U87 and A172 cells were treated with UMI-77 (8 μM) for 24h and further treated with TRAIL (30 ng/ml) for indicated period of time. Levels of apoptosis-associated proteins were analyzed by Western blot. GAPDH was used as a loading control.

(a) SVEC cells stably expressing FLAG-tBID 2A GFP-BCL-xL, FLAG-tBID 2A GFP-BCL-2 or FLAG-tBID 2A GFP-MCL-1 were transiently transfected with NOXA. Cell viability was analysed 24 h post-transfection by SYTOX Green dye exclusion and live-cell imaging using an IncuCyte imager. Error bars represent the s.e.m. of three independent experiments. (b) SVEC cells stably expressing FLAG-tBID 2A GFP-MCL-1 (MCL-1-dependent line) were treated with increasing concentrations of putative MCL-1 inhibitors UMI-77 or A-1210477. Cell viability was analysed 24 h post-treatment by SYTOX Green dye exclusion and live-cell imaging using an IncuCyte imager. Error bars represent the s.e.m. of three independent experiments. (c) MCL-1-dependent line was treated with UMI-77 or A-1210477 (both 10 μmol l−1) and analysed over time for cell viability by SYTOX Green dye exclusion and live-cell imaging using an IncuCyte imager. Error bars represent the s.e.m. of three independent experiments. (d,e) SVEC cells stably expressing FLAG-tBID 2A GFP-BCL-xL, FLAG-tBID 2A GFP-BCL-2 or FLAG-tBID 2A GFP-MCL-1 were treated with UMI-77 or A-1210477 (10 μM for 24 h) then cell viability was analysed by SYTOX Green dye exclusion and live-cell imaging using an IncuCyte imager (d) or by clonogenic survival assay (e). Error bars represent the s.e.m. of three independent experiments for d and s.d. of triplicate samples from a representative experiment carried out twice independently for e. In all cases, cells were treated with MCL-1 inhibitors in 3% FBS containing DMEM.

MCL-1 pharmacological inhibitor UMI-77 induces apoptosis of ESCC cells. a, b KYSE150 (a) and KYSE510 (b) cells were starved in 0.1% FBS/RPMI 1640 medium overnight and then cultured without (DMSO) or with different concentrations of UMI-77 in 10% FBS/RPMI 1640 medium for 48 h. After treatment, attached and floating cells were harvested. Cleavage of caspase-3 and PARP were analyzed by Western blotting. β-actin was used as a loading control. c KYSE150 and KYSE510 cells were starved in 0.1% FBS/RPMI 1640 medium overnight and then cultured without (DMSO) or with 10 μM UMI-77 in 10% FBS/RPMI 1640 medium for 48 h. After treatment, attached and floating cells were harvested. Cleavage of PARP was analyzed by Western blotting. β-actin was used as a loading control. Arrow head: 17KD or 19 KD of cleaved caspase-3

|Description||UMI-77 is a selective Mcl-1 inhibitor with Ki of 490 nM, showing selectivity over other members of Bcl-2 family.|
UMI-77 effectively disrupts the interactions between BL-Noxa and cellular Mcl-1, as well as Mcl-1/Bax protein–protein interactions.  UMI-77 inhibits growth of pancreatic cancer cells with IC50 of 3.4, 4.4, 12.5, 16.1, and 5.5 μM for BxPC-3, Panc-1, MiaPaCa-2, AsPC-1 and Capan-2 cells, respectively. UMI-77 induced apoptosis in pancreatic cancer through activation of the intrinsic apoptotic pathway and/or Bax conformational change. 
|In vivo||In a BxPC-3 xenograft mouse model, UMI-77 (60 mg/kg i.v.) exhibits single-agent antitumor activity without any damage normal tissues. |
Fluorescence polarization (FP)-based binding assays:Based on the Kd values, the concentrations of the proteins used in the competitive binding experiments are 90 nM for Mcl-1, 40 nM for Bcl-w, 50 nM for Bcl-xL, 60 nM for Bcl-2, and 4 nM for A1/Bfl-1. The fluorescent probes, Flu-BID and FAM-BID are fixed at 2 nM for all assays except for A1/Bfl-1 where FAMBID is used at 1 nM. 5 μL of the tested compound in DMSO and 120 μL of protein/probe complex in the assay buffer (100 mM potassium phosphate, pH 7.5; 100 μg/ml bovine gamma globulin; 0.02% sodium azide) are added to assay plates (Microfluor 2Black), incubated at room temperature for 3 h and the polarization values (mP) are measured at an excitation wavelength at 485 nm and an emission wavelength at 530 nm using the plate reader Synergy H1Hybrid. IC50 values are determined by nonlinear regression fitting of the competition curves.

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.
