Ursolic acid (sometimes referred to as urson, prunol, malol, or 3-beta-3-hydroxy-urs-12-ene-28-oic-acid), is a pentacyclic triterpene acid, used in cosmetics that is also capable of inhibiting various cancer cell types by inhibiting the STAT3 activation pathway,[2][3] one of which includes human fibrosarcoma by reducing expression of matrix metalloproteinase-9 via glucocorticoid receptors. It may also decrease proliferation of cancer cells and induce apoptosis.[4] Ursolic acid has also been shown to inhibit JNK expression and IL-2 activation of JURKAT leukemic T Cells leading to the reduction in proliferation and T cell activation.[5]

Ursolic acid can serve as a starting material for synthesis of more potent bioactive derivatives, such as antitumor agents.[6] It has been found to reduce muscle atrophy and to stimulate muscle growth in mice.[7][8] Ursolic acid has potential use as a cardioprotective compound.[9]

Ursolic acid was found to be a weak aromatase inhibitor (IC50 = 32 μM).[10]

Ursolic acid has been shown to increase the amount of muscle and brown fat and decrease white fat obesity and associated conditions when added to diets fed to mice.[11] Under physiological concentrations, ursolic acid also induces eryptosis (the apoptosis-like suicidal cell death in defective red blood cells).[12]

Natural occurrences[edit]

Ursolic acid is present in many plants, such as Mirabilis jalapa.[13]

Occurrences in food[edit]

including apples, basil, bilberries, cranberries, elder flower, peppermint, rosemary, lavender, oregano, thyme, hawthorn, and prunes. Apple peels contain large quantities of ursolic acid and related compounds.[14]
