- Design, synthesis and evaluation of novel 5-phenylpyridin-2(1H)-one derivatives as potent reversible Bruton's tyrosine kinase inhibitors
-
A series of novel reversible Btk inhibitors has been designed based on the structure of the recently reported preclinical drug RN486. The synthesis and SAR of these compounds are described. Among these derivatives, compound 16b was identified to be a potent and orally available reversible agent with satisfactory Btk enzymatic and cellular inhibition in vitro, as well as favorable PK properties and inhibition of arthritis in vivo.

- Structure-based drug design of RN486, a potent and selective Bruton's tyrosine kinase (BTK) inhibitor, for the treatment of rheumatoid arthritis
-
Structure-based drug design was used to guide the optimization of a series of selective BTK inhibitors as potential treatments for Rheumatoid arthritis. Highlights include the introduction of a benzyl alcohol group and a fluorine substitution, each of which resulted in over 10-fold increase in activity. Concurrent optimization of drug-like properties led to compound 1 (RN486) (J. Pharmacol. Exp. Ther. 2012, 341, 90), which was selected for advanced preclinical characterization based on its favorable properties.
