Trifolirhizin is primarily recognized for its role in plant defense mechanisms, where it acts as a phytoalexin, a compound produced by plants in response to pathogen attack. It is particularly effective against fungal infections, helping to protect the plant from diseases. In research, trifolirhizin is studied for its potential pharmacological properties, including its anti-inflammatory and anticancer activities. Its ability to modulate cellular pathways makes it a subject of interest in the development of new therapeutic agents. Additionally, trifolirhizin is used in biochemical studies to understand plant-pathogen interactions and the molecular basis of plant immunity.
