Background:

Donecopride is a partial agonist of the serotonin (5-HT) receptor subtype 5-HT_4E(K_i= 8.5 nM) and an inhibitor of acetylcholinesterase (AChE; IC₅₀= 16 nM).¹It is selective for AChE over butyrylcholinesterase (BChE; IC₅₀= 3,530 nM) but does bind to 5-HT_2Band sigma-2 (σ₂) receptors (K_i= 1.6 nM for both) in a panel of 42 neurotransmitter receptors and transporters. Donecopride induces release of soluble amyloid precursor protein-α (sAPP-α) in COS-7 cells transiently expressing 5-HT₄with an EC₅₀value of 11.3 nM. Oral administration of donecopride (1 mg/kg) reduces brain soluble and insoluble amyloid-β (1-42) levels and increases the time spent exploring the novel object in the novel object recognition (NOR) test in the 5XFAD transgenic mouse model of Alzheimer's disease. Donecopride (3 mg/kg, p.o.) prevents a reduction in spontaneous alternation behavior induced by intracerebroventricular administration of soluble Aβ42 (sAβ42) in the Y-maze in mice.²
