 Use of Pelitinib


Pelitinib (EKB-569;WAY-EKB 569) is an irreversible inhibitor of EGFR with an IC50 of 38.5 nM; also slightly inhibits Src, MEK/ERK and ErbB2 with IC50s of 282, 800, and 1255 nM, respectively.

EGFR:38.5 nM (IC50)
In Vitro Pelitini has much greater inhibitory activity against the EGFR kinase than against Src, MEK/ERK, Cdk4, c-Met, Raf and ErbB2, for example, the IC50 for EGFR is 32-fold lower than the IC50 for the closely related ErbB2. Pelitinib results in a dramatic reduction in EGFR phosphorylation but no change in the total amount of EGFR protein. It requires at least 10-fold more drug to equivalently inhibit ErbB2 phosphorylation in similar assays, and EKB-569 does not block phosphorylation of another receptor tyrosine kinase (c-Met) assessed in the same manner[1]. EKB-569 is a potent inhibitor of proliferation in NHEK, A431, and MDA-468 cells (IC50=61, 125, and 260 nM, respectively) but not MCF-7 cells (IC50=3600 nM). EKB-569 is also a potent inhibitor of EGF-induced phosphorylated EGF-R (pEGF-R) in A431 and NHEK cells (IC50=20-80 nM)[1].
In Vivo A single oral dose of 10 mg/kg EKB-569 inhibits EGFR phosphorylation in A431 xenografts within 60 minutes. Twenty-four hours later, EGFR activity is still inhibited by over 50% by this single oral dose. The half-life of EKB-569 in mouse plasma is about 2 hours[1].
Cell Assay For experiments using cells in culture, A431 cells or 3T3/c-erbB-2 cells over-expressing c-erbB2 are are treated with various concentrations of EKB-569 for 2.75 h before co-incubation with 100 ng/mL EGF (A431 cells) or no growth factor (3T3/c-erbB-2 cells) for 0.25 h. Cells are ished twice with cold phosphate-buffered saline (PBS) before adding to lysis buffer for 20 min on ice, before immunoprecipitation and SDS–PAGE-immunoblotting[1].
Animal Admin Mice: For in vivo experiments, athymic nu/nu female mice are implanted subcutaneously with 5×106 A431 tumor cells. When tumors reach a mass of 200-300 mg, animals are treated with a single dose of 10 mg/kg EKB-569 in pH 2.0 water per gavage. Tumors from control and drug-treated animals are excised and minced into 1-mm pieces for anlysis[1].
