Ursolic Acid (UA), identified by its CAS number 77-52-1, is a naturally occurring pentacyclic triterpenoid found abundantly in many fruits, herbs, and spices. Its rich profile of biological activities, including significant anti-inflammatory and antioxidant effects, has garnered considerable attention in both pharmaceutical and nutraceutical research. This review delves into the core value of Ursolic Acid, exploring its mechanisms of action and diverse applications.

One of the most compelling aspects of Ursolic Acid is its potent anti-inflammatory capability. By modulating key signaling pathways such as NF-κB and MAPK, UA effectively reduces the production of pro-inflammatory cytokines like TNF-α and IL-6. This makes it a promising candidate for managing chronic inflammatory conditions. Furthermore, its antioxidant activity, demonstrated through free radical scavenging and the enhancement of endogenous antioxidant enzymes, plays a crucial role in protecting cells from oxidative stress, a factor implicated in numerous diseases.

The anticancer properties of Ursolic Acid are also a major focus of research. Studies indicate that UA can induce apoptosis (programmed cell death) and inhibit cell cycle progression in various cancer cell lines. These effects are mediated through pathways involving p53 activation, AMPK signaling, and modulation of proteins like Bcl-2, underscoring its potential as a chemopreventive and therapeutic agent.

While Ursolic Acid offers significant health benefits, its low oral bioavailability presents a challenge for widespread clinical application. Researchers are actively exploring innovative delivery systems, such as nanoformulations (liposomes, nanoparticles, and micelles), to enhance its solubility, stability, and targeted delivery. These advancements are critical for maximizing the therapeutic efficacy of UA.

Beyond human health, Ursolic Acid also finds applications in animal husbandry, where it is used for its anti-inflammatory, antiviral, and intestinal health-promoting properties. Its potential to act as a natural alternative to antibiotics in animal feed is also being investigated, aligning with the growing demand for sustainable agricultural practices.

In summary, Ursolic Acid (CAS 77-52-1) stands out as a valuable natural compound with a broad spectrum of beneficial effects. Continued research into its mechanisms of action, coupled with advancements in drug delivery systems, promises to unlock its full therapeutic potential across various industries.
