Description
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/17898229 | http://adisinsight.springer.com/drugs/800020139

A-582941 was found to exhibit high-affinity binding and agonism at alpha-7 nicotinic acetylcholine receptor (α7-nAChR), with acceptable pharmacokinetic properties and excellent distribution to the central nervous system. In vitro and in vivo studies indicated that A-582941 activates signaling pathways known to be involved in cognitive function such as ERK1/2 and CREB phosphorylation. A-582941 enhanced cognitive performance in behavioral assays including the monkey delayed matching-to-sample, rat social recognition, and mouse inhibitory avoidance models that capture domains of working memory, short-term recognition memory, and long-term memory consolidation, respectively. AbbVie is developing α7-nAChR agonists including A-582941 as neuroprotective agents for the treatment of cognitive disorders such as Alzheimer's disease and schizophrenia. Development is at the preclinical stage.

CNS Activity

Curator's Comment: A-582941 is CNS penetrant and active in animals. No human data available.

Sample Use Guides

Administration of A-582941 (1 μmol/kg, i.p.) in mouse produced maximal levels in brain (286 ng/g at 0.33 h) that were 11-fold higher than the plasma C max (26 ng/ml at 0.25 h). This distribution ratio was maintained over an 8 h period, as drug cleared from brain and plasma with t 1/2 = 2.5–3.2 h. Similarly, in rat, A-582941 partitions with approximate sixfold higher levels in brain versus plasma after intraperitoneal dosing at 2–20 μmol/kg. Over this dose range, linear pharmacokinetics was observed, with brain C max (normalized to a 1 μmol/kg dose) averaging 363 ng/g and maximum plasma levels of 62 ng/ml.
Route of Administration: Intraperitoneal
