5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL PEG300, mix evenly to clarify it; add 50 μL Tween80 to the above system, mix evenly to clarify it; then continue to add 500 μL ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Clear solution
5% DMSO 95% corn oil
0.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 10 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* 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.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Sabutoclax (BI-97C1) is a pan-Bcl-2 inhibitor, including Bcl-xL, Bcl-2, Mcl-1 and Bfl-1 with IC50 of 0.31 μM, 0.32 μM, 0.20 μM and 0.62 μM, respectively.
Targets
Mcl-1 [1]
(Cell-free assay)		 Bcl-xL [1]
(Cell-free assay)		 Bcl-2 [1]
(Cell-free assay)		 Bfl-1 [1]
(Cell-free assay)
0.20 μM 0.31 μM 0.32 μM 0.62 μM
In vitro BI-97C1 potently inhibits cell growth of human prostate cancer, lung cancer, and lymphoma cell lines with EC50 values of 0.13, 0.56, and 0.049 μM, respectively, and shows little cytotoxicity against bax-/-bak-/- cells[1]. It is suggest that treatment with the combination regimen of mda-7/IL-24 and BI-97C1 induces autophagy that facilitates apoptosis in association with up-regulation of NOXA, accumulation of Bim, and activation of Bax and Bak[2].
In vivo BI-97C1 displays in vivo efficacy in transgenic mice in which Bcl-2 is overexpressed in splenic B-cells and also demonstrates superior single-agent antitumor efficacy in a prostate cancer mouse xenograft model that depends on Mcl-1 for survival[1]. Treatment with Ad.5/3-mda-7 and BI-97C1 significantly inhibits the growth of human PC xenografts in nude mice and spontaneously induced PC in Hi-myc transgenic mice. Tumor growth inhibition correlats with increased TUNEL staining and decreased Ki-67 expression in both PC xenografts and prostates of Hi-myc mice[2].

Protocol (from reference)

Kinase Assay:[1]
  • Competitive fluorescence polarization assays (FPA)

    A Bak BH3 peptide (F-BakBH3) (GQVGRQLAIIGDDINR) is labeled at the N-terminus with fluorescein isothiocyanate (FITC) and purified by HPLC. For competitive binding assays, 100 nM GST-Bcl-XL ΔTM protein is preincubated with the tested compound at varying concentrations in 47.5 μL PBS (pH = 7.4) in 96-well black plates at room temperature for 10 min, and then 2.5 μL of 100 nM FITC-labeled Bak BH3 peptide is added to produce a final volume of 50 μL. The wild-type and mutant Bak BH3 peptides are included in each assay plate as positive and negative controls, respectively. After 30 min incubation at room temperature, the polarization values in millipolarization units are measured at excitation/emission wavelengths of 480/535 nm with a multilabel plate reader. IC50 is determined by fitting the experimental data to a sigmoidal dose-response nonlinear regression model. Data reported are mean of three independent experiments. Performance of Bcl-2 and Mcl-1FPA are similar. Briefly, 50 nM of GST-Bcl-2 or -Mcl-1are incubatedwith various concentrations of compound (4 and 11-14) for 2 min, and then 15 nM FITC-conjugated-Bim BH3 peptide is added in PBS buffer. Fluorescence polarization is measured after 10 min.
