Lupeol is a pharmacologically active pentacyclic triterpenoid. It has several potential medicinal properties, like anticancer and anti-inflammatory activity. [1]
Lupeol is found in a variety of plants, including mango, Acacia visco and Abronia villosa. [2] It is also found in dandelion coffee. Lupeol is present as a major component in Camellia japonica leaf. [1]
The first total synthesis of lupeol was reported by Gilbert Stork et al. [3]
In 2009, Surendra and Corey reported a more efficient and enantioselective total synthesis of lupeol, starting from (1E,5E)-8-[(2S)-3,3-dimethyloxiran-2-yl]-2,6-dimethylocta-1,5-dienyl acetate by use of a polycyclization. [4]
Lupeol is produced by several organisms from squalene epoxide. Dammarane and baccharane skeletons are formed as intermediates. The reactions are catalyzed by the enzyme lupeol synthase. [5] A recent study on the metabolomics of Camellia japonica leaf revealed that lupeol is produced from squalene epoxide where squalene play the role as a precursor. [1]
Lupeol has a complex pharmacology, displaying antiprotozoal, antimicrobial, antiinflammatory, antitumor and chemopreventive properties. [6]
Animal models suggest lupeol may act as an anti-inflammatory agent. A 1998 study found lupeol to decrease paw swelling in rats by 39%, compared to 35% for the standardized control compound indomethacin. [7]
One study has also found some activity as a Dipeptidyl peptidase-4 inhibitor and prolyl oligopeptidase inhibitor at high concentrations (in the millimolar range). [8]
It is an effective inhibitor in laboratory models of prostate and skin cancers. [9] [10] [11]
As an anti-inflammatory agent, lupeol functions primarily on the interleukin system. Lupeol to decreases IL-4 (interleukin 4) production by T-helper type 2 cells. [6] [12]
Lupeol has been found to have a contraceptive effect due to its inhibiting effect on the calcium channel of sperm (CatSper). [13]
Lupeol has also been shown to exert anti-angiogenic and anti-cancer effects via the downregulation of TNF-alpha and VEGFR-2. [14]
Famous anti-inflammatory ethno-medicinal plant Camellia japonica contains anti-inflammatory component lupeol in its leaf. [1]
