Dehydroandrographolide is primarily used in pharmaceutical and medicinal applications due to its potent biological activities. It exhibits strong anti-inflammatory and antiviral properties, making it valuable in the development of treatments for respiratory infections, including the common cold and flu. It is also studied for its potential in modulating immune responses, which can be beneficial in autoimmune conditions and chronic inflammatory diseases. Research suggests it may have anticancer effects by inducing apoptosis in certain tumor cells, particularly in liver and breast cancer models. Additionally, it has been explored for hepatoprotective applications, helping protect the liver from damage caused by toxins or infections. Its ability to inhibit key inflammatory pathways, such as NF-κB, contributes to its broad therapeutic potential in both traditional and modern medicine systems.
