isogarcinol/garcinia

Isogarcinol is a new immunosuppressant that we extracted from Garcinia mangostana L. In the present study, we elucidate its beneficial effect in chronic graft-versus-host disease (cGVHD) in mice -- a model for systemic lupus erythematosus (SLE) in human. The oral administration of 60 mg/kg

Isogarcinol, a bioactive polyisoprenylated benzophenone derivative isolated from Garcinia mangostana L., has been shown previously to exert a strong inhibitory effect on calcineurin and is thus a potential oral, low-toxicity immunomodulatory drug. In the present study, enzyme kinetic analysis showed

Isogarcinol is a natural compound that we extracted from Garcinia mangostana L., and we were the first to report that it is a new immunosuppressant. In the present study, we investigated the immune regulation and anti-inflammatory effects of isogarcinol on collagen-induced arthritis (CIA) and

Isogarcinol is a new natural immunosuppressant that was extracted from Garcinia mangostana L. in our laboratory. Knowledge of its effects on treatable diseases and its mechanism of action is still very limited. In this study, we explored the therapeutic effect of isogarcinol in experimental

Isogarcinol (YDIS), a natural compound extracted from Garcinia mangostana L., has a significant immunosuppressive effect on systemic lupus erythematosus and rheumatoid arthritis. This paper reports that it reduced imiquimod-induced psoriasis-like skin lesions in mice. It strongly attenuated the

BACKGROUND Plants from garcinia genus have been used for centuries against several diseases. OBJECTIVE This study aimed to investigate the mechanism of apoptosis induced by epigarcinol and isogarcinol isolated from the root of Garcinia ovalifolia (Clusiaceae) on human promyelocytic leukemia (HL-60

Calcineurin (CN), a unique protein phosphatase, plays an important role in immune regulation. In this study we used CN as a target enzyme to investigate the immunosuppressive properties of a series of natural compounds from Garcinia mangostana L., and discovered an active compound, isogarcinol.

This paper describes a method that includes an optimized extraction process and identification and quantification of two anticancer compounds (garcinol and isogarcinol) by LC/electrospray ionization (ESI)-MS/MS in the multiple reaction monitoring (MRM) mode. The study aimed to develop a fast,

An aqueous ethanolic extract of the stem bark of Garcinia buchananii showed strong antioxidative activity using H2O2 scavenging, oxygen radical absorbance capacity (ORAC), and Trolox equivalent antioxidant capacity (TEAC) assays. Activity-guided fractionation afforded three new compounds,

A new xanthone, mboudiexanthone (1), together with five known compounds, euxanthone (2), isogarcinol (3), garcinol (4), betulinic acid (5) and zeorin (6) were isolated from the leaves of Garcinia nobilis Engl. The structures were determined by 1D and

From the methanol extract of the twigs and leaves of Garcinia bancana MIQ., one new biphenyl derivative (1), was isolated and characterized along with nine known compounds; garcinol, isogarcinol, (-)-mellein, 8-hydroxy-6-methoxy-3-n-pentylisocoumarin, blumenol C O-beta-D-glucoside, quercetin

Benzophenone derivatives, garcinol (1) and isogarcinol (2) isolated from the pericarps of Garcinia purpurea (Guttiferae), and xanthochymol (3) and a mixture of isoxanthochymol (4) cycloxanthochymol (5) from the pericarps of G. subelliptica were evaluated for their antibacterial activity against

We examined the in vitro effects of the benzophenone derivatives garcinol, isogarcinol, and xanthochymol on cell growth in four human leukemia cell lines. All of the compounds exhibited significant growth suppression due to apoptosis mediated by the activation of caspase-3. A loss of mitochondrial

In a further study on the chemical constituents of Garcinia assigu, two new benzophenones corresponding to the 13-O-methyl ethers (1 and 2) of the known isogarcinol and garcinol, respectively, were isolated and characterized, along with known benzophenones (3-6). Inhibitory effects of the
