Potentiation of the antitumor effects of vincristine by CEP-33779 in a KBv200 cell xenograft model in nude mice. (A) The changes in tumor volume with time after tumor cell implantation. (B) The photograph of tumor size was taken on the 21st day after implantation. The various treatments were as follows: (a) Control (vehicle alone); (b) Vincristine (q2d x 6, ip, 0.2 mg/kg); (c) CEP-33779 (q2d x 6, p.o, 30 mg/kg) and (d) Vincristine (q2d x 6, ip, 0.2 mg/kg) plus CEP-33779 (q2d ?6, p.o, 30 mg/kg, given an hour before Vincristine administration).

IL-17A secretion from CD4+ T cells cultured under Th17-promoting conditions in-vitro in the presence of JAK inhibitors (Tofa, JAK3 > JAK1/2; Ruxo, JAK2 > JAK1; Bari, JAK1/2 > TYK2; CEP, JAK2) from day 0 to 3. Measured by supernatant ELISA and normalized to DMSO control (=100%) on day 3 (no.s AS = 43/Bari = 10, HC = 26/Bari = 14, PSA = 16/Bari = 3 and RA = 18/Bari = 9).

CEP-33779 does not disorder microtubules reorganization in mouse oocytes. Metaphase I(M I) spindle morphology of mouse oocytes were observed during meiosis in control (n=77), DMSO (n=83), and CEP-33779 (n=72) groups. DNA (blue) and tubulin (green) were stained with DAPI and antitubulin antibody, respectively. The scale bar is 20 μm.

|Description||CEP33779 is a selective JAK2 inhibitor with IC50 of 1.8 nM, >40- and >800-fold versus JAK1 and TYK2.|
CEP33779(< 3 μM) inhibits phosphorylation of downstream target signal transducer and activator of transcription 5(pSTAT5) of JAK2 in a concentration dependent manner in HEL92 cells. 
|In vivo||CEP33779 orally administrated with 55 mg/kg inhibits phosphorylation of STAT5 in HEL92 tumor extracts from HEL92 xenograft mice. CEP33779 orally administered twice daily at dose of 55 mg/kg reduces mean paw edema and clinical scores in mice with collagen-antibody induced arthritis (CAIA) or collagen-induced arthritis (CIA). CEP33779 orally administered twice daily at dose of 55 mg/kg totally inhibits paw phospho-STAT3 expression in CAIA or CIA mice, associated with decreased cytokines including IL-12, IFNγ, IL-2, IL-1β, TNFα and GM-CSF. CEP33779 results in reduced bone degradation, reduced tissue destruction, and reduced osteoarthritis in dose-dependent manner in CAIA or CIA mice.  CEP33779 orally administrated at 100 mg/kg extends survival and reduces splenomegaly/lymphomegaly in MRL/lpr systemic lupus erythematosus mice, thus protect mice from developing glomerulonephritis. CEP33779 orally administrated at 100 mg/kg decreases several SLE-associated proinflammatory cytokines and reduces levels of a bone resorption biomarker associated with increased osteoclast activity in MRL/lpr systemic lupus erythematosus mice.  CEP33779 orally administered twice daily at dose of 55 mg/kg induces regression of established colorectal tumors, reduces angiogenesis, and reduces proliferation of tumor cells in a mouse model of colitis-induced colorectal cancer. Tumor regression correlated with inhibition of STAT3 and NF-κB (RelA/p65) activation, and decreased the expression of proinflammatory, tumor-promoting cytokines interleukin (IL)-6 and IL-1β. |
|In vitro||DMSO||36 mg/mL (77.82 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
1% DMSO+30% PEG 300+1% Tween 80
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Frequently Asked Questions
How to formulate the compound for in vivo use?
S2806 in 1% DMSO+30% polyethylene glycol+1% Tween 80 is a suspension. It is fine for oral gavage, and can be further dilute with PBS. PEG 400 is ok.
