BSJ-04-122 is a potent, selective, covalent dual MKK4/7 inhibitor with IC50 of 4/181 nM, displays excellent kinome selectivity; BSJ-04-122 covalently targets a conserved cysteine (Cys247 for MKK4, and Cys261 for MKK7) located before the DFG motif. SJ-04-122 exhibits potent cellular target engagement and induces robust target-specific downstream effects. In breast cancer cell lines, BSJ-04-122 potently inhibited JNK phosphorylation, BSJ-04-122 significantly decreased levels of T183/Y185 pJNK at 5 uM, resulting in complete inhibition at 10 uM in MDA-MB-231 cells. The combination of the dual MKK4/7 inhibitor BSJ-04-122 with a selective, covalent JNK inhibitor (JNK-IN-8) demonstrated an enhanced antiproliferative activity against triple-negative breast cancer cells.

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.
