The transcription factor, STAT3, is associated with proliferation, survival, and metastasis of cancer cells. We investigated whether gambogic acid (GA), a xanthone derived from the resin of traditional Chinese medicine, Garcinia hanburyi (mangosteen), can regulate the STAT3 pathway, leading to
Protein tyrosine phosphatase 1B (PTP1B) plays important role in diabetes, obesity and cancer. The methanol extract of the gum resin of Garcinia hanburyi (G. hanburyi) showed potent PTP1B inhibition at 10µg/ml. The active compounds were identified as prenylated caged xanthones (1-9) which inhibited
In the search for natural hypoglycaemic agents as alternatives to synthetic ones that are expensive and not easily accessible, and to justify the use of Garcinia kola seeds in traditional African medicine to treat diabetes, the hypoglycaemic and hypolipidaemic effects of fractions from kolaviron
BACKGROUND
Garcinia spp. belongs to the family Clusiaceae has been traditionally used for the treatment of many ailments including the liver damage. Garcinia dulcis found in North Eastern region of Assam; India can be a potential candidature to combat different ailments. Objective: The present work
Garcinia pedunculata Roxb. is an important medicinal plant of North Eastern (NE) region of India, having number of medicinal properties and used against various diseases in folk medicine. An empirical research was designed to carry out evaluation of hepatoprotective activity of the leaves of
The hepatoprotective effect of a biflavonoid complex, kolaviron, and its fractions from Garcinia kola seeds, together with the possible mechanisms involved was investigated in mice intoxicated with a single dose of D-galactosamine (GalNH(2)). Likewise, the ability of vitamin E to attenuate the
This study was undertaken to investigate the toxicological profile of a methanolic extract of Garcinia pedunculata fruit in rats by conducting hematological, biochemical, and histopathological examinations. Long Evans rats were divided into four groups, each with 6 animals, and were treated with
The role of oxidative stress in the pathogenesis of alcoholic diseases in the liver is well documented. Kolaviron (KV), a biflavonoid complex from Garcinia kola seeds, possesses a variety of biological activities, including antioxidant. Our aim was to investigate in vivo whether KV may attenuate
This study investigated the ameliorative effects of kolaviron (a biflavonoid from the seed of Garcinia kola) and vitamin C on ethylene glycol monoethyl ether (EGEE)-induced oxidative damage in boar spermatozoa in vitro. EGEE (1.0 mm) was incubated with boar spermatozoa for 3 h with or without either
Phenytoin, an anticonvulsant agent used for the treatment of epilepsy has been reported to exhibit toxic side effects on the liver and testes. The present study investigated the protective effects of kolaviron (KV, a bioflavonoid from Garcinia kola seeds) against hepatic and testicular damage in
The present work examines the protective mechanisms of a biflavonoid fraction of an extract from Garcinia kola seeds, kolaviron, in rats treated with carbontetrachloride (CCl(4)). CCl(4)administered at a dose of 1.2 g kg(-1), three times a week for 2 weeks, significantly depressed the activities of
In this study, we examined the modulatory effects of kolaviron, a biflavonoid from Garcinia kola seeds on the antioxidant defense mechanisms, cellular redox status and oxidative stress in the kidney and liver of rats pretreated with potassium bromate (KBrO(3)) intragastrically as a single dose of
BACKGROUND
Mistletoe extracts (decoctions) are used traditionally in eastern Nigeria for the management of bone pain, post menopausal syndrome and diabetes amongst several other ailments. While scientific evidence supporting its folkloric use as an antidiabetic agent has been documented, the
The effect of kolaviron, a mixture of Garcinia biflavonoid 1 (GB1), Garcinia biflavonoid 2 (GB2) and kolaflavanone, used in the treatment of various ailments in southern Nigeria on hepatotoxicity and lipid peroxidation induced by 2-acetylaminofluorene (2-AAF) in rats was investigated. The ability of
BACKGROUND
The aim of this study was to evaluate the cardioprotective effects of kolaviron (KV), a biflavonoid from Garcinia kola seeds, in rats intoxicated with isoproterenol chloride (ISO) while quercetin (QUE) served as standard.
METHODS
Forty-two male Wistar rats (180-200 g) were randomly
