The increasing demand for natural products as an alternative therapy for chronic diseases has encouraged research into the pharmacological importance of bioactive compounds from plants. Recently, there has been a surge of interest in the therapeutic potential of oleanolic acid (OA) in the prevention and management of chronic diseases. Oleanolic acid is a pentacyclic triterpenoid widely found in plants, including fruits and vegetables with different techniques and chromatography platforms being employed in its extraction and isolation. Several studies have demonstrated the potential therapeutic effects of OA on different diseases and their symptoms. Furthermore, oleanolic acid also serves as a framework for the development of novel semi-synthetic triterpenoids that could prove vital in finding therapeutic modalities for various ailments. There are recent advances in the design and synthesis of chemical derivatives of OA to enhance its solubility, bioavailability and potency. Some of these derivatives have also been therapeutic candidates in a number of clinical trials. This review consolidates and expands on recent reports on the biological effects of oleanolic acid from different plant sources and its synthetic derivatives as well as their mechanisms of action in in vitro and in vivo study models. This review suggests that oleanolic acid and its derivatives are important candidates in the search for alternative therapy in the treatment and management of chronic diseases.

Oleanolic acid (3β-hydroxyolean-12-en-28-oic acid) is a pentacyclic triterpenoid compound with a widespread occurrence throughout the plant kingdom. In nature, the compound exists either as a free acid or as an aglycone precursor for triterpenoid saponins, in which it can be linked to one or more sugar chains. Oleanolic acid and its derivatives possess several promising pharmacological activities, such as hepatoprotective effects, and anti-inflammatory, antioxidant, or anticancer activities. With the recent elucidation of its biosynthesis and the imminent commercialization of the first oleanolic acid-derived drug, the compound promises to remain important for various studies. In this review, the recent progress in understanding the oleanolic acid biosynthesis and its pharmacology are discussed. Furthermore, the importance and potential application of synthetic oleanolic acid derivatives are highlighted, and research perspectives on oleanolic acid are given.

Oleanolic acid (OA) is a natural, biologically active pentacyclic triterpenoid found in Cornus officinalis. Although C. officinalis and OA have antiproliferative actions, the effects and mechanisms of OA in benign prostatic hyperplasia (BPH) are unclear. We examined the effect of OA in an animal model of testosterone-induced BPH. Male rats were injected with testosterone propionate with or without OA. The inhibitory effect of OA on BPH-1 cells was determined in vitro. Rats with BPH exhibited outstanding BPH symptoms, including prostatic enlargement, upregulated dihydrotestosterone and 5α-reductase 2 levels, and histological changes. Compared with the BPH group, the OA group showed fewer pathological alterations and regular androgen events. OA inhibited prostate cell proliferation by downregulating the expression of proliferating cell nuclear antigen (PCNA) and cell cycle markers in BPH-induced animals. This indicated that OA has superior therapeutic effect in the BPH animal model than finasteride. In vitro studies demonstrated upregulation of PCNA and cell cycle proteins, whereas OA clearly reduced this upregulation. Thus, OA may inhibit the development of BPH by targeting cell cycle progression markers. These suggest that OA is a potential agent for BPH treatment.
