(-)-DHMEQ is primarily used in research to study its potential anti-inflammatory and anti-cancer properties. It works by inhibiting the activation of NF-kappaB, a protein complex involved in cellular responses to stress, cytokines, and infections. By blocking NF-kappaB, (-)-DHMEQ helps reduce inflammation and may suppress tumor growth. This makes it a valuable tool in understanding the mechanisms of inflammatory diseases and cancer. Researchers are exploring its potential therapeutic applications, particularly in conditions where NF-kappaB plays a key role, such as rheumatoid arthritis, inflammatory bowel disease, and certain types of cancer.
