| Hazard Information | Back Directory | [Description]
Auraptene (495-02-3) is a bioactive terpenoid occurring in a variety of citrus fruits and possessing therapeutic potential.1?? Displays neuritogenic activity2?and neuroprotective effects via suppression of inflammation and induction of GDNF and BDNF in neuronal cells3. Attenuates ROS production and enhances mitochondrial respiration which mitigates Parkinson’s disease-like behavior.4?Displays hepatoprotective5?and chemopreventive activity6. | [Chemical Properties]
Soluble in organic solvents such as methanol, ethanol, and DMSO, it comes from the immature or nearly mature dried outer peel of the Rutaceae plant Huazhou pomelo or pomelo; citrus red. | [Uses]
antineoplastic, apoptosis inducer | [Uses]
Auraptene is a natural bioactive monoterpene coumarin ether. Auraptene has shown a remarkable effect in the prevention of degenerative diseases. | [Definition]
ChEBI: Auraptene is a member of the class of coumarins that is umbelliferone in which the phenolic hydrogen has been replaced by a geranyl group. Ii is isolated from several edible fruits and vegetables and exhibits a variety of therapeutic properties. It has a role as a plant metabolite, an antineoplastic agent, an apoptosis inducer, a dopaminergic agent, a neuroprotective agent, an antihypertensive agent, a gamma-secretase modulator, a vulnerary, an EC 2.7.11.24 (mitogen-activated protein kinase) inhibitor, a PPARalpha agonist, a gastrointestinal drug, a matrix metalloproteinase inhibitor, an antioxidant and a hepatoprotective agent. It is a member of coumarins and a monoterpenoid. It is functionally related to an umbelliferone. | [Biological Activity]
Anti-inflammatory and chemopreventive compound. Exerts tumor preventive effects through apoptosis. Suppresses cell proliferation and lipid peroxidation. Acts as an agonist of PPARs. Induces phase II drug-metabolizing enzymes. | [Synthesis]
Synthesis procedure for Aurapten (5): propylene oxide (159 μL, 0.80 mmol) was added to a stirred mixture of 7-hydroxycoumarin (100 mg, 0.62 mmol) and anhydrous potassium carbonate (171 mg, 1.24 mmol) in anhydrous N,N-dimethylformamide (5 mL) under argon protection. The reaction mixture was stirred under reflux conditions for 3 hours. After completion of the reaction, the reaction mixture was neutralized with 1 M aqueous hydrochloric acid. The brown residue obtained was dissolved in dichloromethane (20 mL), washed sequentially with water (2 x 20 mL), saturated saline (30 mL) and dried with anhydrous sodium sulfate. The solvent was removed under reduced pressure to give a brown oil, which was purified by fast column chromatography using diethyl ether-hexane (1:1) as eluent to give a white powdery product 5 (181 mg, 76% yield). The structure of the product was confirmed by 1H NMR, 13C NMR and high resolution fast atom bombardment mass spectrometry (HR-FABMS). | [in vivo]
Auraptene (200, 500 ppm, mixed in the diet, p.o.) delays the tumor progression of breast cancer rats by inhibiting cyclin D1 protein[3].
Auraptene (100, 500 ppm, mixed in the diet, p.o.) alleviates gastritis by reducing Helicobacter pylori colonization and pro-inflammatory mediator production in C57BL/6 mice[4].
