To investigate the effects of flavonoids on free radical-mediated biological membrane damage and the interaction of flavonoids with heme proteins, we studied the effects of quercetin, its glycosides (rutin and quercetin-3-O-glucoside), morin and (-)epicatechin on the hemolysis of the bovine erythrocytes induced by the hydrophilic free radical initiator, 2,2'-azobis(2-amidinopropane)dihydrochlor...

Combinations of selected phytochemicals (reserpine, pyrrolidine, quinine, morin and quercetin) with antibiotics (ciprofloxacin, tetracycline and erythromycin) were tested on the prevention and control of Staphylococcus aureus biofilms. The phytochemicals were also studied for their ability to avoid antibiotic adaptation and to inhibit antibiotic efflux pumps. Morin, pyrrolidine and quercetin at...

The effects of six flavonoids viz., apigenin, genistein, morin, naringin, pelargonidin and quercetin on the susceptibility of low-density lipoprotein (LDL) to oxidative modification were investigated. Flavonoids were added to plasma and incubated for 3 hr at 37 degrees C, and the LDL fraction was separated by ultracentrifugation. Oxidizability of LDL was estimated by measuring conjugated diene ...

Brain ischemia induces neuronal loss which is caused in part by excitotoxicity and free radical formation. Here, we report that mangiferin and morin, two antioxidant polyphenols, are neuroprotective in both in vitro and in vivo models of ischemia. Cell death caused by glutamate in neuronal cultures was decreased in the presence of submicromolar concentrations of mangiferin or morin which in tur...

The antibacterial activities of flavoneids vvere found by the paper disk method to be enhanced by combini"g or mixi'ng them. The combinEtions of quercetin and quercitrin, quercetin and mori", and quercetin and rutin were much more actiye than either flayonoid alone. Altheugh rutin did not show activity in itse}f, the antibacterial activities of quercetin and morin were enhanced in the presence ...

Several oxovanadium(V) complexes have been shown as a potent anticancer agents. In view of the importance of Vanadium complexes a new Vanadium – Morin complex was synthesized and comprehensively characterized. To provide an insight on the mode and affinity of the interaction of these complex with calf thymus (CT) DNA the following experiments were carried out: fluorescence spectroscopy, UV–vis ...

Cadmium (Cd) a toxic heavy metal environmental pollutant imposes deleterious health consequences to human population. Reports suggest that rampant free radical generation and oxidative stress are the cardinal event in Cd induced neurotoxicity. Recently, therapeutic intervention using bioflavonoids gaining more attention to mitigate oxidative stress related pathologies. Thus the present study wa...

Hyperuricemia is associated with a number of pathological conditions such as gout. Lowering of elevated uric acid level in the blood could be achieved by xanthine oxidase inhibitors and inhibitors of renal urate reabsorption. Some natural compounds isolated from herbs used in traditional Chinese medicine have been previously demonstrated to possess xanthine oxidase inhibitory activities. In the...
