Formula

C18H14BrNO5S2
Molecular Weight 468.34 CAS No. 518303-20-3
Solubility (25°C)* In vitro DMSO 93 mg/mL (198.57 mM)
Ethanol 93 mg/mL (198.57 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 30%PEG300 ddH2O
6.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 120 mg/ml clarified DMSO stock solution to 300 μL of PEG 300, mix evenly to clarify it; then continue to add 650 μL of ddH2O to adjust the volume to 1 mL. 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 UMI-77 is a selective Mcl-1 inhibitor with Ki of 490 nM, showing selectivity over other members of Bcl-2 family.
Targets
Mcl-1 [1]
(Cell-free assay)
490 nM(Ki)
In vitro UMI-77 effectively disrupts the interactions between BL-Noxa and cellular Mcl-1, as well as Mcl-1/Bax protein–protein interactions. [1] 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. [1]
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. [1]

Protocol (from reference)

Kinase Assay:

[1]
  • 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.

Cell Assay:

[1]
  • Cell lines

    Human pancreatic cancer cell lines AsPC-1, BxPC-3, Panc-1, MiaPaCa and Capan-2

  • Concentrations

    ~100 μM

  • Incubation Time

    4 days

  • Method

    Human pancreatic cancer cell lines AsPC-1, BxPC-3, and Capan-2 are cultured in RPMI-1640 medium, whereas Panc-1 and MiaPaCa are cultured in Dulbeccos' Modified Eagle's Medium (DMEM), all supplemented with 10% FBS. The cell growth inhibition after treatment with increasing concentrations of the compounds is determined by WST-8 assay.
Animal Study:

[1]
  • Animal Models

    ICR-SCID mice bearing BxPC-3 tumor xenograft

  • Dosages

    ~60 mg/kg daily

  • Administration

    i.v.
