Nootropic agents or cognitive enhancers are purported to improve mental functions such as cognition, memory, or attention. The aim of our study was to determine the effects of two possible cognitive enhancers, huperzine A and IDRA 21, in normal young

We report here on the ability of IDRA 21 and aniracetam, two negative allosteric modulators of glutamate-induced DL-alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor desensitization, to attenuate alprazolam-induced learning deficit in patas monkeys working in a complex behavioral task. In one component of

Using appropriate internal standards, quantitative reverse transcripase-polymerase chain reaction (RT-PCR), and cerebellar granule cell (CG) in primary cultures we have quantified the expression of mRNAs encoding for GluR1-4 DL-alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA) receptor subunits during neuronal maturation in vitro. GluR1 is

IDRA 21, a positive allosteric modulator of the glutamate AMPA receptor, produced a concentration-dependent inhibition of glutamate-induced inactivation of membrane currents in recombinant HEK 293 (human embryonic kidney) cells stably transfected with human GluR1/2 flip receptors. IDRA 21 doubled the

In cerebellar granule neurons of neonatal rats micromolar concentrations of 7-chloro-3-methyl-3,4-dihydro-2H-1,2, 4-benzothiadiazine S,S-dioxide (IDRA-21) and cyclothiazide, two negative modulators of the spontaneous agonist-dependent rapid desensitization of alpha-amino-3-hydroxy-5-methylisoxazolepropionic acid (AMPA)-gated ion channels, facilitate AMPA receptor function by increasing the content of
