an overview ScienceDirect Topics Feb 4 2023 A review of the current knowledge of xanthone biosynthesis and trafficking in plant organisms with a focus on the precursors and enzymes involved Xanthones are a class of secondary metabolites with diverse structures and biological activities widely distributed in nature and produced by plants fungi and lichens Here we emphasize that specific xanthone derivatives in future trials is important αmangostin is the most widespread studied and exhibited the highest activity against breast cancer human leukemia lung cancer pheochromocytoma and colorectal carcinoma Xanthones show promise in diabetes with antioxidant and anti Xanthone123triazole dyads were obtained by two different approaches both starting from E24arylbut1en3yn1ylchromones previously obtained by a basecatalysed aldol reaction of 2methylchromone and arylpropargyl aldehydes 173 While the first approach adopted a methodology in which the xanthone core is primarily constructed

found in many plants and fruits as a phytochemical Xanthone Biosynthetic Pathway in Plants A Review PMC Phytochemical Screening Antioxidant AntiCytotoxic and Feb 6 2010 Notes Go To Top Data from NIST Standard Reference Database 69 NIST Chemistry WebBook The National Institute of Standards and Technology NIST uses its best efforts to deliver a high quality copy of the Database and to verify that the data contained therein have been selected on the basis of sound scientific judgment Xanthone NIST Chemistry WebBook Xanthones are organic compounds with a C6C1C6 chain and a heterocyclic ring They are widely distributed in plants fungi and lichens and have various biological activities and taxonomic significance Xanthone C13H8O2 CID 7020 PubChem Jul 29 2024 Xanthones are polyphenolic compounds found in plants that have antioxidant antiinflammatory and insulinsensitizing effects Learn how xanthones can improve glucose metabolism prevent oxidative stress and ameliorate diabetes complications Dietary Xanthones SpringerLink Xanthone is a tricyclic polyphenol found in some higher plants fungi and lichens Learn about its rental 88 slot chemical structure classification biosynthesis and pharmacological properties from various chapters and articles on ScienceDirect Xanthone is the parent compound of the xanthone class consisting of xanthene bearing a single oxo substituent at position 9 It has a role as an insecticide An Update on the Anticancer Activity of Xanthone Derivatives Oct 1 2020 The therapeutic efficacy of the contemporary antiinflammatory drugs are well established however prolonged use of such can often lead to serious and lifethreatening side effects Xanthone is an aromatic oxygenated heterocyclic molecule with a dibenzoγpirone scaffold known as 9Hxanthen9one with the molecular formula of C 13 H 8 O 2 The number and class of rings A and B derive from the biosynthetic pathways in higher plants leading to the acetatederived Aring carbons 14 and the shikimic acid pathway Xanthones Biosynthesis and Trafficking in Plants Fungi and Xanthones Encyclopedia MDPI Apr 8 2022 Proposed pathways for a plethora of other downstream xanthone derivatives including swertianolin and gambogic acid derived from 135THX as well as gentisin hyperixanthone A αmangostin and mangiferin derived from 137THX have also been thoroughly covered This review reports one of the most complete xanthone pathways in plants In contrast to xanthone Cglucosides xanthone Oglucosides are glucosides that are linked to the tricyclic body of xanthones by an oxygen atom Xanthone glucoside is generally found at the C1 position of the xanthone nucleus Glucosides are typically monosaccharides or disaccharides that contain glucose xylose rhamnose and other glycosyl Xanthone Glucosides Isolation Bioactivity and Synthesis The study was designed to investigate the chemical composition and the biological effects of G parviflora and V polyanthes ethanolic extracts in vitro Total content of phenols flavonoids and tannins was quantified by spectrophotometry chemical Xanthone exhibits several medicinal activities and especially it inhibits the growth of cancer cells However the use of xanthone is limited because of its low aqueous solubility and systemic toxicity Xanthone is a phenolic compound with a planar dibenzoγpyron scaffold It contains conjugated aromatic ring system that is composed of two rings carbons 14 ring A and carbons 58 ring B and attached together through an oxygen atom and a carbonyl group ring C to form the basic skeleton of xanthone known as 9Hxanthen9one Feb 23 2021 2 Xanthone A Privileged Scaffold According the concept of Evans et al the xanthone nucleus could be considered as a privileged structure taking into account its binding to multiple unrelated classes of protein receptors as high affinity ligands Following several authors associated the xanthone to the privileged structure Xanthone with an IUPAC name of 9Hxanthen9one is a heterocyclic compound with a dibenzoγpyrone framework with a basic molecular formula of C 13 H 8 O 2 The general structure of xanthone and its atom numbering is shown in +98 kode negara mana Figure 1
