Discovery of Selective Irreversible Inhibitors for Bruton’s Tyrosine Kinase



original image

A series of highly selective irreversible inhibitors for Bruton's tyrosine kinase (Btk) was developed using a structural bioinformatics approach. Their capabilities to modulate Btk's activity were characterized both in vitro and in vivo. Oral treatment with once-a-day dosing of compound 4 greatly inhibited disease development in a rodent rheumatoid arthritis (RA) model.
