    Ferulic acid ameliorates neurodegeneration via the Nrf2/ARE signalling pathway: A Review

    Background: Ferulic acid is a polyphenolic phytoconstituent synthesized from the metabolism of amino acids phenylalanine and tyrosine found in fruits and vegetables. Neurodegenerative disorders have been a thorn in the flesh of neuroscientists owing in part to the increase in the aged population. Several drugs used in the management of these disorders are either ineffective or come with unbearable side effects. We present a review of ferulic acid focusing on leveraging its antioxidant property in an attempt to explain its role in neurodegenerative disorders. Basic procedure: data were obtained by perusing scientific databases including Web of Science and PubMed. It was realised that 18,000 articles were associated with ferulic acid from 1960-to 2022. We narrowed it down using the keywords neuroprotection, and antioxidant of which we had 239 articles. Main findings: results indicated that ferulic acid has wide neuropharmacological applications due to its antioxidant, anti-inflammatory, neuroprotective and antiapoptotic effects among others. The neuroprotective effect of ferulic acid has been studied in many diseases like Alzheimer's, Epilepsy, and Parkinson's disease. Principal conclusion: the neuroprotective potential of FA may be due to its ability to absorb active forms of oxygen and nitrogen and use redox-bearing compounds to regulate genetic expression including, encoding for antioxidant enzymes, the anti-apoptotic protein family Bcl-2, and pro-survival neurotrophic factors like BDNF. Its higher bioavailability and lipophilic nature make it a better drug candidate than other polyphenols for neurological disorders. � 2022 The Author(s)

    Berberine Ameliorate Haloperidol and 3-Nitropropionic Acid-Induced Neurotoxicity in Rats
    (Springer, 2022-07-25T00:00:00) Kadir, Abdul; Singh, Jasdeep; Rahi, Vikrant; Kumar, Puneet
    Berberine due to its antioxidant properties, has been used around the globe significantly to treat several brain disorders. Also, oxidative stress is a pathological hallmark in neurodegenerative diseases like Huntington�s disease (HD) and Tardive dyskinesia (TD). Berberine an alkaloid from plants has been reported to have neuroprotective potential in several animal models of neurodegenerative diseases. Hence, this study aims to evaluate the neuroprotective effect of berberine in the animal model of 3-nitropropionic acid (3-NP) induced HD and haloperidol induced tardive dyskinesia with special emphasis on its antioxidant property. The study protocol was divided into 2 phases, first phase involved the administration of 3-NP and berberine at the dose of (25, 50, and 100�mg/kg) intraperitoneally (i.p) and orally (p.o.) respectively for 21�days, and the following parameters (rotarod, narrow beam walk and photoactometer) as a measure of motor activity and striatal and cortical levels of (LPO, GSH, SOD, catalase, and nitrate) evaluated as a measure of oxidative stress were assessed for HD. Similarly in the second phase, TD was induced by using haloperidol, for 21�days and berberine at the dose of (25, 50, and 100�mg/kg) was administered, and both physical and biochemical parameters were assessed as mentioned for the HD study. The resultant�data indicated that berberine attenuate 3-NP and haloperidol-induced behavioral changes and improved the antioxidant capcity in rodents. Hence berberine might be a novel therapeutic candidate to manage TD & HD. � 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
