Zanapezil (TAK-147) is a selective reversible acetylcholine (ACh) esterase inhibitor that was designed as a drug for Alzheimer's disease (AD) treatment. The development of the drug was discontinued due to a lack of a dose-dependent effect in the trials.

Sample Use Guides

In Vivo Use Guide

Daily oral administration of TAK-147 (1 mg/kg) for 40 days increased phosphocreatine and ATP levels in brains of aged Fischer rats.

Route of Administration: Oral

In Vitro Use Guide

The inhibitory potency of TAK-147 towards AChE activity (IC50) was found to be 51.2 nM in vitro. AChE activities were measured using the radioisotopic method on male Wistar rats' cerebral cortices.
