Xanthones

Bellidifolin is an orally active compound with antiproliferative, anti-inflammatory and antioxidant properties. Bellidifolin modulates key signaling pathways including STAT3, PI3K-Akt, mTOR and BRD4, and inhibits the viral protein R (Vpr). Bellidifolin induces cell cycle arrest and apoptosis, exerts significant antifibrotic effects, and protects the heart, liver and nervous system. Bellidifolin is applicable to the research of various diseases such as lung cancer, non-alcoholic fatty liver disease, myocardial hypertrophy and ischemic cranial nerve injury.

BR-xanthone A is a xanthone that can be extracted from the dried husk of mangosteen.

Epigambogic acid is a natural anti-tumor, antitussive, expectorant and anti-inflammatory compound.

Bikaverin (Lycopersin) is a reddish pigment produced by different fungal species. Bikaverin shows antibiotic properties against certain protozoa and fungi.

Cratoxylone, isolated from the bark of Cratoxylum Cochinchinense, possesses antiplasmodial activity.

3-Isomangostin hydrate (Compound 17) is an xanthone that can be isolated from Cratoxylum formosum ssp. pruniflorum and exhibits antibacterial activity.

6-Deoxyjacareubin is a natural xanthone, that can be isolated from the leaves of Vismia latifolia. 6-Deoxyjacareubin protects against non-apoptotic cell death by inhibiting ROS production. 6-Deoxyjacareubin ameliorates neurodegeneration in a mouse model of familial amyotrophic lateral sclerosis (ALS).

Norswertianin, a xanthone compound, serves as a powerful anti-glioma compound. Norswertianin induces GBM cells differentiation through oxidative stress and Akt/mTOR dependent autophagy.

Swertianolin is a xanthone glycoside. Swertianolin can be isolated from plants of the Gentianaceae family (e.g., Gentiana campestris and Swertia punicea). Swertianolin inhibits p38 phosphorylation and NF-κB activation, and reduces NO and ROS production. Swertianolin exhibits anti-Helicobacter pylori activity with an IC₅₀ of 6.1 μM and a minimum bactericidal concentration of 91.7 μM. Swertianolin modulates immune function in sepsis. Swertianolin is useful in the research of diseases such as Alzheimer's disease, hepatitis B, Helicobacter pylori infection, and sepsis.

Sibiricaxanthone B is a xanthone isolated from Polygala tenuifolia.

Fuscaxanthone C is an xanthone isolated from the stem bark of Garcinia fusca.

Cowaxanthone B is a xanthone isolated from the fruits of Garcinia cowa. Cowaxanthone B has weak antibacterial activity.

Lancerin, isolated from the root bark of Cudraniu cochinchinensis, possesses anti-lipid peroxidation.

Polygalaxanthone XI, a xanthone glycoside isolated from the cortexes of Polygala tenuifolia, can be used in the study of expectorant, and tranquilizing agent.

4-Hydroxy-9h-xanthen-9-one is a natural product.

7-O-Methylmangifer is isolated from the cortexes of Polygala tenuifolia.

Garcinone C (Standard) is the analytical standard of Garcinone C. This product is intended for research and analytical applications. Garcinone C, a xanthone derivative, is a natural compound extracted from Garcinia oblongifolia that is used as an anti-inflammatory, astringency and granulation-promoting medicine, and has potential cytotoxic effects on certain cancers. Garcinone C stimulates the expression levels of ATR and 4E-BP1, arrests the cell cycle, inhibits cell viability of the human Nasopharyngeal carcinoma (NPC) cell lines CNE1, CNE2, HK1 and HONE1 in a time‑ and dose‑dependent manner through inhibition of Hedgehog signaling pathway. Garcinone C is orally active.

Garcinone D (Standard) is the analytical standard of Garcinone D (HY-N6953). This product is intended for research and analytical applications. Garcinone D is an activator of the STAT3/Cyclin D1 and Nrf2/HO-1 pathways, and an inhibitor of CDK2/CyclinE1 (IC₅₀ for CDK2/CyclinE1 is 28.23 μM). Garcinone D promotes neural stem cell proliferation by activating STAT3 phosphorylation and Cyclin D1 expression and enhancing the Nrf2/HO-1 signaling pathway. In addition, Garcinone D blocks the tumor cell cycle by inhibiting CDK2/CyclinE1. Garcinone D can promote the proliferation of C17.2 neural stem cells and inhibit prostate and breast cancer.

beta-Mangostin (Standard) is the analytical standard of beta-Mangostin. This product is intended for research and analytical applications. beta-Mangostin (β-Mangostin) is a xanthone compound present in Cratoxylum arborescens, with antibacterial and antimalarial activities. beta-Mangostin exhibits antimycobacterial activity against Mycobacterium tuberculosis with an MIC of 6.25 μg/mL. beta-Mangostin possesses in vitro antimalarial activity against Plasmodium falciparum, with an IC50 of 3.00 μg/mL. beta-Mangostin has potent anticancer activity against various cancers (such as hepatocellular carcinoma, leukaemic).

KS 619-1 is a Ca²⁺/calmodulin-dependent cyclic nucleotide phosphodiesterase inhibitor. KS 619-1 exhibits strong inhibitory activity against this enzyme derived from bovine brain and heart, but shows weak inhibitory effects on calmodulin-independent phosphodiesterase and protein kinase C. KS 619-1 displays weak antibacterial activity against Staphylococcus aureus.
