Scientists have made a breakthrough in the fight against fat and inflammation by developing new compounds derived from menthol. Menthol, a natural cyclic monoterpene alcohol found in plants like peppermint and spearmint, is known for its medicinal properties including analgesic, anti-inflammatory, and anti-cancer effects.

In a recent study led by Professor Gen-ichiro Arimura from Tokyo University of Science, researchers created menthyl esters of valine (MV) and isoleucine (MI) by modifying menthol’s structure. These derivatives showed superior anti-inflammatory properties compared to menthol in cell line studies and experiments on mice.

The research, published in the Immunology journal, highlighted the potential of these compounds in combating inflammation. The team synthesized menthyl esters of six amino acids with less-reactive side chains and found that MV and MI effectively suppressed genes involved in inflammatory and immune responses.

Professor Arimura expressed his motivation for the study, stating, ‘Discovering new molecules from natural materials has always been a focus for our research team. The development of these amino acid derivatives of menthol opens up exciting possibilities in the field of medicinal chemistry.’

The researchers also investigated the mechanism of action of the menthyl esters and identified the liver X receptor (LXR) as a key player in their anti-inflammatory effects. This discovery sheds light on the potential therapeutic applications of these compounds in treating inflammatory conditions.

This groundbreaking research showcases the power of natural product derivatives in addressing health challenges and paves the way for future advancements in drug development and treatment strategies.
