|Arjunolic acid: a new multifunctional therapeutic promise of alternative medicine.[Pubmed: 23402784]|
|In recent years, a number of studies describing the effective therapeutic strategies of medicinal plants and their active constituents in traditional medicine have been reported. Indeed, tremendous demand for the development and implementation of these plant derived biomolecules in complementary and alternative medicine is increasing and appear to be promising candidates for pharmaceutical industrial research. These new molecules, especially those from natural resources, are considered as potential therapeutic targets, because they are derived from commonly consumed foodstuff and are considered to be safe for humans. |
METHODS AND RESULTS:
This review highlights the beneficial role of Arjunolic acid, a naturally occurring chiral triterpenoid saponin, in various organ pathophysiology and the underlying mechanism of its protective action. Studies on the biochemistry and pharmacology suggest the potential use of Arjunolic acid as a novel promising therapeutic strategy. WHAT THE READERS WILL GAIN: The multifunctional therapeutic application of Arjunolic acid has already been documented by its various biological functions including antioxidant, anti-fungal, anti-bacterial, anticholinesterase, antitumor, antiasthmatic, wound healing and insect growth inhibitor activities. The scientific basis behind its therapeutic application as a cardioprotective agent in traditional medicine is justified by its ability to prevent myocardial necrosis and apoptosis, platelet aggregation, coagulation and lowering of blood pressure, heart rate, as well as cholesterol levels. Its antioxidant property coupled with metal chelating property (by its two hydroxyl groups) protects different organs from metal and drug-induced organ pathophysiology. Arjunolic acid also plays a beneficial role in the pathogenesis of diabetes and its associated complications. The mechanism of cytoprotection of Arjunolic acid, at least in part, results from the detoxification of reactive oxygen species (ROS) produced in the respective pathophysiology. In addition to its other biological functions, it also possesses vibrant insecticidal properties and it has the potential to be used as a structural molecular framework for the design of molecular receptors in the general area of supramolecular chemistry and nanochemistry. Esters of Arjunolic acid function as organogelators which has wide application in designing thermochromic switches and sensor devices. Arjunolic acid derived crown ether is an attractive candidate for the design of molecular receptors, biomimetics and supramolecular systems capable of performing some biological functions.
This review would provide useful information about the recent progress of natural product research in the domain of clinical science. This review also aims to untie the multifunctional therapeutic application of Arjunolic acid, a nanometer-long naturally occurring chiral triterpenoid biomolecule.

|Anti-tumor activity of arjunolic acid against Ehrlich Ascites Carcinoma cells in vivo and in vitro through blocking TGF-β type 1 receptor.[Pubmed: 27470335 ]|
|We aimed to evaluate therapeutic potential of Arjunolic acid (AA), in Terminalia Arjuna bark, on Ehrlich Ascites carcinoma (EAC) in-vivo and in-vitro. EAC was induced in fifty female Swiss albino mice. |
METHODS AND RESULTS:
Two doses of AA was used 100 and 250mg/kg. Arjunulic acid reduced tumor volume and cells count. AA decreased EAC cells viability and increased cell toxicity. Moreover, AA reduced TNF-α, IL-1β, TGF-β, TGF-β type I receptor and latency-associated peptide levels associated with elevated IL-10 in-vivo and in-vitro.
In conclusion, AA produced antitumor activity against EAC by increasing cytotoxicity and apoptosis and partially blocking the TGF-βR1 and affecting inflammatory cytokine levels.

|Antiallergic and anti-asthmatic activities of the alcoholic extract of Terminalia arjuna and arjunolic acid.[Reference: WebLink]|
|In the present study, the alcoholic extract of Terminalia arjuna (TA) and Arjunolic acid (AA) were studied for its anti-asthmatic and anaphylactic activity. |
METHODS AND RESULTS:
Treatment with TA (250 & 500 mg/kg) and AA (50 & 100 mg/kg) has shown significant protection against mast cell disruption in rats induced by compound 48/80. TA and AA also protected the guinea pig against histamine as well as acetylcholine induced bronchospasm. Both TA & AA exhibited better protection against histamine release than against acetylcholine release.
Anti-asthmatic and anaphylactic activity may be possibly due to membrane stabilizing potential and inhibition of antigen induced histamine and acetylcholine release.

|Protective effects of arjunolic acid against cardiac toxicity induced by oral sodium nitrite: effects on cytokine balance and apoptosis.[Pubmed: 25064822]|
|Sodium nitrite, a preservative used in meat products, helps in the production of free radicals, leading to increased lipid peroxidation, which plays a vital role in posing toxic effects in different body organs. On the other hand, Arjunolic acid possesses antioxidant properties and plays protective roles against chemically induced organ pathophysiology. We investigated the effect of sodium nitrite on cardiac tissue in rats on the inflammatory cytokine balance and the type of induced apoptosis, and we analyzed the protective role of Arjunolic acid.
METHODS AND RESULTS:
Sixty adult male Sprague-Dawley rats were injected with 80mg/kg sodium nitrite in the presence/absence of Arjunolic acid (100 and 200mg/kg). Cardiac pro-inflammatory cytokines (TNF-α and IL-1β), c-reactive protein (CRP) and anti-inflammatory cytokines (IL-4 and IL-10) were measured by ELISA. Cardiac mitochondrial activity (cytochrome-C-oxidase), JNK activation and apoptosis (caspase-3, caspase-8 and caspase-9) were assessed.
Sodium nitrite resulted in increased TNF-α (1.6-fold), IL-1β (3.7-fold) and CRP (2.4-fold) levels accompanied by 52%, 59% and 40% reductions in IL-10, IL-4 and cytochrome-C-oxidase, respectively, as well as enhanced JNK, caspase-3, caspase-8 and caspase-9 activities. Arjunolic acid markedly ameliorated these effects.
Arjunolic acid attenuated sodium nitrite-induced cardiac damage in rats and restored the normal balance between pro- and anti-inflammatory cytokines. Moreover, Arjunolic acid protected cardiac tissues from both extrinsic and intrinsic cell death pathways.

|Cisplatin-induced testicular toxicity in rats: the protective effect of arjunolic acid.[Pubmed: 25130312 ]|
METHODS AND RESULTS:
In the present study, the effect of Arjunolic acid on testicular damage induced by intraperitoneal injection of rats with 7 mg/kg cisplatin was studied. Cisplatin induced a significant reduction in testicular weights, plasma testosterone, and testicular reduced glutathione levels in addition to a significant elevation of testicular malondialdehyde levels and testicular gene expressions of inducible nitric oxide synthase (iNOS), tumor necrosis factor-α (TNF-α), and p38 mitogen-activated protein kinase (MAPK) when compared with the control group (p < 0.05). Lower tubular diameters and depletion of germ cells and irregular small seminiferous tubules with Sertoli cells only were observed in the cisplatin group. Arjunolic acid administration significantly corrected the changes in both biochemical and histopathological parameters.
Arjunolic acid plays a significant protective role against cisplatin-induced testicular injury by attenuating oxidative stress parameters along with downregulation of iNOS, TNF-α, and p38-MAPK testicular expressions.
