AUY922 (NVP-AUY922) is a potent and selective inhibitor of HSP90[1], effectively inhibiting both HSP90α and HSP90β with similar IC50 values of 13nM and 21nM, respectively[2]. AUY922 (NVP-AUY922) exhibits significant antitumor activity and is commonly utilized in the research of various cancers, including breast cancer, lung cancer[3], and gastrointestinal stromal tumors[4].
AUY922 (NVP-AUY922) inhibited the in vitro proliferation of human tumor cells, which selected for their different tissue origins and molecular features with nanomolar potency (2.3–49.6nmol/L) [5]. AUY922 (NVP-AUY922) (100, 500, 1000nM; 5, 15, 30, 60, 180min) treatment can induce HSP90-p23 dissociation and client protein depletion in a concentration and time dependent manner in BT-474 cells[6].
AUY922 (NVP-AUY922) (50, 75mg/kg) slowed growth of A549 (KRAS-mutant) xenografts and achieved tumor stability and decreased EGF receptor (EGFR) protein expression in H1975 xenografts model mice[7]. AUY922 (NVP-AUY922) (30mg/kg) combined with radiation treatment delayed tumor growth in a supra-additive manner in tumor xenograft model mice[8].
