Based on 2 publication(s) in Google Scholar
CL-387785 (EKI-785; WAY-EKI 785) is an orally active EGFR inhibitor with an IC50 of 370 pM. CL-387785 inhibits EGF-stimulated EGFR autophosphorylation with an IC50 of approximately 5 nM. CL-387,785 exerts selective inhibition on cell lines overexpressing EGFR or c-erbB-2, whereas it shows weak inhibitory effects on cell lines with low expression of these two receptors. CL-387785 effectively induces cell cycle arrest and apoptosis. CL-387785 can be used for the research of non-small cell lung cancer and autosomal recessive polycystic kidney disease.
