Cyclopropanecarboxylic acid-(3-(6-(3-trifluoromethyl-phenylamino)-pyrimidin-4-ylamino)-phenyl)-amide Off-white solid. PROTECT FROM LIGHT. PACKAGED UNDER INERT GAS. A cell-permeable 4,6-dianilinopyrimidine compound that acts as a potent, ATP-competitive, and highly selective inhibitor of EGFR and some EGFR mutants (IC50 = 21 nM, 63 nM, and 4 nM for EGFRwt, EGFRL858R and EGFRL861Q, respectively) vs. erbB4/Her4 (IC50 = 7.64 µM) and a panel of 55 other kinases. Shown to completely block EGF-induced EGFR autophosphorylation in U-2OS cells at 10 µM. Purity: ≥97% by HPLC. CAS 879127-07-8. Ref.: Zhang, Q., et al. 2006. J. Am. Chem. Soc. 128, 2182 |
