Tesevatinib (XL-647) potently inhibits the EGF/ErbB2, VEGF, and ephrin RTK families. Tesevatinib (XL-647) is a reversible and ATP competitive inhibitor. Tesevatinib (XL-647) was inactive against a panel of 10 tyrosine kinases (including the insulin and the insulin-like growth factor-1 receptor) and 55 serine-threonine kinases (including cyclin-dependent kinases, stress-activated protein kinases, and protein kinase C isoforms). Tesevatinib (XL-647) inhibits cellular proliferation and EGFR pathway activation in the erlotinib-resistant H1975 cell line that harbors a double mutation (L858R and T790M) in the EGFR gene. In A431 cells, Tesevatinib (XL-647) reduces cell viability with IC50 values of 13 nM. has not independently confirmed the accuracy of these methods. They are for reference only.

Tesevatinib (XL-647) shows potent and long-lived inhibition of the WT EGFR in vivo. Tesevatinib (XL-647) substantially inhibits the growth of H1975 xenograft tumors and reduces both tumor EGFR signaling and tumor vessel density. has not independently confirmed the accuracy of these methods. They are for reference only.
