Biological Activity

Description MG-101 (ALLN, Calpain inhibitor-1, Ac-LLnL-CHO) is a cell-permeable and potent inhibitor of cysteine proteases including calpains and lysosomal cathepsins.
Targets
Cysteine protease [1]
In vitro MG-101 (ALLN) effectively inhibits cysteine proteinases with ID50 of 7 nM and 13 nM for cathepsins L and B, respectively. MG-101 (ALLN) shows very weak inhibitory activities towards cathepsin D (aspartic protease) and subtilisin (serine protease). MG-101 thus transforms NIH3T3 cells and also induces differentiation of PC12 pheochromocytoma cells. [1] MG-101, as an inhibitor of Ca(2+)-dependent cysteine proteases, inhibits the degradation of HMG-CoA reductase and HMGal in cholesterol biosynthesis. [2] In HCT116 cells, MG-101 decreases cell viability and tumor growth, and induces apoptosis response through Bax translocation from cytosol to mitochondria. [3]
In vivo In mice bearing HCT116 xenografts, MG-101 (10 mg/kg i.p.) inhibits colon tumor formation. [3]

Protocol (from reference)

Cell Assay:[3]
  • Cell lines

    HCT116, HCT116/p53−/−, and HCT116/Bax−/− cells

  • Concentrations

    ~26 μM

  • Incubation Time

    24 hours

  • Method

    Cells viability is assayed using Cell Counting Kit-8 following manufacturer’s protocol. All HCT116 cell typesare seeded into each well of 96-well plate, cultured to 80% density and treated with different doses of ALLN for 24 h. Medium is then replaced by 100 μl fresh McCoy’s 5A complete medium with 10% CCK-8 reagent and incubated for 1 h. Absorbance is measured at 450 nm using a microplate reader. Results are shown as death percentages.
Animal Study: [3]
  • Animal Models

    Female athymic nude mice bearing HCT116 xenografts

  • Dosages

    10 mg/kg

  • Administration

    i.p.
