Erlotinib (CP-358774) is a selective, orally active EGFR tyrosine kinase inhibitor. Erlotinib also acts as a substrate and inhibitor of OATP2B1, with an IC50 of approximately 0.079 μM for inhibiting OATP2B1-mediated uptake of estrone 3-sulfate. Erlotinib blocks EGFR phosphorylation, downstream signal transduction, as well as the growth and proliferation of cancer cells. Erlotinib inhibits MMP-10-mediated renal injury, fibrotic lesions, the ERK1/2, GSK-3β and β-catenin signaling pathways, fibronectin, α-SMA, collagen deposition, and renal injury markers. Erlotinib is metabolized via CYP3A to produce the active metabolite OSI-420. Erlotinib can be used in research related to non-small cell lung cancer, gastric cancer, papillary renal cell carcinoma, pancreatic cancer, renal fibrosis, and other conditions .
