PF-303 is a highly selective, oral inhibitor of Bruton's tyrosine kinase (BTK) with an IC50 of 0.64 nM. This compound forms a reversible covalent bond with the Cys481 residue of BTK, allowing for targeted modulation of BTK activity without the concerns associated with irreversible inhibitors. PF-303 is valuable for investigating the role of BTK in immune system functioning, particularly in analyzing B-cell subsets, antibody production, and T-cell activation dynamics.
