Product Description
INDY is a potent, ATP-competitive inhibitor of Dyrk1A and Dyrk1B with IC50 of 0.24 μM and 0.23 μM, respectively. INDY binds in the ATP pocket of the enzyme and has Ki of 0.18 μM for Dyrk1A. INDY greatly reduces the self-renewal capacity of normal and tumorigenic cells in primary glioblastoma (GBM) cell lines and neural progenitor cells.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
At 3 μM and 30 μM, INDY (0.3-30 μM; 20 hours) virtually totally blocks tau phosphorylation [1]. Nuclear factor of activated T cells, or NFAT, signaling is blocked when acid-(Y)-phosphorylation regulator 1A is overexpressed [1].
ln Vivo
ProINDY (2.5 μM) significantly restores synchronized normal development in Xenopus laevis [1].
Cell Assay
Western Blot Analysis[1]
Cell Types: COS7 cells transfected with EGFP-Dyrk1A and EGFP-tau
Tested Concentrations: 0.3, 1, 3, 10, 30 μM
Incubation Duration: 20 hrs (hours)
Experimental Results: Mild inhibition of tau phosphorylation at 3 μM , almost complete inhibition at 30 μM.

Solubility Data
Solubility (In Vitro)
DMSO : ≥ 33.33 mg/mL (~141.65 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (10.62 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 4.2499 mL 21.2495 mL 42.4989 mL
5 mM 0.8500 mL 4.2499 mL 8.4998 mL
10 mM 0.4250 mL 2.1249 mL 4.2499 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
g/mol

Molecular Weight Calculator allows you to calculate the molar mass and elemental composition of a compound, as detailed below:

Note: Chemical formula is case sensitive: C12H18N3O4  c12h18n3o4
Instructions to calculate molar mass (molecular weight) of a chemical compound:
  • To calculate molar mass of a chemical compound, please enter the chemical/molecular formula and click the “Calculate’ button.
Definitions of molecular mass, molecular weight, molar mass and molar weight:
  • Molecular mass (or 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.

Reconstitution Calculator allows you to calculate the volume of solvent required to reconstitute your vial.

  • Enter the mass of the reagent and the desired reconstitution concentration as well as the correct units
  • Click the “Calculate” button
  • The answer appears in the Volume (to add to vial) box

Working concentration mg/mL;

Method for preparing DMSO stock solution mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.

(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
             (2) Be sure to add the solvent(s) in order.

Biological Data
  • GBM primary cells were incubated in the presence of (A) harmine or (B) INDY, and 3 days later, the spheres were dissociated and replated in the absence of the drug. A 20-μm concentration was chosen based on SVZ-NSC behavior (Figure 5A and Supplemental Figure 7). The number of secondary spheres is represented in the graphs. (C) 50,000 GBM5 cells were implanted intracranially into nude mice. Two weeks later, the animals started to receive i.p. injections of saline (Control) or harmine (15 mg/kg/day, 5 days per week; indicated by an arrow). Animal survival was evaluated using a Kaplan-Meier survival curve, and the differences in survival times were analyzed with a log-rank test (n = 5; P = 0.09). (D) Number of mitotic cells in control or harmine-treated tumor tissue. (E) Representative images of activated caspase 3 staining in control and harmine-treated tumor tissue. (F) Representative images of EGFR staining in control and harmine-treated tumor tissue. (G) Correlation between the amount of membrane EGFR present in the different GBM-TIC lines and the percentage of self-renewal inhibition induced by harmine. (H) Percentage of self-renewal inhibition induced by harmine in low- or high-passage GBM3 cells. Western blot on the right shows the amount of EGFR and DYRK1A expressed by low- and high-passage GBM3 cells. Scale bar: 40 μm. *P ≤ 0.05; **P ≤ 0.01; ***P ≤ 0.001.[2].
