XL-647

Research use only, not for human use.

XL-647 (Tesevatinib, EXEL-7647, KD-019) is a novel spectrum-selective kinase inhibitor that potently inhibits the EGFR, ErbB2, KDR and EphB4 with IC50 of 0.3, 16, 1.5 and 1.4 nM, respectively.

XL-647 (Tesevatinib, EXEL-7647, KD-019) is a novel spectrum-selective kinase inhibitor that potently inhibits the EGFR, ErbB2, KDR and EphB4 with IC50 of 0.3, 16, 1.5 and 1.4 nM, respectively; shows no inhibition on IGF1R and InsR, also is inactive against a panel of 55 serine-threonine kinases (including CDKs, stress-activated protein kinases, and PKC isoforms; inhibits WT and mutant EGFR phosphorylation in cells with IC50 of 5 and 74 nM, inhibits mutant EGFR resistant to gefitinib and erlotinib, inhibits cellular proliferation and EGFR pathway activation in the erlotinib-resistant H1975 cell line that harbors double mutation L858R/T790M; inhibits H1975 xenograft tumors and reduces both tumor EGFR signaling and tumor vessel density in vivo.Lung Cancer Phase 3 Clinical.

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.

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.
