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.
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:


  • 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 Research:


  • 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 Research:


  • Animal Models: ICR-SCID mice bearing BxPC-3 tumor xenograft
  • Dosages: ~60 mg/kg daily
  • Administration: i.v.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
