Description

CEP-33779 is a novel, selective, and orally bioavailable inhibitor of JAK2 with an IC50 of 1.8±0.6 nM.

IC50 & Target[1]

JAK2

1.8 nM (IC50)

JAK3

150 nM (IC50)

In Vitro

CEP-33779, at nontoxic concentrations, significantly sensitizes overexpression of P-glycoprotein overexpressing multidrug resistance cells to its anticancer substrates. CEP-33779 significantly increases intracellular accumulation and decreases the efflux of doxorubicin by inhibiting the overexpression of P-glycoprotein transport function[3].

In Vivo

CEP-33779 exhibits a favorable PK profile in nude mice, an iv half-life of 1 h, moderate distribution (Vd=2.6 L/kg), and measurable oral exposure with an estimated bioavailability of 33%. It demonstrates antitumor efficacy in the CWR22 xenograft model; oral dosing for 14 days at 30 mg/kg bid results in tumor stasis and partial regressions in 5/10 animals[1]. CEP-33779 administration results in an almost complete shrinkage of tumors in most animals; few remaining tumor nodules were small, poorly vascularized, and had a necrotic appearance. CEP-33779 suppressed activation of NF-κB in tumors[2].

Kinase Assay
[1]

The kinase activity of baculovirus-expressed human JAK1, JAK2, or JAK3 is measured. Each 96-well Costar high binding plate is coated with 100 μL/well of 10 μg/mL neutravidin in TBS at 37 °C for 2 h, followed by 100 μL/well of 1 μg/mL 15-mer peptide substrate at 37 °C for 1 h. The kinase assay mixture (total volume=100 μL/well) consisting of 20 mM HEPES (pH 7.2), ATP (0.2 μM ATP for JAK1 and JAK2 and 0.1 μM ATP for JAK3), 1 mM MnCl2, 0.1% BSA, and CEP-33779 (diluted in DMSO, 2.5% DMSO final in assay) is added to the assay plate. Enzyme is added and the reaction is allowed to proceed for 20 min at room temperature. Detection of the phosphorylated product is performed by adding 100 μL/well of diluted Eu-N1 labeled PY100 antibody. Samples are incubated at RT for 1 h, followed by addition of 100 μL enhancement solution. Plates are agitated for 10 min, and the fluorescence of the resulting solution is measured. IC50 values are determined[1].

Animal Administration
[1]

Mice: Nude mice bearing CWR22 xenografts are dosed orally with 55 mg/kg of CEP-33779 or a vehicle (PEG400). At 2, 6, and 24 h after dosing animals (3/group) are sacrificed, tumors are excised and plasma samples are prepared. Tumor extracts are prepared using Triton-based extraction buffer supplemented with inhibitors of proteases and phosphatases. Equal amounts of extracts are resolved on SDS-PAGE gels and STAT3 phosphorylation and expression are analyzed by Western blot using specific antibodies[1].
