General description

A nitro-benzoxadiazole (NBD) compound that directly binds to the dimerization domain of sEGF receptor to generate stable dimers and allosterically activates the receptor. Exhibits similar phosphorylation profile as the cognate EGF-ligand. Enhances the phosphorylation of Tyr1068 and Tyr1173 in MDA-MB-468 cells in a time- and dose-dependent manner (EC50 = 52 µM with respect to Tyr1068). These phosphorylation events can be blocked by pre-incubating cells with AG1478 (>Cat. No. 658852; 10 µM) or PD153035 (https://www.emdmillipore.com/US/en/product/Complement-C9-Depleted-Serum-Human,EMD_BIO-234409">>Cat. No. 234490; 2 µM) that selectively block the ATP-binding pocket of EGFR. Tyr1068 phosphorylation of the receptor can also be completely blocked in EGF treated MDA-MB-468 cells exposed to anti-EGFR neutralizing antibody.
