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.

Ionotropic glutamate receptors (iGluRs) mediate fast excitatory neurotransmission. Upon glutamate application, 2-amino-3-(3-hydroxy-5-methyl-4-isoxazolyl)propionic acid receptors undergo rapid and almost complete desensitization that can be attenuated by positive allosteric modulators. The molecular mechanism of positive allosteric modulation has been elucidated previously by

Ionotropic glutamate receptors (iGluRs) are glutamate-gated ion channels that mediate excitatory neurotransmission in the central nervous system. Based on both molecular and pharmacological criteria, iGluRs have been divided into two major classes, the non-NMDA class, which includes both AMPA and

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
