DL-Pyroglutamic acid (CAE) as an inactivator of hepatitis B surface, inactivates vaccinia virus, herpes simplex virus, and influenza virus except poliovirus. DL-Pyroglutamic acid is also a possible inhibitor of GABA transaminase, increases GABA amount with antiepileptic action[1][2].

In Vitro	DL-Pyroglutamic acid results 50 and 100% inactivation of the antigen of 0.01-0.025% and 0.025-0.05%, respectively[1]. DL-Pyroglutamic acid is a possible glutamate antagonist, blocks glutamate miniature-end-plate potential in locust muscle-Druce and Bradford[2].
In Vivo	DL-Pyroglutamic acid (0.775 mM/L) completely abolishes the myoclonic jerks and EEG spikes in rats model of epileptic by cobalt implantation in the sensorimotor cerebral cortex[2].
