產(chǎn)品描述：

Targeting α7 neuronal acetylcholine receptors (nAChRs) with selective agonists and positive allosteric modulators (PAMs) is considered a therapeutic approach for managing cognitive deficits in schizophrenia and Alzheimer's disease. A-867744 is a novel type II PAM with good potency and selectivity.

In vitro: In oocytes expressing α7 nAChRs, A-867744 potentiated acetylcholine (ACh)-evoked currents, with an EC50 value of about 1 μM. At highest concentrations of A-867744 tested, ACh-evoked currents were essentially nondecaying. At lower concentrations, no evidence of a distinct secondary component was evident in contrast to 4-naphthalen-1-yl-3a,4,5,9b-tetrahydro -3H-cyclopent-a[c]quinoline-8-sulfonic acid amide (TQS), another type II α7 PAM [1].

In vivo: A-867744 was assessed for its PK properties in rat, dog, and monkey. The animal pharmacokinetic profile of A-867744 was characterized by relatively low plasma clearance values (1.1-2.5 L/h/kg) and volumes of distribution (1.7-4.6 L/kg) across species, with terminal elimination halflives in the 1.0-1.7 h. The bioavailability is 83% in rat and somewhat lower in dog (55%) and monkey (68%). These findings indicated that A-867744 showed acceptable pharmacokinetic profile across species and brain levels sufficient to modulate α7 nAChRs [2].

Clinical trial: A-867744 is currently in the preclinical developlent stage and no clinical data are available.
