General description

Ursolic acid (UA) is a hydroxyl pentacyclic triterpenoic acid (HPTA), which exhibits anti-bacterial, anti-cancer, anti-oxidative and anti-inflammatory effects. It can also promote neuroregeneration after peripheral nerve injury. UA can enhance sleep duration by activating the GABAergic neurotransmitter system. [GABA= γ-aminobutyric acid]

Application

Ursolic acid can be used as a starting material to synthesize ethoxycarbonylmethyl ursolate (ECU) by reacting with ethyl chloroacetate. ECU is further used as a key intermediate in the total synthesis of a biologically important compound 3-acetyl-2-[(un)substituted phenyl]-2,3-dihydro-1,3,4-oxadiazol-5-Me 3-O-acetylursolate. Ursolic acid can also be used to prepare novel heterocyclic derivatives for various activity studies.

Biochem/physiol Actions

Triterpenoid found in a variety of fruits, including apples. Cardioprotective and anti-tumor agent. Under study as a potential Alzheimer′s disease therapeutic due to its inhibitory effect on the interactions between amyloid-β and the CD36 receptor.
