hAChE-IN-2 is a dual-action small molecule exhibiting potent inhibition of human acetylcholinesterase (IC50 = 0.71 µM) and suppression of tau oligomerization (EC50 = 2.21 µM). This neuroprotective profile makes it a valuable research tool for in vitro and in vivo studies in Alzheimers disease and related tauopathy research.
