JBJ-08-178-01 is a potent, selective and covalent HER2 inhibitor with IC50 of 2.21 nM and 7.04 nM for HER2 WT and EGFR WT, targets multiple HER2 activating mutations, including exon 20 insertions as well as amplification (IC50 values<50 nM).JBJ-08-178-01 maintained potency against non-insertion mutations, including S310F, L755S, V777L, V842I, and exon 19 indel (755_757LREdelinsRP) of HER2.JBJ-08-178-01 exhibited a much greater degree of HER2-selectivity in Ba/F3 cell lines than in biochemical assays, owing to weak growth inhibition against Ba/F3 cells with WT EGFR (IC50=368 nM).JBJ-08-178-01 showed strong antitumoral activity in HER2- mutant or amplified cancers in vitro and in vivo.Treatment with JBJ-08-178-01 also led to a reduction in total HER2 by promoting proteasomal degradation of the receptor.JBJ-08-178-01 is a selective, dual-action inhibitor and destabilizer of HER2 with potential efficacy and tolerance against NSCLC harboring HER2 genetic alterations or amplification.

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. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
