ABSTRACT
|
|
|
| |
|
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.
