General description

Cyclothiazide is a benzothiadiazine, which has a similar structure to diazoxide.

Application

Cyclothiazide has been used as a α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) desensitization blocker to study the effects of γ2 on receptor desensitization.

Biochem/physiol Actions

Blocks the rapid desensitization of the AMPA glutamate receptors and markedly prolongs the decay time of the evoked excitatory post-synaptic current.

We have investigated the role of AMPA receptor desensitization during transmission at a calyceal synapse. Cyclothiazide blocked the rapid desensitization of AMPA receptors and markedly prolonged the decay time of the evoked excitatory postsynaptic current (PSC). This effect was greater

In whole-cell recordings from mammalian CNS neurons, AMPA-preferring glutamate receptors exhibit strong desensitization in response to AMPA, glutamate, and quisqualate, but not to kainate or domoate. Such desensitization is reduced by lectins, by the nootropic drug aniracetam, and by diazoxide.

During development of the calyx of Held synapse, presynaptic action potentials (APs) become substantially faster and briefer. Nevertheless, this synapse is able to upregulate quantal output triggered by arriving APs. Briefer APs lead to less effective gating of voltage-gated Ca(2+)

AMPA receptors are ligand-gated ion channels that show multiple conductance levels, indicating that gating of individual AMPA subunits is to some extent independent of the other subunits. To study AMPAR subunit interactions during activation gating, we recorded from single channels

Hypothalamic hypocretin/orexin (hcrt/orx) neurons promote arousal and reward seeking, while reduction in their activity has been linked to narcolepsy, obesity and depression. However, the mechanisms influencing the activity of hcrt/orx networks in situ are not fully understood. Here we show
