PRN1008 Usage And Synthesis
Uses
Rilzabrutinib (PRN1008) is a reversible covalent, selective and oral active inhibitor of Bruton’s Tyrosine Kinase (BTK), with an IC50 of 1.3 nM.
in vivo
In vivo Rilzabrutinib demonstrates enduring pharmacodynamic effects after the compound has cleared from circulation, consistent with extended target residence time. Rilzabrutinib also reverses and completely suppresses collagen-induced arthritis in rats in a dose dependent manner which allows correlation of target occupancy and disease modification[2].
IC 50
BTK: 1.3 nM (IC50); BMX: 1.0 nM (IC50); ITK: 440 nM (IC50); TEC: 0.8 nM (IC50); RLK: 1.2 nM (IC50); BLK: 6.3 nM (IC50); EGFR: 520 nM (IC50); ERBB2: 3900 nM (IC50); ERBB4: 11.3 nM (IC50)
