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]

Protocol (from reference)

Cell Research: [4]
  • 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.
Animal Research:[2]
  • Animal Models: Mice infected with L. major
  • Dosages: 5 mg/kg/day
  • Administration: i.p. or p.o.

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

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
