Description

Galanthaminone (Narwedin) is a competitive and reversible cholinesterase (AChE) inhibitor; is used for the treatment of mild to moderate Alzheimer's disease and various other memory impairments.

IC50 & Target

AChE
In Vitro

Galanthaminone reduces the action of AChE and therefore tends to increase the concentration of acetylcholine in the brain. is also an allosteric ligand at nicotinic acetylcholine receptors. It has shown activity in modulating the nicotinic cholinergic receptors on cholinergic neurons to increase acetylcholine release.

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo

Absorption of Galanthaminone is rapid and complete and shows linear pharmacokinetics. It is well absorbed with absolute oral bioavailability between 80 and 100%. It has a half-life of seven hours. Peak effect of inhibiting acetylcholinesterase was achieved about one hour after a single oral dose of 8 mg in some healthy volunteers.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
