Biological Activity

INCB18424 (Ruxolitinib), the most advanced JAK-1 and JAK-2 inhibitor, is in Phase III testing to treat myelofibrosis. INCB18424 demonstrated potent in vitro cellular activity (100-130 nM) in an engineered Ba/F3 cell line harboring the JAK2V617F mutation and EPO-independent erythroid colony growth of precursor cells from PV patients (IC50 of 67 nM) while showing lesser effect on normal colony formation from healthy donors (IC50 > 400 nM).

Protocol
Cell Experiment
Cell lines Ba/F3-EpoR-JAK2V617F and HEL cell lines
Preparation method Cell proliferation assay. Cells were seeded at 2000/well of white bottom 96-well plates, treated with compounds from DMSO stocks (0.2% final DMSO concentration), and incubated for 48 hours at 37°C with 5% CO2. Viability was measured by cellular ATP determination using the Cell-Titer Glo (Promega) luciferase reagent or viable cell counting. Values were transformed to percent inhibition relative to vehicle control, and IC50 curves were fitted according to nonlinear regression analysis of the data using PRISM GraphPad.
Concentrations 0~10 µ M
Incubation time 48 h
Animal Experiment
Animal models myeloproliferative neoplasm mouse model
Formulation 5% dimethyl acetamide, 0.5% methocellulose
Dosages 180mg/kg began within 24 hours of cell inoculation, twice daily
Administration oral gavage
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
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.
