153436-54-5

Yellowish solid

PD153035 is an inhibitor of EGFR, competitive with ATP. EGF Receptor: IC50 = 25 pM (Ki = 6 pM).

ChEBI: A member of the class of quinazolines carrying a 3-bromophenylamino substituent at position 4 and two methoxy substituents at positions 6 and 7.

An extremely potent inhibitor of epidermal growth factor (EGF) receptor tyrosine kinase, with an IC 50 of 25 pM. Inhibits other purified tyrosine kinases only at micromolar or higher concentrations.

AG-1517 HCl (153436-54-5) is an ultra-potent inhibitor of epidermal growth factor receptor tyrosine kinase (EGFR), with an IC50 of 25 pM. Inhibits other tyrosine kinases at micromolar or higher concentrations. It selectively blocks EGF-mediated cellular processes including mitogenesis, early gene expression and oncogenic transformation.1?Inhibits the growth of a number of cancer cell lines.2?AG-1517 HCl is an extremely useful tool for exploring EGF-mediated cellular signaling.3

GENERAL METHOD: 4-Chloro-6,7-dimethoxyquinazoline (1 mmol) was dissolved in refluxing 2-propanol (20 mL) and m-bromoaniline (1 mmol) was added dropwise. The reaction mixture was refluxed for 3-4 hours and the progress of the reaction was monitored by TLC until completion. Upon completion of the reaction, the precipitate was filtered out and washed sequentially with 2-propanol (10 mL) and ether (10 mL). If no precipitate formation was observed, the solvent was removed under reduced pressure to obtain a solid product. The final product was purified by recrystallization from 75% ethanol solution.
