Ceratotoxin A is primarily recognized for its role in biological research, particularly in studies involving insect physiology and toxicology. It is used to investigate the effects of natural toxins on insect nervous systems, providing insights into potential mechanisms for pest control. Researchers utilize this compound to explore its interaction with ion channels and cellular receptors in insects, which can lead to the development of novel insecticides. Additionally, it serves as a tool in understanding the broader ecological impacts of natural toxins and their potential applications in agriculture and environmental management.
