alpha-Amyrin Chemical Properties,Uses,Production
Uses
a-Amyrin is a natural chemical compound of the triterpene class. It is a pentacyclic triterpenol widely distributed in nature and has been isolated from a variety of plant sources such as epicuticular wax.
Definition
ChEBI: A pentacyclic triterpenoid that is ursane which contains a double bond between positions 12 and 13 and in which the hydrogen at the 3beta position is substituted by a hydroxy group.
Biological Activity
Triterpene th at has broad-spectrum analgesic properties for which the underlying mechanism is poorly understood but which may involve the inhibition of protein kinase A (PKA).
in vivo
α-Amyrin (50, 100, 200 mg/kg orally, once daily for 42 days) can reduce the survival rate of rats with metabolic syndrome induced by high fructose diet[2].
α-Amyrin (2 or 4 mg/kg, orally) improves cognitive dysfunction caused by low cholinergic neurotransmission in mice by activating ERK and GSK-3β signaling pathways[3].
| Animal Model: | High-fructose diet (HFD)-induced metabolic syndrome in rats[2] |
| Dosage: | 50, 100, 200 mg/kg |
| Administration: | p.o. |
| Result: | Decreased systolic blood pressure, plasma glucose, total cholesterol, and plasma triglycerides. Attenuated hepatic oxidative stress as well as micro- and macrovesicular fatty changes in hepatocytes caused by HFD. |
| Animal Model: | Scopolamine-Induced Memory Impairment Mice[3] |
| Dosage: | 2 or 4 mg/kg |
| Administration: | p.o. |
| Result: | Increased the expression levels of phosphorylated extracellular signal-regulated kinase 1/2 (pERK) and phosphorylated glycogen synthase kinase-3β (pGSK-3β). |
Purification Methods
Purify it by acetylation to the acetate followed by hydrolysis and recrystallisation from aqueous MeOH or from EtOH. The acetate when crystallised from pet ether, n-heptane or CHC
