hAChE-IN-1 (Compound 24) is a dual-action small molecule that potently inhibits human acetylcholinesterase (IC50 = 1.09 µM) and reduces tau oligomerization (EC50 = 2.71 µM) in cellular FRET assays. This profile supports its research use in investigating Alzheimers disease mechanisms and evaluating potential therapeutic strategies in both biochemical and cellular models.
