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

1. Patch-clamp technique was used in primary cultures of cerebellar granule neurons to study the modulation of the cyclothiazide analogue (IDRA21) and of the diazoxide derivative (IDRA 5) on KA-evoked currents. 2. The dose-response of kainic acid (KA) reveals an

The diazoxide derivative 7-chloro-3-methyl-3,4-dihydro-2H-1,2,4-benzothiadiazine-S,S-dioxide (IDRA21) enhances memory and learning in rodents, most likely by potentiating AMPAergic synaptic activity. We examined IDRA21's effect upon AMPAergic synaptic currents and whole-cell glutamate currents in cultured rat hippocampal neurons to determine whether IDRA21 was

Positive alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) modulators enhance glutamate transmission via the AMPA receptor by altering the rate of desensitization; alone they have no intrinsic activity. They are the only class of compounds known that may pharmacologically separate AMPA subtypes. This manuscript

IDRA 21 (7-chloro-3-methyl-3,4-dihydro-2H-1,2,4-benzothiadiazine S,S-dioxide) has been reported to modulate AMPA receptor kinetics and to improve memory in certain animal models. In the present study, its effects on synaptic transmission and long-term potentiation (LTP) were tested in hippocampal slices. IDRA 21
