Area of Science:

  • Medicinal Chemistry
  • Pharmacology
  • Cancer Research

Background:

  • Licochalcone A from licorice exhibits anti-inflammatory and anti-tumorigenic properties.
  • Chalcones are a class of compounds with potential therapeutic applications.

Purpose of the Study:

  • To synthesize and evaluate novel chalcone derivatives for anti-tumorigenic activity.
  • To identify structure-activity relationships of chalcone derivatives in cancer inhibition.

Main Methods:

  • In vitro screening using tetradecanoylphorbol-13-acetate (TPA)-induced phospholipid phosphorylation inhibition in HeLa cells.
  • In vivo testing on mouse skin tumors initiated by dimethylbenz[a]-anthracene (DMBA) and promoted by TPA.
  • Assessment of proliferation inhibition in human gastric cancer (HGC-27) cells.

Main Results:

  • Over 40 chalcone derivatives were synthesized and tested.
  • 3 - and 4 -methyl-3-hydroxychalcone demonstrated the highest anti-tumorigenic potency.
  • These compounds significantly inhibited HGC-27 cell proliferation.

Conclusions:

  • 3 - and 4 -methyl-3-hydroxychalcone are promising anti-cancer agents.
  • Structure-activity relationships and phototransformation of chalcones were investigated using UV and NMR spectroscopy.
