Chemische Eigenschaften
red-orange powder
Verwenden
antibacterial, antineoplastic, cathartic, tyrosine kinase inhibitor
Verwenden
Emodin has been used:
- to investigate its regulatory mechanisms on lipopolysaccharide (LPS)-induced inflammatory injury in myocarditis
- as a reference standard for the development and validation of high performance liquid chromatography (HPLC)-photodiode array (PDA) assay method
- to inhibit Tau aggregation
- for direct binding assay
Verwenden
Occurs mostly as the rhamnoside (see Frangulin) in rhubarb root. Cathartic.
Definition
ChEBI: Emodin is a trihydroxyanthraquinone that is 9,10-anthraquinone which is substituted by hydroxy groups at positions 1, 3, and 8 and by a methyl group at position 6. It is present in the roots and barks of numerous plants (particularly rhubarb and buckthorn), moulds, and lichens. It is an active ingredient of various Chinese herbs. It has a role as a tyrosine kinase inhibitor, an antineoplastic agent, a laxative and a plant metabolite. It is functionally related to an emodin anthrone. It is a conjugate acid of an emodin(1-).
Allgemeine Beschreibung
Orange needles or powder.
Air & Water Reaktionen
Insoluble in water.
Reaktivität anzeigen
Emodin may be sensitive to prolonged exposure to light. Probably a weak acid due to the phenolic functional groups.
Health Hazard
ACUTE/CHRONIC HAZARDS: When heated to decomposition Emodin emits acrid smoke and irritating fumes.
Brandgefahr
Flash point data for Emodin are not available; however, Emodin is probably combustible.
Biologische Aktivität
Naturally occurring anthraquinone that displays a range of biological activities. Exhibits anti-inflammatory, antitumor and neuroprotective effects.
Biochem/physiol Actions
Cell permeable: yes
läuterung methode
Archin forms orange needles from EtOH, Et2O, *C6H6, toluene or pyridine. It sublimes above 200o at 12mm. [Tutin & Clewer J Chem Soc 99 946 1911, IR: Bloom et al.
