Biological Activity

Description Licochalcone A is an estrogenic flavanoid extracted from licorice root, showing antimalarial, anticancer, antibacterial and antiviral activities. Phase 3.
In vitro

Licochalcone A markedly inhibits the in vitro growth of L. major amastigotes in human MDMs and U937 cells. [1] Licochalcone A shows antibacterial effects against all gram-positive bacteria tested and especially against all Bacillus spp. Tested with MICs of 2 to 3 micrograms/mL. [3] In CT-26 colon cancer cells, Licochalcone A reduces the cell viability and DNA synthesis. [4] Licochalcone A also interferes with MAPK signaling cascades, initiates ROS generation, induces oxidative stress and consequently causes BGC cell apoptosis. [5]

In vivo In mice infected with L. major, licochalcone A (5 mg/kg, i.p.) completely prevents lesion development. In mice infected with L. donovani, licochalcone A (150 mg/kg, p.o.) results in > 65 and 85% reductions of parasite loads in the liver and the spleen, respectively. [2] In CT-26 cell-inoculated Balb/c mice, licochalcone A (1 mg/kg, p.o.) inhibits the tumor growth, and alleviates cisplatin-induced nephrotoxicity and hepatotoxicity. [4]


Cell Research: [4]
- Collapse
  • Cell lines: CT-26 cells
  • Concentrations: ~20 μM
  • Incubation Time: 72 hours
  • Method: The viability of CT-26 mouse colon cancer cells is determined via a MTT assay. In brief, colon cancer cells are seeded onto each well of a 96-well plate with DMEM containing 10% FBS and cultured to adhere overnight. The cells are then treated with various concentrations of LCA in serum-free medium for 24 and 72 hr, respectively. Twenty microlitres of a MTT solution (5 mg/ml) is added to each well, and the cells are incubated for 4 hr at 37°. The medium is then removed, and 200 µL of dimethyl sulfoxide is added to each well. The absorbance is determined at 570 nm using a microplate reader.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (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.
