应用

Methyllycaconitine citrate salt has been used as an α7 nicotinic acetylcholine receptor (α7 nAChR) antagonist:
  • to study its effects on inflammatory response in rats post nicotine treatment
  • to block the activity of galantamine
  • to study its effects on the hepatic branch of the vagus nerve (hVNS) in rats

生化/生理作用

Methyllycaconitine (MLA) is an α7 nicotinic acetylcholine receptor (α7 nAChR) antagonist. It is a norditerpenoid alkaloid synthesized by several species of Delphinium. MLA binds to the binding site of neuronal α-bungarotoxin. Low doses of MLA are associated with improvement of cognition in animals.

The brain needs mechanisms able to correlate plastic changes with local circuit activity and internal functional states. At the cerebellum input stage, uncontrolled induction of long-term potentiation or depression (LTP or LTD) between mossy fibres and granule cells can saturate

Plants have evolved effective strategies to defend themselves against pathogen invasion. Starting from the plasma membrane with the recognition of microbe-associated molecular patterns (MAMPs) via pattern recognition receptors, internal cellular signaling pathways are induced to ultimately fend off the attack.

The hippocampus is a brain region that is rich in nicotinic acetylcholine receptors (nAChRs), especially the α7 subtype. The hippocampus is severely affected in disorders that have a neuroinflammatory component, such as Alzheimer's disease, Parkinson's disease, and schizophrenia. Previous studies

Stimuli associated with nicotine can become motivationally significant and may play a role in tobacco dependence. Previous work indicates that nicotine enhances responding for a conditioned reinforcer (CR). These studies examined the effects of prior exposure to nicotine on responding
