Brepocitinib (PF-06700841) P-Tosylate is a potent dual Janus kinase 1 (JAK1) and TYK2 inhibitor with IC50s of 17 nM and 23 nM, respectively. Brepocitinib P-Tosylate also inhibits JAK2 and JAK3 with IC50s of 77 nM and 6.49 μM, respectively[1].
Brepocitinib (Compound 23) potently inhibits TYK2/JAK2 mediated IL-12/pSTAT4 and IL-23/pSTAT3 (human whole blood (HWB) IC50s of 65 and 120 nM, respectively). Brepocitinib has good potency against IL6/pStat1 in the CD3+ cellular subset (IC50 of 81 nM), but lower inhibition of IL6/pSTAT3, again in the CD3+ cellular subset (IC50 of 641 nM). Brepocitinib also inhibits the JAK1/JAK3 driven γ-common chain cytokines, represented by IL-15/pStat5 and IL-21/pSTAT3 with reasonable potency (HWB IC50s of 238 and 204 nM, respectively). Brepocitinib inhibits EPO/pSTAT5 (JAK2 homodimer) in HWB spiked with CD34+ progenitor cells (IC50 of 577 nM). IL10/pSTAT3 (TYK2/JAK1) and IL27/pSTAT3 (JAK1/JAK2/TYK2) are also inhibited by Brepocitinib with IC50s of 305 nM and 86 nM, respectively[1].
Brepocitinib (Compound 23; 3-30 mg/kg; oral administration; for 7 consecutive days; female Lewis rats) treatment significantly reduces paw volume increase in a dose-dependent manner. The plasma concentrations in animals dosed with Brepocitinib at peak (30 min) and trough (24 h) time intervals post final dose respectively are as follows: 3 mg/kg, 3.54 μM, 0.0221 μM; 10 mg/kg, 10.95 μM, 0.06 μM; and 30 mg/kg, 23.89 μM, 0.06 μM[1].
