| Description | Brepocitinib (PF-06700841) is a potent dual JAK1/TYK2 inhibitor with IC50 values of 17 nM and 23 nM, respectively, and also inhibits JAK2 and JAK3 with IC50 values of 77 nM and 6.49 μM. |
| Targets&IC50 | TYK2:23 nM (cell free), JAK3:6.9 μM, JAK1:17 nM (cell free), JAK2:77 nM (cell free) |
| In vitro | PF-06700841 inhibits TYK2/JAK2 mediated IL-12/pSTAT4 and IL-23/pSTAT3 (human whole blood IC50s: 65/120 nM). PF-06700841 inhibits the JAK1/JAK3 driven γ-common chain cytokines, represented by IL-15/pStat5 and IL-21/pSTAT3 with reasonable potency (IC50s: 238/204 nM). PF-06700841 also has good potency against IL6/pStat1 in the CD3+ cellular subset (IC50: 81 nM), but lower inhibition of IL6/pSTAT3, again in the CD3+ cellular subset (IC50: 641 nM). PF-06700841 inhibits EPO/pSTAT5 (JAK2 homodimer) in HWB spiked with CD34+ progenitor cells (IC50: 577 nM). IL10/pSTAT3 (TYK2/JAK1) and IL27/pSTAT3 (JAK1/JAK2/TYK2) are also inhibited by PF-06700841 (IC50s: 305 nM/86 nM). |
| In vivo | PF-06700841 (3-30 mg/kg; p.o; 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 PF-06700841 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. |
