gartanin/neoplasms

Garcinia mangostana, often referred to as mangosteen, is a fruit grown in Southeast Asia and has been used for centuries as a local beverage and natural medicine. Its bioactive compounds, xanthones (i.e., gartanin, α-mangostin, etc), have reported effects on ailments ranging from skin infections and

A screening study using a luciferase assay to identify natural products that enhance death receptor 5 (DR5) expression was carried out, and bioassay-guided fractionation of two organisms, the pericarp of Garcinia mangostana (mangosteen) and actinomycete CKK609 strain, led to the isolation of eight

Our current interest in searching for natural anti-cancer lead compounds from plants has led us to the discovery that the stem and roots of Garcinia mangostana can be a source of such compounds. The stem furnished 2,8-dihydroxy-6-methoxy-5-(3-methylbut-2-enyl)-xanthone (1), which is a new xanthone.

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related death worldwide. Development of novel agents to eradicate liver cancer cells is required for treatment of HCC. Gartanin, a xanthone-type compound isolated from mangosteen, is known to possess potent antioxidant,

Androgen receptor (AR) has been a target of prostate cancer for nearly seven decades. In the last several years there has been an interest in identifying compounds that promote degradation of the androgen receptor. In the present study, gartanin, an isoprentylated xanthone in the mangosteen fruit,

Gartanin, a 4-prenylated xanthone, has been identified from the purple mangosteen fruit as a potent growth inhibitor of various cancer cell lines, including prostate cancer. However, much of Gartanin's anticancer mechanism remains unknown. We have discovered that Gartanin docked onto the regulatory

In central nervous system, glioma is the most common primary brain tumour. The diffuse migration and rapid proliferation are main obstacles for successful treatment. Gartanin, a natural xanthone of mangosteen, suppressed proliferation, migration and colony formation in a time- and

Three new prenylated xanthones, mangostenones C (1), D (2), and E (3), together with 16 known xanthones 4-19, were isolated from the young fruit (7-week maturity stage) of Garcinia mangostana. The structural elucidation of the new compounds was mainly established on the basis of 1D and 2D NMR and

Bioassay-guided fractionation of an ethanol extract of the pericarps of Garcinia mangostana led to the isolation of two new prenylated xanthones, named 1,3,7-trihydroxy-2-(3-methyl-2-butenyl)-8-(3-hydroxy-3-methylbutyl)-xanthone (1) and

Garcinia mangostana L. (the queen of fruits, mangosteen, family Guttiferae) is a wealthy source of xanthones. The CHCl3 soluble fraction of the air-dried pericarps of G. mangostana provided a new xanthone: mangostanaxanthone VII (5), along with four known xanthones: mangostanaxanthones I (1) and II

Uncontrolled regulation of cyclin dependent kinases (CDKs) has negative implications in many cancers and malignancies and has recently led to the approval of select CDK inhibitors. Herein we present data reporting that xanthones, a class of compounds isolated from the purple mangosteen (Garcinia
