3-Isomangostin 可从莽吉柿壳中提取的一种天然产物，是一种乙酰胆碱酯酶选择性抑制剂，也是一种有效的人醛糖还原酶抑制剂，IC50 为 3.48 uM。它抑制 MutT 同源物 1 (MTH1)，IC50 为 52 nM。它具有清除自由基、抗疟原虫和抗癌的活性。

3-Isomangostin is an acetylcholinesterase selective inhibitor and a potent human aldose reductase inhibitor with an IC50 of 3.48 uM. 3-Isomangostin has free radical scavenging activity and inhibits MutT homolog 1 (MTH1) with an IC50 of 52 nM. It shows antiplasmodial activity with an IC50 values in the range of 4.71-11.40 uM. 3-Isomangostin can be used to develop anticancer agents as well.

Species of Garcinia have been used to combat malaria in traditional African and Asian medicines, including Ayurveda. In the current study, we have identified antiplasmodial benzophenone and xanthone compounds from edible Garcinia species by testing for in vitro inhibitory activity against Plasmodium falciparum. Whole fruits of Garcinia xanthochymus, G. mangostana, G. spicata, and G. livingstonei were extracted and tested for antiplasmodial activity. Garcinia xanthochymus was subjected to bioactivity-guided fractionation to identify active partitions. Purified benzophenones (1-9) and xanthones (10-18) were then screened in the plasmodial lactate dehydrogenase assay and tested for cytotoxicity against mammalian (Vero) cells. The benzophenones guttiferone E (4), isoxanthochymol (5), and guttiferone H (6), isolated from G. xanthochymus, and the xanthones α-mangostin (15), β-mangostin (16), and 3-Isomangostin (17), known from G. mangostana, showed antiplasmodial activity with an IC50 values in the range of 4.71-11.40 μM. Artemisinin and chloroquine were used as positive controls and exhibited an IC50 values in the range of 0.01-0.24 μM.
