The in vitro antimalarial interaction of 9-Hydroxycalabaxanthone and α-mangostin with mefloquine/artesunate
Acta Parasitol 2014 Mar;60(1):105-11.PMID:26204026DOI:10.1515/ap-2015-0013.
Multidrug resistance Plasmodium falciparum is the major health problem in Thailand. Discovery and development of new antimalarial drugs with novel modes of action is urgently required. The aim of the present study was to investigate the antimalarial interaction of 9-Hydroxycalabaxanthone and α-mangostin with the standard antimalarial drugs mefloquine and artesunate in chloroquine sensitive (3D7) and chloroquine resistant (K1) P. falciparum clones in vitro. Median (range) IC50 (drug concentration which produces 50% parasite growth inhibition) values of the 9-Hydroxycalabaxanthone, α-mangostin, artesunate and mefloquine for 3D7 vs K1 clones were 1.5 (0.9-2.1) vs 1.2 (1.1-1.6) μM, 17.9 (15.7.0-20.0) vs 9.7 (6.0-14.0) μM, 1.0 (0.4-3.0) vs 1.7 (1.0-2.5) nM, and 13.3 (11.1-13.3) vs 7.1 (6.7-12.2) nM, respectively. Analysis of isobologram and combination index (CI) of 9-Hydroxycalabaxanthone with artesunate or mefloquine showed synergistic and indifference antimalarial interaction, respectively. α-mangostin-artesunate combination exhibited a slight antagonistic effect of antimalarial interaction, whereas α-mangostin and mefloquine combination showed indifference interaction in both clones. The combination of 9-Hydroxycalabaxanthone with α-mangostin showed the synergistic antimalarial interaction in both clones.
Mangostanaxanthone VIII, a new xanthone from Garcinia mangostana and its cytotoxic activity
Nat Prod Res 2019 Jan;33(2):258-265.PMID:29513040DOI:10.1080/14786419.2018.1446012.
A new prenylated xanthone, mangostanaxanthone VIII (7) and six known metabolites: gartanin (1), 1,3,8-trihydroxy-2-(3-methyl-2-butenyl)-4-(3-hydroxy-3-methylbutanoyl)-xanthone (2), rubraxanthone (3), 1,3,6,7-tetrahydroxy-8-prenylxanthone (4), garcinone C (5), and xanthone I (9-Hydroxycalabaxanthone) (6) were separated from the EtOAc-soluble fraction of the air-dried pericarps of Garcinia mangostana (Clusiaceae). Their structures have been verified on the basis of spectroscopic data analysis as well as comparison with the literature. The cytotoxic activity of 7 was assessed against MCF7, A549, and HCT116 cell lines using sulforhodamine B (SRB) assay. Compound 7 showed significant cytotoxic potential against MCF7 and A549 cell lines with IC50s 3.01 and 1.96 μM, respectively compared to doxorubicin (0.06 and 0.44 μM, respectively). However, it exhibited moderate activity towards HCT116 cell line.
Mangostanaxanthones I and II, new xanthones from the pericarp of Garcinia mangostana
Fitoterapia 2014 Oct;98:215-21.PMID:25128900DOI:10.1016/j.fitote.2014.08.014.
Two new xanthones: mangostanaxanthones I (3) and II (5) were isolated from the pericarp of Garcinia mangostana, along with four known xanthones: 9-Hydroxycalabaxanthone (1), parvifolixanthone C (2), α-mangostin (4), and rubraxanthone (6). Their structures were elucidated on the basis of IR, UV, 1D, 2D NMR, and MS spectroscopic data, in addition to comparison with literature data. The isolated compounds were evaluated for their antioxidant, antimicrobial, and quorum-sensing inhibitory activities. Compounds 3 and 5 displayed promising antioxidant activity with IC50 12.07 and 14.12 μM, respectively using DPPH assay. Compounds 4-6 had weak to moderate activity against Escherichia coli and Staphylococcus aureus, while demonstrated promising action against Bacillus cereus with MICs 0.25, 1.0, and 1.0mg/mL, respectively. The tested compounds were inactive against Candida albicans. However, they showed selective antifungal potential toward Aspergillus fumigatus. Compounds 3 and 4 possessed quorum-sensing inhibitory activity against Chromobacterium violaceum ATCC 12472.
Phytochemical, anti-Acanthamoeba, and anti-adhesion properties of Garcinia mangostana flower as preventive contact lens solution
Acta Trop 2022 Feb;226:106266.PMID:34890540DOI:10.1016/j.actatropica.2021.106266.
Acanthamoeba keratitis infection extends due to the growing number of contact lens users. Indigenous plants including Garcinia mangostana play a vital role in human health and well being. Many species of this plant have been reported with myriads of potent medicinal properties. However, the aims of this study were, for the first time, to isolate compounds from the flower of G. mangostana and to test their anti-Acanthamoeba and anti-adhesion activity against Acanthamoeba triangularis. Powdered flowers of G. mangostana were extracted and chromatographed on a silica gel column. The structures of the compounds were established with the aid of 1H NMR. More so, the anti-Acanthamoeba and anti-adhesion properties were tested on a 96-well polystyrene microtiter plate and soft contact lenses. Scanning electron microscope (SEM) was used to determine the features of A. triangularis on contact lenses. Eight pure compounds were obtained, namely 9-Hydroxycalabaxanthone, tovophillin A, garcinone E, garcinone B, α-mangostin, gartinin, 8-deoxygartinin and γ-mangostin. The extract and pure compounds exhibited anti-Acanthamoeba activity with MIC values in the range of 0.25-1 mg/mL. In addition, the extract and α-mangostin displayed significant activity against the adhesion of A. triangularis trophozoites both in polystyrene plate and in contact lenses at 0.5 × MIC (0.25 mg/mL). Furthermore, α-mangostin has the potential to remove A. triangularis adhesion in contact lenses similar to a commercial multipurpose solution (MPS). SEM study confirmed that crude extract and α-mangostin are effective as solutions for contact lenses, which removed A. triangularis trophozoites within 24 h. Alpha-mangostin was non-toxic to Vero cells at a concentration below 39 μM in 24 h. Crude extract of G. mangostana flower and its α-mangostin serve as candidate compounds in the treatment of Acanthamoeba infection or as lens care solution, since they can be used as a source of natural products against Acanthamoeba and virulence factor associated with the adhesion of A. triangularis.
Structure activity relationship of xanthones for inhibition of Cyclin Dependent Kinase 4 from mangosteen (Garcinia mangostana L.)
Int J Nutr 2019;4(2):38-45.PMID:31363494doi
The mangosteen fruit is a popular Southeast Asian fruit consumed for centuries. There have been a variety of xanthones isolated from the fruit, bark, roots and leaves with each having unique chemical and physical properties. Previously, the most abundant xanthone α-mangostin has been shown to inhibit CDK4. Herein we describe the role of selected xanthones from the mangosteen inhibiting CDK4. The evidence we provide here is that key functional groups are required to inhibit the CDK4 protein to prevent the phosphorylation of downstream targets critical to inhibiting uncontrolled cell cycle progression. To define the properties of xanthones for inhibiting CDK4 we utilized a cell free biochemical assay to identify inhibitors of CDK4. The following xanthones were used for the analysis: α-mangostin, β-mangostin, γ-mangostin, gartanin, 8-desoxygartanin, garcinone C and garcinone D, 9-Hydroxycalabaxanthone, and 3-isomangostin These results further substantiate the unique pharmacological properties of individual xanthones and how a mixture of xanthones may be responsible for a multi-targeted effect in cell based pharmacology systems.
