Biological Activity

Baricitinib (formerly INCB28050, LY3009104) is a selective orally bioavailable JAK1/JAK2 inhibitor. Baricitinib preferentially inhibits JAK1 and JAK2, with 10-fold selectivity over Tyk2 and 100-fold over JAK3. INCB-28050 (baricitinib) inhibits intracellular signaling of multiple proinflammatory cytokines including IL-6 at concentrations <50 nM. Baricitinib also inhibits pSTAT3 stimulated by IL-23 with IC50 of 20 nM in isolated naive T-cells. Baricitinib (INCB028050) was also effective in multiple murine models of arthritis, with no evidence of suppression of humoral immunity or adverse hematologic effects. Baricitinib reduces levels of pSTAT3 in a dose- and time-dependent manner in the peripheral blood of rAIA animals. INCB28050 (Baricitinib) (10 mg/mL, p.o.) improves a composite score of joint damage by 47% in the murine CIA model.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)

Weight (kg) 0.02 0.15 1.8 0.4 0.08 10

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
