BuChE-IN-11 (Compound 3b-1) is an selective BuChE inhibitor with an IC 50 of 0.44 μM for hBuChE. BuChE-IN-11 has high blood-brain barrier permeability and exhibits strong antioxidant activity due to its free radical scavenging properties. BuChE-IN-11 interacts with the choline binding site, acetyl binding site, and peripheral anionic site, exhibiting submicromolar BuChE inhibitory activity and preventing β-amyloid (Aβ) self-aggregation. BuChE-IN-11 holds promise for research in the field of Alzheimer's disease.
