AZ 7550 is an active metabolite of AZ 9291 (Item No. 16237).1 It inhibits the insulin-like growth factor 1 receptor (IGF-1R) in a cell-free assay (IC50 = 1.6 µM). It inhibits EGFR autophosphorylation in H1975 and PC-9 cells expressing the respective constitutively active mutants EGFRT790M/L858R and EGFRExon19del (IC50s = 0.045 and 0.026 µM, respectively), as well as in LoVo cells expressing wild-type EGFR (IC50 = 0.786 µM).
WARNING This product is not for human or veterinary use.
1. Discovery of a potent and selective EGFR inhibitor (AZD9291) of both sensitizing and T790M resistance mutations that spares the wild type form of the receptor. J. Med. Chem. 57(20), 8249-8267 (2014).
