Biological Activity for ABT 263

ABT 263 is a high affinity inhibitor of Bcl-2 family proteins (K_i values are 0.5 nM, <1 nM and <1 nM in Bcl-xL, Bcl-2 and Bcl-W respectively). ABT 263 induces G₁/G₀ phase arrest, apoptosis and autophagy in cancer cells in vitro (IC₅₀ = 3.4 - 12 μM). In vivo, ABT 263 displays a synergistic antitumor effect with rituximab and Bortezomib (Cat. No. 7282), Docetaxel (Cat. No. 4056) and Erlotinib (Cat. No. 7194), and inhibits growth of SCLC xenografts when combined with (+)-JQ1 (Cat. No. 4499). ABT 263 also reduces inflammation and viral-induced senescence in SARS-CoV-2 infection in vivo, and clears senescent cells and rejuvenates aging stem cells. Orally bioavailable.
