Description

Pelitinib (EKB-569) is a 3-cyanoquinoline pan-ErbB tyrosine kinase inhibitor with potential antineoplastic activity. Pelitinib irreversibly binds covalently to epidermal growth factor receptors, thereby inhibiting receptor phosphorylation and signal transduction and resulting in apoptosis and suppression of proliferation in tumor cells that overexpress these receptors. Pelitinib had been in phase II clinical trials for the treatment of non-small cell lung cancer and colorectal cancer. Treatment-emergent adverse events were diarrhea, abdominal pain, gastrointestinal carcinoma, intestinal obstruction and vomiting.

Sample Use Guides

In Vivo Use Guide
The maximum tolerated dose of EKB-569 is 75 mg once-daily.
Route of Administration: Oral
In Vitro Use Guide
Pelitinib has been found to exert a potent anti-proliferative activity against tumor cells overexpressing EGF-R, including NHEK, A431 and MDA-468 cells, with IC50 values of 61 nM, 125 nM and 260 nM respectively; while it has also been found to potently inhibit EGF-induced phosphorylated EGF-R (pEGF-R) in A431 and NHEK cells with IC50 values ranging from 20 nM to 80 nM.
