General description

Pentylenetetrazole (PTZ) is a tetrazole derivative and inhibitor of the γ aminobutyric acid (GABAA) and its receptor complex. PTZ is a convulsing agent used for inducing seizures. It can traverse the blood-brain barrier.

Application

Pentylenetetrazole has been used to induce seizures in zebra fish larvae, mice, and male wistar rats.

Biochem/physiol Actions

Pentylenetetrazole is a non-specific central nervous system (CNS) stimulant and convulsant. PTZ induces oxidative stress and increases cortical malondialdehyde content and affects hippocampus, resulting in seizures.

Zebrafish have recently emerged as an attractive in vivo model for epilepsy. Seven-day-old zebrafish larvae exposed to the GABA(A) antagonist pentylenetetrazol (PTZ) exhibit increased locomotor activity, seizure-like behavior, and epileptiform electrographic activity. A previous study showed that 12 out of
