In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
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 of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of 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
0.41mg/ml Taking the 1 mL working solution as an example, add 50 μL of 8.2 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 MK571 is a selective, orally active CysLT1 receptor(Cysteinyl leukotriene receptor) antagonist.
Targets
CysLT1 [1] MRP1 [2] MRP4 [2] cMOAT [4]
In vitro

L-660,711 inhibited [3H]LTD4 binding in guinea pig lung with a Ki value of 0.22±0.15 nM (n=35) and [3H]LTD4 binding in human lung with a Ki value of 2.1±1.8 nM (n=29). L660,711 was essentially inactive versus [3H]LTC4 binding with IC50 values of 23±11 μM (n=16) and 32 μM (n=1) in guinea pig and human lung, respectively[1].
In vivo

MK-571 is well tolerated in healthy young men. After oral administration, MK-571 is rapidly absorbed. The maximum plasma concentration occurring at 1.1-1.5 h at all doses[3].

Protocol (from reference)

Cell Assay:

[2]
  • Cell lines

    Glioblastoma cell lines(U251, MZ-256, and MZ-327)

  • Concentrations

    25 µM

  • Incubation Time

    7 h

  • Method

    Cells were seeded onto 96 well plates at a concentration of 1×103 cells per well and incubated for 72 h at 37℃ and 5% CO2 to allow MRP1 messenger RNA suppression to occur. Cells were then treated with either control media or one of three chemotherapy drugs. Cells were then returned to the incubator for a further 72 h; after which time, Metylthiazol Tetrazolium (MTT) powder in PBS (50µl of 5 mg/ml) was added to each well. Cells were then incubated for a further 4 h after which all solution was removed and DMSO was added. After 10 min incubation time at 37◦C, absorbance was recorded at 570 nm wavelength and data was recorded and analyzed. Small molecule inhibitors MK571 (25 µM) and Reversan (15µM) were added 7 h prior to carrying out further drug treatment or assay assessment (media change for proliferation and 2D-migration assays)
Animal Study:

[1]
  • Animal Models

    Male Msueley strain guinea pigs

  • Dosages

    0.001-3.0 mg/kg

  • Administration

    i.v.
