XMU-MP-5 is a new-generation potent and selective ALK inhibitor (IC50=4.15 nM) to overcome crizotinib resistance mutations, including L1196M and G1202R; XMU-MP-5 significantly induced apoptosis in EML4-ALK Ba/F3 cells did not affect apoptosis in wild-type Ba/F3 cells. XMU-MP-5 shows highest binding affinities for ALK and its mutants ALK(C1156Y) and ALK(L1196M), with K d values of 0.57, 0.4, and 0.77 nM, respectively. XMU-MP-5 blocks ALK signaling pathways and inhibits the proliferation of cells harboring either wild-type or mutant EML4-ALK in vitro and suppresses tumor growth in xenograft mouse models in vivo. XMU-MP-5 induces significant regression of lung tumors in two genetically engineered mouse (GEM) models.

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.
