Abstract

We describe the discovery of selective and potent Syk Inhibitor 11, which exhibited favorable PK profiles in rat and dog and was found to be active in a collagen-induced arthritis model in rats. Compound 11 was selected for further profiling, but, unfortunately, in GLP toxicological studies it showed liver findings in rat and dog. Nevertheless, 11 could become a valuable tool compound to investigate the rich biology of Syk in vitro and in vivo.
