Biological Activity

Description Venetoclax (ABT-199, GDC-0199) is a Bcl-2-selective inhibitor with Ki of <0.01 nM in cell-free assays, >4800-fold more selective versus Bcl-xL and Bcl-w, and no activity to Mcl-1. Venetoclax is reported to induce cell growth suppression, apoptosis, cell cycle arrest, and autophagy in triple negative breast cancer MDA-MB-231 cells. Phase 3.
Targets
Bcl-2 [1]
(Cell-free assay)
<0.01 nM(Ki)
In vitro ABT-199 shows less sensitivity to Bcl-xL, Mcl-1 and Bcl-w with Ki of 48 nM, > 444 nM and 245 nM, respectively. ABT-199 potently inhibits FL5.12-Bcl-2 cells, RS4;11 cells with EC50 of 4 nM and 8 nM, while shows low activity against FL5.12-Bcl-xL cells with EC50 of 261 nM. ABT-199 induces a rapid apoptosis in RS4;11 cells with cytochrome c release, caspase activation, the externalization of phosphatidylserine and the accumulation of sub-G0/G1 DNA. Quantitative immunoblotting reveals that sensitivity to ABT-199 correlated strongly with the expression of Bcl-2, including NHL, DLBCL, MCL, AML and ALL cell lines. ABT-199 also induces apoptosis in CLL with an average EC50 of 3.0 nM. [1]
In vivo ABT-199 (100 mg/kg) causes a maximal tumor growth inhibition of 95% and tumor growth delay of 152% in RS4;11 xenografts. ABT-199 also inhibits xenograft growth (DoHH2, Granta-519) as a single agent or in combination with SDX-105 and other agents. [1]
Features Re-engineered version of ABT-263 (Navitoclax).

Protocol (from reference)

Kinase Assay:[1]
  • Binding affinity assays

    Binding affinities (Ki or IC50) of ABT-199 against different isoforms of Bcl-2 family are determined with competitive fluorescence polarization assays. The following peptide probe/protein pairs are used: f-bad (1 nM) and Bcl-xL (6 nM), f-Bax (1 nM) and Bcl-2 (10 nM), f-Bax (1 nM) and Bcl-w (40 nM), f-Noxa (2 nM) and Mcl-1 (40 nM), and f-Bax (1 nM) and Bcl-2-A1 (15 nM). Binding affinities for Bcl-xL are also determined using a time-resolved fluorescence resonance energy transfer assay. Bcl-xL (1 nM, His tagged) is mixed with 200 nM f-Bak, 1 nM Tb-labeled anti-His antibody, and ABT-199 at room temperature for 30 min. Fluorescence is measured on an Envision plate reader using a 340/35 nm excitation filter and 520/525 (f-Bak) and 495/510 nm (Tb-labeled anti-His antibody) emission filters.
Cell Assay:[1]
  • Cell lines

    NHL, DLBCL, MCL, AML and ALL cell lines

  • Concentrations

    ~1 μM

  • Incubation Time

    48 hours

  • Method

    RS4;11 cells are seeded at 5 × 104 per well in 96-well plates and treated with ABT-199 diluted in half-log steps starting at 1 μM-0.05 nM. Leukemia and lymphoma cell lines are seeded at 1.5-2 × 104 cells per well in the appropriate medium and incubated with ABT-199 for 48 h. Effects on proliferation are determined using Cell TiterGlo reagent. EC50 values are determined by nonlinear regression analysis of the concentration-response data.
Animal Study:[1]
  • Animal Models

    Female C.B-17 SCID mice (DoHH2 and Granta-519 xenografts) and female C.B-17 SCID-beige mice (RS4;11 and Toledo xenografts)

  • Dosages

    ~100 mg/kg

  • Administration

    Orally
