = 10 nM) with no inhibitory effect against Btk, Fyn, Itk, Lyn, and Src even at concentrations as high as 4.7 µM. Shown to inhibit Syk-mediated cellular functions in vitro and exhibit good oral bioavailability and in vivo effacacy in the treatment of various allgery and asthma conditions in rat models.

Mycobacterial cell-wall glycolipids elicit an anti-mycobacterial immune response via FcRγ-associated C-type lectin receptors, including Mincle, and caspase-recruitment domain family member 9 (CARD9). Additionally, mycobacteria harbor immuno-evasive cell-wall lipids associated with virulence and latency; however, a mechanism of action is unclear.
