Daun02 is primarily utilized in neuroscience research, particularly in the field of chemogenetics. It is employed as a tool to selectively inactivate neurons that have been genetically modified to express specific receptors. This chemical is often used in conjunction with Designer Receptors Exclusively Activated by Designer Drugs (DREADDs). When administered, Daun02 deactivates these engineered neurons, allowing researchers to study the functional roles of specific neural circuits in behavior, cognition, and disease models. Its application is crucial for understanding the causal relationships between neuronal activity and physiological or pathological processes, aiding in the development of targeted therapies for neurological disorders.
