The opening of mitochondrial permeability transition (mPT) pore is a well recognized important event in the execution of mitochondrial-mediated apoptosis. Some bioactive compounds induce apoptosis in tumour cells via the induction of mPT pore opening. This study therefore investigated the effect of 3-Para-fluorobenzoyl-propionic acid (3PFBPA), a metabolite of haloperidol on mPT pore, mitochondrial ATPase activity (mATPase), mitochondrial lipid peroxidation (mLPO) and cytochrome c release (CCR). Thirty-two male Wistar rats, were acclimatized for 14 days in clean cages. After 30 days of treatment, they were sacrificed and the liver mitochondria isolated using differential centrifugation.

However, oral administration of 3PFBPA at 50, 100 and 200 mg/kg did not have any effect on mPT pore opening and mATPase activity when compared with the control but there was inhibition of mLPO. These findings suggested the pharmacological potential of 3PFBPA against the pathological processes related to insufficient apoptosis (based on the in vitro data) and oxidative stress due to its anti-lipidperoxidative effect.
