Zanapezil (TAK-147) is a potent, reversible and selective acetylcholine esterase (AChE) inhibitor. Zanapezil shows a potent and reversible inhibition of AChE activity in homogenates of the rat cerebral cortex (IC50=51.2 nM). Zanapezil shows a moderate inhibition of muscarinic M1 and M2 receptor binding with Ki values of 234 and 340 nM, respectively. Zanapezil can be used for the research of early stages of Alzheimer's disease (AD)[1][2]. | [Definition]
ChEBI: Zanapezil fumarate is a polymer. | [in vivo]
Oral administration of Zanapezil (TAK-147; 3 mg/kg) significantly accelerated the turnover rates of dopamine, noradrenaline and serotonin in the rat brain. Oral administration of Zanapezil at doses ranging from 1 to 10 mg/kg induces a statistically significant and dose-dependent decrease in AChE activity in the cerebral cortex in ex vivo experiments[1].
Zanapezil (TAK-147; 5 and 10 mg/kg) significantly increases ACh level in the ventral hippocampus (VH) for 120 min[2]. | [IC 50]
