Description：alpha-Mangostin (α-Mangostin) is a dietary xanthone with broad biological activities, such as antioxidant, anti-allergic, antiviral, antibacterial, anti-inflammatory and anticancer effects. It is an inhibitor of mutant IDH1 (IDH1-R132H) with a Ki of 2.85 μM.

In Vitro：alpha-Mangostin (α-Mangostin) exhibits a selective inhibitory effect on IDH1-R132H, but not on IDH1. alpha-Mangostin (α-Mangostin) competitively inhibits the binding of alpha-mangostin (α-KG) to IDH1-R132H. The structure–relationship study reveals that alpha-Mangostin (α-Mangostin) exhibits the strongest core inhibitor structure. alpha-Mangostin (α-Mangostin) selectively promotes demethylation of 5-methylcytosine (5mC) and histone H3 trimethylated lysine residues in IDH1 (+/R132H) MCF10A cells[1]. Cell proliferation significantly decreases in a dose-dependent manner in the cells treated with alpha-mangostin. Alpha-mangostin also increases the levels of Bax (pro-apoptotic), cleaved caspase-3, cleaved caspase-9 and cleaved-poly(ADP-ribose) polymerase (PARP)[2]. alpha-Mangostin (α-Mangostin) significantly inhibits light-induced degeneration of photoreceptors and 200 μM H2O2-induced apoptosis of RPE cells. 200 μM H2O2-induced generation of reactive oxygen species (ROS) and light-induced generation of malondialdehyde (MDA) are suppressed by alpha-Mangostin (α-Mangostin)[3].

In Vivo：alpha-Mangostin (α-Mangostin) reduces risk of liver fibrosis through the decrease in p53 expression as compared to the TAA_DMSO treatment. The serum levels of the liver enzymes AST and ALT after treatment with α-mangostin decrease as compared to DMSO alone[4].

Animal Administration：Rats: Male Wistar rats are divided into 3 groups and treated with intraperitoneal injections of TAA (200 mg/kg). One subgroup is left untreated whereas the other two are treated either with 100 mg/kg alpha-mangostin or vehicle alone (80% DMSO, 20% water), which are administered intraperitoneally 3 times per weekfor a total of4 weeks. The incidence offibrotic nodules on the liver and the serum levels of the liver enzymes aspartate transaminase (AST) and alanine transaminase (ALT) are measured[4].

Cell Assay：IDH1+/+ and IDH1 MCF10A cells are grown in DMEM/F-12 media, supplemented with 5% horse serum, 20 ng/mL EGF, 0.5 μg/mL hydrocortisone, 10 μg/mL insulin. IDH1+/+ and IDH1 MCF10A cells are seeded in 6 well plates. After an exposure to 5 μM alpha-mangostin. cells are collected after indicated times and the viable cell number is calculated, using hemacytometer counting[1].
