Utatrectinib (AZD7451, AZ12607092) is a potent, selective, small molecule pan-Trk (NTRK) inhibitor with IC50 of 0.2-3.0 nM against TrkA, TrkB, and TrkC.Binding of AZD7451 to TrkA, TrkB, and TrkC would be expected to inhibit responses associated with NGF, BDNF, and NT3, respectively.AZD7451 completely blocked TrkC activation and associated tumorigenic behaviors at sub-micromolar concentrations in normal salivary gland tissue.AZD7451 showed efficacy and low toxicity in pre-clinical studies on adenoid cystic carcinoma (ACC) tumors engrafted in mice.AZD7451 potently inhibited in vitro growth and proliferation of the KM12 cell line harboring the NTRK1-fusion at 2 nM, AZD7451 inhibited proliferation of H460 cells at 5 nM, with TRKA phosphorylation inhibition.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C.
