IDRA-21 (7-chloro-3-methyl-3,4-dihydro-2H-1,2,4-benzothiadiazine 1,1-dioxide) reduces alpha-amino-3-hydroxy-5-methylisoxazolepropionic acid (AMPA) receptors desensitisation in vitro and restores learning and cognitive impairment in vivo. In this study, we show that in cerebellar granule cells (CGCs) in culture IDRA-21 reduces N-methyl-d-aspartate receptor (NMDAR) whole-cell currents. The

The direct analytical and semipreparative high-performance liquid chromatographic (HPLC) resolution of the enantiomers of IDRA 21 [1,7-chloro-3-methyl-3,4-dihydro-2H-1,2,4-benzothiadiazine S,S-dioxide] is reported. (+/-)-IDRA 21 administered orally to rats subjected to a water maze cognition test elicited a performance enhancing effect. Between the
