|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. Phase 3.|
|Features||Re-engineered version of ABT-263 (Navitoclax).|
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. 
|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. |
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.
|In vitro||DMSO||100 mg/mL warmed (115.14 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
5% DMSO+50% PEG 300+5% Tween 80+ddH2O
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
