Product Description

Indole-3-carbinol (I3C; 3-Indolemethanol) is natural product produced by the breakdown of the glucosinolate glucobrassicin, which can be found at relatively high levels in cruciferous vegetables. NF-κB activity, an AhR agonist, and an inhibitor of WWP1 (a WW domain-containing ubiquitin E3 ligase 1) are all inhibited by it.

Biological Activity I Assay Protocols (From Reference)
Targets
NF-κB; AhR; Human Endogenous Metabolite
ln Vitro
It has been discovered that indole-3-carbinol (I3C) has low toxicity toward healthy monocytes and inhibits the proliferation of THP-1 cells in a dose- and time-dependent manner. When exposed to indole-3-carbinol, the AhR target genes CYP1A1 and IL1β are overexpressed (p<0.05 to p<0.001). Indole-3-carbinol's antiproliferative properties are linked to its ability to program cell death. In THP-1 cells, indole-3-carbinol downregulates BCL2 while upregulating FasR (p<0.05 to p<0.001). Using flow cytometry, it is also possible to see G1 cell cycle arrest. Indole-3-carbinol treatment results in overexpression of G1-acting cell cycle genes (P21, P27, and P53) (p<0.05 to p<0.001) and downregulation of CDK2 (p<0.01 to p<0.001)[1].In pre-B acute lymphoblastic leukemia cells, Indole-3-carbinol inhibits NF-κB activity while promoting the p53 pathway[2].
Cell Assay
In a fully humidified environment with 5% CO2, THP-1 cells are cultured in RPMI 1640 with 10% FBS, 100 U/mL penicillin, 100 mg/mL streptomycin, and 2 mM Glutamax. Six-well plates are seeded with cells (2-5×105 mL-1), and the cells are then resuspended in full growth medium. Then, 10 ng/mL phorbol 12-myristate 13-acetate is added to THP-1 monocyte cells as a tumor promoter to cause stable differentiation into adhering macrophage-like cells and overexpression of AhR. Following that, indole-3-carbinol (1, 10, 100μM, and 1 mM) is treated with various concentrations in the cells. In a 24-well plate with different concentrations of indole-3-carbinol, HP-1 cells and enriching normal monocytes are seeded at a density of 5 104 cells/well. After 24 and 48 hours, MTT assay is performed. Triplicates of the cells are incubated for 20 hours in a final volume of 200 mL of Phenol Red-free RPMI 1640. Each well is filled with an aliquot of 20 mL of MTT solution (5 mg/mL), which is then left to sit for 4 hours. Crystals of formazan grow. Then, as a cell lysis solution, 300 mL of DMSO is added to each well. Spectrophotometry at 570 nm is used to measure cell viability percentage[1].

  • 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
