Description | 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]. |
