• 产品描述： PNU-120596 (NSC 216666) is a potent and selective α7 nAChR positive allosteric modulator (PMA) with an EC50 of 216 nM. PNU-120596 is inactive against α4β2, α3β4, and α9α10 nAChRs. PNU-120596 has the potential for psychiatric and neurological disorders research

• 靶点： EC50: 216 nM (α7 nAChR);AChR

• 体外研究：
  PNU-120596 increases agonist-evoked calcium flux mediated by an engineered variant of the human α7 nAChR. Electrophysiology studies confirme that PNU-120596 increases peak agonist-evoked currents mediated by wild-type receptors and also demonstrates a pronounced prolongation of the evoked response in the continued presence of agonist. PNU-120596 increases the channel mean open time of α7 nAChRs.
  When applied to acute hippocampal slices, PNU-120596 increases the frequency of ACh-evoked GABAergic postsynaptic currents measured in pyramidal neurons.
  PNU-120596 enhances agonist-evoked gating of nicotinic receptors by eliciting conformational effects that are similar but nonidentical to the gating conformations promoted by ACh.

• 体内研究：
  PNU-120596 (1 mg/kg; intravenous injection; once) treatment improves the auditory gating deficit caused by Amphetamine in rats, a model proposed to reflect a circuit level disturbance associated with schizophrenia.
  When administered before carrageenan, NU-120596 (30 mg/kg; i.p.) significantly reduces mechanical hyperalgesia and weight-bearing deficits for up to 4 h in Sprague-Dawley rats. PNU-120596 attenuates the carrageenan-induced increase in levels of TNF-α and IL-6 within the hind paw oedema Animal Model: Male Sprague Dawley rats (250-300 g) treated with Amphetamine Dosage: 1 mg/kg Administration: Intravenous injection; once Result: Improved the auditory gating deficit caused by Amphetamine.
