产品描述

PNU-282987 is a selective α7 nicotinic acetylcholine receptor(α7 nAChR) agonist with Ki of 26 nM; no affinity for α1β1γδ and α3β4 nAChRs (IC50 ≥ 60 μM).IC50 value: 26 nM(Ki) [1]Target: α7 nAChR agonistin vitro: Treatment with PNU-282987 resulted in an attenuation of neuroinflammation in the MPTP-lesioned SN. Furthermore, PNU-282987 attenuated MPTP-induced dopaminergic cell loss in the SN and reduced striatal dopamine depletion [3].in vivo: Mice were subjected to 70% partial hepatic I/R for 60 min and pretreated with either vehicle or with PNU-282987, and blood and hepatic tissue samples were collected at 3, 6, and 12 h following reperfusion. pretreatment with PNU-282987 decreased serum transaminase levels and ameliorated liver injury after hepatic I/R. Moreover, pretreatment with PNU-282987 suppressed NF-κB activation, cytokine production (tumor necrosis factor α, interleukin 1β), and HMGB1 expression in liver after hepatic I/R [2]. Mice treated with 2.5 and 10 mg/kg of PNU devoted less time to rearing into open arms. In the HB task, MC mice displayed higher exploratory activity reflected in more head-dips (HD) during the first minute than EE and SE, whereas EE displayed low exploration levels reflected in total HD (5 min) [4].
