guttiferone a/garcinia

Benzophenones from natural sources and those of synthetic analogues present several reports of potent biological properties, and Guttiferone A represents a promising medicinal natural compound with analgesic and gastroprotective profiles. Considering that there are no reports that assess the genetic

This study was undertaken to evaluate the gastroprotective properties of seed, leaf, and branch methanolic extracts and guttiferone A obtained from Garcinia achachairu (Clusiaceae). Mice were used in all the models, and treatments were administered orally only in pylorus-ligated model of the

Previous studies indicate that extracts and purified components from Garcinia species inhibit the growth of human colon cancer cells. Garcinia benzophenones activate the expression of genes in the endoplasmic reticulum and cellular energy stress (mTOR) pathways. This study examines the growth

The constituents of the leaves of Garcinia intermedia and heartwood of Calophyllum brasiliense were investigated based on their trypanocidal activity against epimastigotes of Trypanosoma cruzi, the etiologic agent of Chagas' disease. As the active components, the polyisoprenylated benzophenone

Infections by protozoans of the genus Leishmania are the major worldwide health problem, with high endemicity in developing countries. The drugs of choice for the treatment of leishmaniasis are the pentavalent antimonials, which exert renal and cardiac toxicity. Thus, there is a strong need for

The prior study of the extraction path is fundamental to optimize the required time and to define the most suitable solvent to extract and determine an analyte of interest in a complex sample. This study aimed to evaluate four extraction modes; solvent sequence in Soxhlet equipment (SES), and

Two new polyisoprenylated benzophenones, 32-hydroxy-ent-guttiferone M (1) and 6-epi-guttiferone J (2), along with seven known compounds, 6-epi-clusianone (3), guttiferone A (4), xanthochymol (5), guttiferone E (6), isoxanthochymol (7), (+)-volkensiflavone (8), and (+)-morelloflavone (9), were

A robust, direct, rapid and non-destructive X-ray diffraction crystallography method to detect the polyprenylated benzophenones 7-epi-clusianone (1) and guttiferone A (2) in extracts from Garcinia brasiliensis is presented. Powder samples of benzophenones 1 and 2, dried hexane extracts from G.

Mastitis is an inflammation of the mammary gland that causes major losses in the dairy industry. Streptococcus spp. are among the main agents of this disease. Increased resistance to antibiotics is one of the causes of therapeutic failure. Plants, due to their broad chemodiversity, are an

BACKGROUND The stem bark of Garcinia livingstonei is used traditionally as a skin lightening agent. OBJECTIVE To isolate and identify compounds responsible for the observed skin lightening activity of Garcinia livingstonei and to evaluate their cytotoxicity. METHODS Constituents of the stem bark and

We have investigated the in vitro inhibition of papain, trypsin, and cathepsins B and G by five benzophenone-type compounds, three natural ones isolated from Garcinia brasiliensis and two synthetic derivatives. The activities of pentaprenylated trihydroxy-substituted benzophenone guttiferone A (1)

The pericarp and seeds from fruits of Garcinia brasiliensis were subjected to extraction with hexane and ethanol. The pericarp hexane extract (PHE) and seed ethanol extract (SEE) were purified by silica gel column chromatography, which permitted isolation of the prenylated benzophenones

Bioassay-guided fractionation of the EtOAc extract of the twigs of Garcinia macrophylla from Suriname produced the known benzophenone, guttiferone A (1), and a new guttiferone analogue, guttiferone G (2). Friedelin was also isolated. The structures of compounds 1 and 2 were elucidated using 1D and

A series of 13 known compounds, including seven benzophenones [guttiferone A (1), guttiferone K (2), xanthochymol (3), guttiferone E (4), cycloxanthochymol (5), isoxanthochymol (6), and gambogenone (7)], five biflavonoids [amentoflavone (8), 3,8''-biapigenin (9), (+)-volkensiflavone (10),

In a search for new and effective analgesic substances from the Brazilian biodiversity, the present study evaluates the chemical composition and antinociceptive potential of the methanol extract and a pure compound obtained from the seeds of Garcinia achachairu Rusby (Clusiaceae). The methanolic
