Cancer Prevention

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.

Two novel flavonoids, castilliferol and castillicetin, were isolated from Centella asiatica. Both compounds demonstrated significant antioxidant activity, highlighting their potential therapeutic benefits.

Area of Science:

Phytochemistry
Natural Products Chemistry
Pharmacognosy

Background:

Centella asiatica, a medicinal herb, is a rich source of bioactive compounds.
Investigating the chemical constituents of Centella asiatica can lead to the discovery of novel therapeutic agents.

Discussion:

Two new flavonoids, castilliferol (1) and castillicetin (2), were identified alongside isochlorogenic acid (3).
The isolation process involved comprehensive spectroscopic analysis, including 1D and 2D NMR.
The structural elucidation confirmed the novelty of compounds 1 and 2.

Key Insights:

Castilliferol and castillicetin exhibit potent antioxidant properties.
The 2,2-diphenyl-1-picryl hydrazyl radical scavenging assay revealed IC(50) values of 23.10 for castilliferol and 13.30 for castillicetin.
