Daphnicyclidin D is primarily studied for its potential neuroprotective and cognitive-enhancing properties. It has shown activity in modulating neurotransmitter systems, particularly those involving acetylcholine and glutamate, making it a candidate for research in neurodegenerative disorders such as Alzheimer's disease. Its ability to cross the blood-brain barrier efficiently enhances its potential as a lead compound in developing nootropic or neuroregenerative agents. Additionally, preliminary studies suggest anti-inflammatory effects in neural tissues, which may contribute to its neuroprotective profile. Due to its complex structure, it is also used as a molecular probe to study ion channel function and receptor interactions in the central nervous system.
