生物活性
PF-06700841 is a potent dual Janus kinase 1 (JAK1) and TYK2 inhibitor with IC50s of 17 nM and 23 nM, respectively. PF-06700841 also inhibits JAK2 and JAK3 with IC50s of 77 nM and 6.49 μM, respectively. PF-06700841 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). PF-06700841 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). PF-06700841 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 PF-06700841 with IC50s of 305 nM and 86 nM, respectively.
In vivo, PF-06700841 (3-30 mg/kg; oral administration; for 7 consecutive days; female Lewis rats) treatment significantly reduces paw volume increase in a dose-dependent manner.

不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南）
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
| 重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| 体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
| 动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
| 动物 A的Km系数 |
例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
