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, 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. 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.
Ursolic acid can serve as a starting material for synthesis of more potent bioactive derivatives, such as antitumor agents. It has been found to reduce muscle atrophy and to stimulate muscle growth in mice. Ursolic acid has potential use as a cardioprotective compound.
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. Under physiological concentrations, ursolic acid also induces eryptosis (the apoptosis-like suicidal cell death in defective red blood cells).
Occurrences in food
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.
