Coluracetam
Based on 3 publication(s) in Google Scholar
Coluracetam (MKC-231) is an orally taken choline uptake enhancer. Coluracetam can improve the reduced acetylcholine levels in the hippocampus of rats and mice, enhancing learning difficulties, memory deficits, and cognitive impairments. Coluracetam induces a lower degree of hepatic venous hyperglycemia.

Biological Activity
Coluracetam (1-3 mg/kg, oral, once a day for 8 days) improves cognitive and learning impairments in rats[2].
Coluracetam (5×10-8 and 5×10-7 mol, ventricular injection, single dose) slightly increases hepatic venous glucose levels[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
