alpha-Amyrin Chemical Properties,Usage,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
