Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Biosynthesis of a Flavonol from a Flavanone by Establishing a One-pot Bienzymatic Cascade

Published on: August 14, 2019

Main Results:

  • Isolation of one new dihydrochalcone (compound 4) and four known compounds: dammaradienol (1), (-)-5-methoxyflavan-7-ol (2), 5-methoxy-6-methyl-2-phenyl-7H-chromen-7-one (3), and dracorhodin (5).
  • Compounds 1, 2, and 3 exhibited notable cytotoxicity against both KB and HepG2 cells.
  • The structures of all isolated compounds were confirmed through comprehensive spectral analysis.

Conclusions:

  • Draconis Resina contains a diverse array of bioactive compounds, including novel chalcones.
  • Compounds 1, 2, and 3 show promising cytotoxic effects, warranting further investigation for anticancer drug development.
  • This study contributes to the understanding of Draconis Resina's chemical composition and therapeutic potential.
