ZH97 is a selective and covalent small-molecule inhibitor of BFL-1 protein with binding Ki of 0.41 uM, >200-fold selectivity over MCL-1.ZH97 does not bind to BCL-xL, BCL-2, TEAD2, TEAD4, MDM2, MDMX, BRD2 BD1, BRD2 BD2, BRD3 BD1, BRD3 BD2, BCL9, PD1/PD-L1 (Ki>400 uM).ZH97 modifies BFL-1 at the C55 residue, blocks BFL-1/BID interaction in vitro.ZH97 dose-dependently increased cytoplasmic cytochrome c level in U937 cells, has cell growth inhibition with IC50 of 2.8 uM, 5.5 uM, 7.7 uM, 6.8 uM, and 3.9 uM in U937, Kasumi-1, K562, MM.1S, and MV4-11 cell lines, respectively.ZH97 inhibits BFL-1/PUMA interaction in cell lysate and is effective in cancer cells that harboring highexpression level of BFL-1.

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.
