2.8 nM	3.3 nM

In Vitro
In vitro	INCB018424 potently and selectively inhibits JAK2V617F-mediated signaling and proliferation in Ba/F3 cells and HEL cells. INCB018424 markedly increases apoptosis in a dose dependent manner in Ba/F3 cells. INCB018424 (64 nM) results in a doubling of cells with depolarized mitochondria in Ba/F3 cells. INCB018424 inhibits proliferating of erythroid progenitors from normal donors and polycythemia vera patients with IC50 of 407 nM and 223 nM, respectively. INCB018424 demonstrates remarkable potency against erythroid colony formation with IC50 of 67nM. ^[1]
Kinase Assay	Binding assay
Kinase Assay	Recombinant proteins are expressed using Sf21 cells and baculovirus vectors and purified with affinity chromatography. JAK kinase assays use a homogeneous time-resolved fluorescence assay with the peptide substrate (-EQEDEPEGDYFEWLE). Each enzyme reaction is carried out with Ruxolitinib or control, JAK enzyme, 500 nM peptide, adenosine triphosphate (ATP; 1mM), and 2% dimethyl sulfoxide (DMSO) for 1 hour. The 50% inhibitory concentration (IC50) is calculated as INCB018424 concentration required for inhibition of 50% of the fluorescent signal.

	反応時間	48 hours
	実験の流れ	Cells are seeded at 2 × 10³/well of white bottom 96-well plates, treated with INCB018424 from DMSO stocks (0.2% final DMSO concentration), and incubated for 48 hours at 37 ℃ with 5% CO₂. Viability is measured by cellular ATP determination using the Cell-Titer Glo luciferase reagent or viable cell counting. Values are transformed to percent inhibition relative to vehicle control, and IC50 curves are fitted according to nonlinear regression analysis of the data using PRISM GraphPad.

In Vivo
In Vivo	INCB018424 (180 mg/kg, orally, twice a day) results in survive rate of greater than 90% by day 22 in a JAK2V617F-driven mouse model. INCB018424 (180 mg/kg, orally, twice a day) markedly reduces splenomegaly and circulating levels of inflammatory cytokines, and preferentially eliminated neoplastic cells, resulting in significantly prolonged survival without myelosuppressive or immunosuppressive effects in a JAK2V617F-driven mouse model. ^[1] The primary end point is reached in 41.9% of patients in the Ruxolitinib group as compared with 0.7% in the placebo group in the double-blind trial of myelofibrosis. Ruxolitinib results in maintaining of reduction in spleen volume and improvement of 50% or more in the total symptom score. ^[2] A total of 28% of the patients in the Ruxolitinib (15 mg twice daily) group has at least a 35% reduction in spleen volume at week 48 in patients with myelofibrosis, as compared with 0% in the group receiving the best available therapy. The mean palpable spleen length has decreased by 56% with Ruxolitinib but has increased by 4% with the best available therapy at week 48. Patients in the ruxolitinib group has an improvement in overall quality-of-life measures and a reduction in symptoms associated with myelofibrosis. ^[3]

よくある質問（FAQ）

質問1:
What is the difference between S2902 and S1378 which seem to have same structure formula according to the product information?

回答
These two chemicals are the two different chiral forms of Ruxolitinib. S2902 S-Ruxolitinib is the S form and S1378 Ruxolitinib is the D form. One of the carbon atoms in this molecule is asymmetric, making the two molecules mirror images of each other. The biological activities of these two molecules can be very different because of the confirmation differences.

質問2:
How about the half-life of the compound (Ruxolitinib)? How long is the duration of the inhibitory effect on JAK-STAT signaling?

回答
The half-life of this compound in body is about 2~3 hours according to previous study. Generally, it is longer in vitro culture medium than in vivo. In paper, Ruxolitinib was also used for 24hours. http://www.bloodjournal.org/cgi/pmidlookup?view=long&pmid=24711661.
