Biochem/physiol Actions

Neuroprotective agent
OBA-09 is a neuroprotective agent. It is an ester of pyruvate and salicylic acid that acts as a multi-functional agent to protect against ischemic damages to the brain. Administration of 5 mpk OBA-09 following middle cerebral artery occlusion (MCAO) or oxygen-glucose deprivation (OGD) models of ischemic injury in rats prevents lipid peroxidation, ROS production and causes the recovery of NAD and ATP concentrations to near basal levels. The compound leads to reduction of infarct volume and also accelerates the recovery of behavioral and neurological deficits.
