Cholinesterase (ChE) Agonist

Aclatonium napadisylate is a cholinergic agonist. Aclatonium napadisylate can increase amylase release and Ca²⁺ efflux. Aclatonium napadisylate can stimulate pancreatic exocrine secretion and increase motility and peristalsis of the gastrointestinal tract. Aclatonium napadisylate can be used for the research of gastrointestinal disorders.

GSK1034702 hydrochloride is an orally active and allosteric agonist of M1 mAChR (pEC₅₀=8.1) that can cross the blood-brain barrier. GSK1034702 hydrochloride activates the Gq/11 protein-mediated signaling pathway, enhancing neuronal firing and long-term potentiation (LTP) in the CA1 region of the hippocampus. GSK1034702 hydrochloride can modulate hippocampal function, improve memory encoding in the nicotine withdrawal cognitive dysfunction model, and show pro-cognitive effects in rodents. GSK1034702 hydrochloride can be used for the study of the mechanisms of cognitive impairment diseases such as Alzheimer's disease, and has certain peripheral M receptor activation-related side effects (such as gastrointestinal reactions).

Bis-Q is an acetylcholine (ACh) agonist that targets voltage-clamped muscle fibers of the fish Xenomystus nigris. Bis-Q exists in two forms: cis-Bis-Q (non-agonist) and trans-Bis-Q (agonist). Photoisomerization converts cis-Bis-Q to trans-Bis-Q, which induces agonist-induced currents. Channels activated by trans-Bis-Q and ACh have similar conductances and open times. Flashes increase the ratio of trans-Bis-Q to cis-Bis-Q until light equilibrium is reached. Further flashes transiently increase agonist-induced currents, indicating binding of trans-Bis-Q to desensitized receptors. Higher concentrations of cis-Bis-Q produce larger agonist-induced currents that decay exponentially..

WAY-361789 (SEN15924) is an orally active agonist for α7 nicotinic acetylcholine receptor (α7 nAChR) with an EC₅₀ of 0.18 μM. WAY-361789 improves the cognitive function, exhibits potential in ameliorating Alzheimer’s Disease and schizophrenia.

Itameline (RU 47213) is a prodrug with oral and long-lasting cholinergic activity. Itameline is a novel tetrahydropyridine-oxime that is cleaved in vivo to form an active metabolite, RU 35963. RU 35963 is a muscarinic receptor agonist that is nonselective with respect to receptor subtypes. Itameline possesses the capacity to reduce memory deficits induced by an impairment of cholinergic transmission in the rat.
