MedKoo CAT#: 526847

CAS#: 123464-89-1 (HCl)

Description: PNU282987 is a drug that acts as a potent and selective agonist for the α7 subtype of neural nicotinic acetylcholine receptors. In animal studies, it shows nootropic effects, and derivatives may be useful in the treatment of schizophrenia, although PNU-282,987 is not suitable for use in humans because of excessive inhibition of the hERG antitarget.

Product Data:
Biological target: PNU-282987 is a potent α7 nicotinic acetylcholine receptor (nAChR) agonist with an EC50 of 154 nM.
In vitro activity: In the present study, using pharmacological inhibition and genetic knockout of α7nAChR, this study assessed the antiapoptotic effects of an α7nAChR agonist PNU-282987 in primary cultured astrocytes treated with 1-methyl-4-phenylpyridinium (MPP+). PNU-282987 promoted the viability of astrocytes, alleviated MPP+ induced apoptosis, and decreased the number of GFAP+/TUNEL+ cells. Meanwhile, PNU-282987 upregulated the expression of the antiapoptotic protein Bcl-2 and downregulated the expression of the apoptotic protein Bax and cleaved-caspase-3. Moreover, the suppression of the JNK-p53-caspase-3 signaling may underlie the neuroprotective property of PNU-282987. Therefore, PNU-282987 ameliorates astroglial apoptosis induced by MPP+ through α7nAChR-JNK-p53 signaling. Reference: Front Cell Neurosci. 2019 Nov 12;13:507. https://pubmed.ncbi.nlm.nih.gov/31780901/
In vivo activity: Amphetamine-induced sensory gating deficit, determined by auditory-evoked potentials in hippocampal CA3 region, was restored by systemic administration of PNU-282987 in chloral hydrate-anesthetized rats. Auditory gating of rat reticular thalamic neurons was also disrupted by amphetamine; however, PNU-282987 normalized gating deficit only in a subset of tested neurons (6 of 11). Furthermore, PNU-282987 improved the inherent hippocampal gating deficit occurring in a subpopulation of anesthetized rats, and enhanced amphetamine-induced hippocampal oscillation. This study proposes that the alpha7 nAChR agonist PNU-282987, via modulating/enhancing hippocampal GABAergic neurotransmission, improves auditory gating and enhances hippocampal oscillatory activity.
