The potential role of mangiferin in cancer treatment through its immunomodulatory, anti-angiogenic, apoptopic, and gene regulatory effects.

Mangiferin (1,3,6,7-tetrahydroxyxanthone-C2-β-D-glucoside) is a natural bioactive xanthonoid that can be found in many plant species, among which the mango tree (Mangifera indica L), a plant widely used in the traditional medicinal, is one of its primary sources. The use of mangiferin for cancer treatment has attracted the attention of research groups around the World. Single administration of mangiferin or in combination with known anticancer chemicals has shown the potential benefits of this molecule in lung, brain, breast, cervix, and prostate cancers, and leukemia.

Mango polyphenols and its protective effects on diseases associated to oxidative stress.

Biological effects of natural polyphenols from mango and their potential impact on human health have become of increasing interest. The occurrence of glycosilated molecules, such as mangiferin (C2-β-D-glucopyranosyl-1,3,6,7-tetrahydroxyxanthone), main component of the mango polyphenolic fraction, and benzophenones, flavonoids (catechin and epicatechin), phenolic acids (benzoic and gallic), and a wide range of derivatives, provide a high chemical complexity. In this review, the potential impact of mango polyphenols and its protective effects on diseases associated to oxidative stress is discussed.

The paradox of natural products as pharmaceuticals. Experimental evidences of a mango stem bark extract.

Recent findings regarding basic, pre-clinical and clinical studies on a mango stem bark extract (MSBE) developed in Cuba (Vimang) on an industrial scale are summarized. Ethnomedical studies, extract reproducibility, biological effects and clinical evaluations in terms of patient quality of life are described as experimental evidences to support the statement that natural products, even being a mixture of compounds, could be as effective as "monoceuticals" for medical uses. Discussion about the use of "monoceuticals" versus "natureceuticals" in health care and medicine is based on effectiveness and availability, taking Vimang as an example of a natural product with supported scientific evidence to be used as antioxidant, analgesic, anti-inflammatory and immunomodulator.

Comparison of major and trace element concentrations in 16 varieties of Cuban mango stem bark (Mangifera indica L.).

An aqueous decoction of mango (Mangifera indica L.) stem bark (MSB) has been developed in Cuba on an industrial scale to be used as a nutritional supplement, cosmetic, and phytomedicine, with antioxidant, anti-inflammatory, analgesic, and immunomodulatory properties. The concentration of major and trace elements was determined for 16 varieties of MSB belonging to two cultivars and grown in Cuba in the same soil (red ferralytic).

Mangifera indica L. extract (Vimang) inhibits 2-deoxyribose damage induced by Fe (III) plus ascorbate.

Vimang is an aqueous extract of selected species of Mangifera indica L, used in Cuba as a nutritional antioxidant supplement. Many in vitro and in vivo models of oxidative stress have been used to elucidate the antioxidant mechanisms of this extract. To further characterize the mechanism of Vimang action, its effect on the degradation of 2-deoxyribose induced by Fe (III)-EDTA plus ascorbate or plus hypoxanthine/xanthine oxidase was studied.

Dual mechanism of mangiferin protection against iron-induced damage to 2-deoxyribose and ascorbate oxidation.

We studied mangiferin effects on the degradation of 2-deoxyribose induced by Fe(III)-EDTA/citrate plus ascorbate, in relation to ascorbate oxidation (measured at 265 nm). Results revealed that mangiferin was equally effective in preventing degradation of both 15 and 1.5 mM 2-deoxyribose.

Mangifera indica L. (Vimang) protection against serum oxidative stress in elderly humans.

Background: We searched for the protective effect of a natural extract from stem bark of Mangifera indica L. extract (Vimang) on age-related oxidative stress.

Methods: Healthy subjects were classified in two groups, elderly (>65 years) and young group (<26 years).

Protection against septic shock and suppression of tumor necrosis factor alpha and nitric oxide production on macrophages and microglia by a standard aqueous extract of Mangifera indica L. (VIMANG). Role of mangiferin isolated from the extract.

The present study illustrates the effects of a standard aqueous extract, used in Cuba under the brand name of VIMANG, from the stem bark of Mangifera indica L. on the production of tumor necrosis factor alpha (TNFalpha) and nitric oxide (NO) in in vivo and in vitro experiments. In vivo was determined by the action of the extract and its purified glucosylxanthone (mangiferin) on TNFalpha in a murine model of endotoxic shock using Balb/c mice pre-treated with lipopolysaccharide (LPS) 0.

In vivo and in vitro anti-inflammatory activity of Mangifera indica L. extract (VIMANG).

A standard aqueous extract of Mangifera indica L., used in Cuba as an antioxidant under the brand name of VIMANG, was tested in vivo for its anti-inflammatory activity using commonly accepted assays. M.

Protective effect of Mangifera indica L. extract (Vimang) on the injury associated with hepatic ischaemia reperfusion.

The effect of Mangifera indica L. extract (Vimang) on treatment of injury associated with hepatic ischaemia/reperfusion was tested. Vimang protects from the oxidative damage induced by oxygen-based free radicals as shown in several in vitro test systems conducted.

Isolation and quantitative analysis of phenolic antioxidants, free sugars, and polyols from mango (Mangifera indica L.) stem bark aqueous decoction used in Cuba as a nutritional supplement.

An aqueous decoction of mango (Mangifera indica L.) stem bark has been developed in Cuba on an industrial scale to be used as a nutritional supplement, cosmetic, and phytomedicine. Previously we reported its antioxidant activity, and we concluded that the product could be useful to prevent the production of reactive oxygen species and oxidative tissue damage in vivo.
