ABT-263 also called Navitoclax is a potent and orally bioavailable Bcl-2 family inhibitor (Ki's of <1 nmol/L for Bcl-2, Bcl-xL, and Bcl-w). it maintains a high affinity for Bcl-xL, Bcl-2, and Bcl-w, (Ki ≤1 nmol/L), but binds more weakly to Mcl-1 and A1.

METHODS: Mouse primary B lymphocytes FL5.12/Bcl-xL and FL5.12/Bcl-2 were treated with Navitoclax (0.001-1000 nmol/L) for 48 h. Cell viability was measured using the CellTiter Glo. RESULTS: Navitoclax reversed the protection afforded by overexpression of Bcl-2 or Bcl-xL (EC50 of 60 and 20 nmol/L, respectively). In the presence of IL-3, Navitoclax was ineffective in inducing cell death in the absence of pro-apoptotic stimuli in FL5.12 cells. [1] METHODS: HCC cells PLC/PRF/5, Hep3B, HepG2, and Huh7 were treated with Navitoclax (5 μM) for 18 h, and the expression levels of target proteins were detected by Western Blot. RESULTS: After treatment with Navitoclax, Mcl-1 levels were significantly increased in all HCC cell lines, but Bcl-2 and B cl-xL levels did not change significantly. [2]
Store lyophilized at -20ºC, keep desiccated. In lyophilized form, the chemical is stable for 36 months. In solution, store at -20ºC and use within 1 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles.
