AD-35 free base
AD-35 free base is an orally active, blood-brain barrier-permeable acetylcholinesterase inhibitor with an IC50 of 793 nM. AD-35 free base inhibits metal-induced amyloid-β aggregation and disassembles preformed amyloid-β aggregates. In rat models of cognitive impairment, AD-35 free base attenuates Aβ25-35-induced astrocyte activation, TNF-α and IL-1β release, inhibits ERK phosphorylation, and alleviates learning and memory deficits. AD-35 free base can be used for research on Alzheimer's disease.

AD-35 (pre-incubated for 10 min, incubated with substrate for 15 min) free base moderately inhibits purified acetylcholinesterase (IC50 = 793 nM) and butyrylcholinesterase (IC50 = 31428 nM) in vitro, and exhibits activity preference for acetylcholinesterase[1].
AD-35 (20 μM; 10 min) free base effectively chelates Cu2+ and Fe3+ in vitro, but exhibits extremely weak chelating activity towards Zn2+[1].
AD-35 (6-10 μM; 5 h) free base weakly promotes Cu2+ transport into human neuroblastoma SH-SY5Y cells in vitro[1].
AD-35 (24 h) free base potently inhibits Cu2+-induced Aβ1-42 aggregation in a concentration-dependent manner in vitro, exerts only weak inhibitory effects on the spontaneous aggregation of Aβ1-42, and effectively disassembles preformed Cu2+-induced Aβ1-42 aggregates[1].

Animal Model:Sprague-Dawley (SD) (male, 8-10 weeks old, 260-280 g, intracerebroventricular injection of aggregated Aβ25-35 peptide)[1]
-
Dosage:0.5 mg/kg; 3 mg/kg; 10 mg/kg
-
Administration:p.o.; daily; 28 days
-
Result:Prolonged step-down latency and decreased error times dose-dependently in Aβ25-35-injected rats, with complete reversal of Aβ-induced deficits at 10 mg/kg.
Shortened escape latency during 5-day training.
Improved spatial memory in probe trials: 0.5 mg/kg group spent 28.7% of time in target quadrant, 3 mg/kg group spent 38.2%, 10 mg/kg group spent 29.7%, all exceeding 25% chance level.
Normalized time spent in target quadrant (22.91 s) and escape latency to platform (15.43 s) at 3 mg/kg relative to sham controls.
Reduced Aβ-induced TNF-α overexpression in the hippocampus dose-dependently, with significant reduction at 10 mg/kg.
Markedly inhibited Aβ-induced IL-1β overexpression in the hippocampus at all tested doses.
Suppressed Aβ-induced GFAP expression in the cortex and hippocampus.
Inhibited Aβ-induced ERK phosphorylation in the hippocampus dose-dependently.
