CXF-009 is a potent, specific, dual-warhead covalent inhibitor of FGFR4 (IC50=48 nM), forms dual-warhead covalent bonds with two cysteine residues in FGFR4.CXF-009 forms covalent bonds with FGFR4(C477A) and FGFR4(C552A), respectively; display weak inhibition against FGFR1-3 with IC50 of 2579 nM, 2408 nM, and 977 nM.CXF-009 shows inhibitory effect agaginst FGFR4 muntants FGFR4(C477A), FGFR4(C552A), and FGFR4(C477A, C552A) with IC50 of 193 nM, 602 nM, and 1528 nM, respectively.CXF-009 inhibited the growth of Ba/F3 cells transformed with FGFR1-4 with IC50 values of 1562 nM, 1971 nM, 777 nM, and 38 nM, respectively.CXF-009 is slightly more reactive to GSH than PRN1371.

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.
