In Alzheimer's disease (AD) basal forebrain cholinergic neurons appear to be targeted primarily in early stages of the disease. Scopolamine (muscarinic receptor antagonist) has been used for decades to induce working and reference memory impairment in rodents. In this study, we evaluated the protective effect of kolaviron, a biflavonoid complex isolated from Garcinia kola seeds extract against scopolamine-induced memory impairment/oxidative stress. Rats were pretreated with kolaviron (25, 50 or 100 mg/kg p...

Vitamin E forms are substantially metabolized to various carboxychromanols including 13'-carboxychromanols (13'-COOHs) that are found at high levels in feces. However, there is limited knowledge about functions of these metabolites. Here we studied δT-13'-COOH and δTE-13'-COOH, which are metabolites of δ-tocopherol and δ-tocotrienol, respectively. δTE-13'-COOH is also a natural constituent of a traditional medicine Garcinia Kola. Both 13'-COOHs are much stronger than tocopherols in inhibition of pro-inflammatory and cancer promoting cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX), and in induction of apoptosis and autophagy in colon cancer cells...

Influenza A viruses (IAV) induce cytokine storm and host's intracellular redox imbalance to ensure continuous replication and survival, leading to severe immunopathology and death. The unpredictability of broad-spectrum vaccines, the emergence of drug-resistant and/or more virulent strains, the prevalence of the amantadane-resistant IAV, and the prohibitive cost of available drugs especially in resource-poor countries necessitate exploring drugs with novel action mechanisms as anti-influenza agents. This study presents the protective role of kolaviron (KV), a natural antioxidant and anti-inflammatory agent from Garcinia kola seeds, on BALB/c mice challenged with influenza A/Perth/H3N2/16/09 (Pr/H3N2) virus...

The pathophysiology of stroke is characterized by biochemical and physical alterations in the brain. Modulation of such aberrations by therapeutic agents affords insights into their mechanism of action. Incontrovertible evidences that oxidative stress is involved in the pathophysiology of neurologic disorders have brought antioxidative compounds, especially plant phytochemicals, under increasing focus as potential remedies for the prevention and management of neurodegenerative diseases. Kolaviron, a biflavonoid complex isolated from Garcinia kola Heckel (Guttiferae) was evaluated for neuroprotectivity in brains of male Wistar rats submitted to bilateral common carotid artery occlusion-induced global ischemia/reperfusion injury (I/R)...
