Heteroclitin B is a plant-derived alkaloid used in biochemical research for its acetylcholinesterase (AChE) inhibitory activity, which affects the nervous system and is studied for both neurotoxic models and neuroprotective potential. It shows promise in Alzheimer's disease and other neurodegenerative disorders by modulating neurotransmitter systems, such as enhancing cholinergic activity to support cognitive function. Its ability to effectively cross the blood-brain barrier makes it a candidate for central nervous system drug development. Additionally, it is investigated for anti-inflammatory effects in neural tissues and for antidote development against toxicity.
