Brassinin is primarily recognized for its role in plant defense mechanisms, particularly in cruciferous vegetables like cabbage and broccoli. It functions as a phytoalexin, a compound produced by plants to combat pathogens such as fungi and bacteria. This makes it a key component in studying plant resistance to diseases and developing strategies for crop protection. Additionally, brassinin has garnered interest in the field of cancer research due to its potential anticancer properties. Studies suggest it may inhibit the growth of certain cancer cells, making it a candidate for further exploration in cancer therapy and chemoprevention. Its dual role in agriculture and medicine highlights its versatility and significance in scientific research.
