background & aim: free radicals are produced in ischemic processes. nerve damage caused by free radicals may play a role in neurological diseases and antioxidants are protective activity. ellagic acid is a polyphenol compound with antioxidant properties which is found in fruits like pomegranate, blackberry, and all types of mulberry. this study aimed to evaluate the effect of 14 days of ora...

Chlorophyllin (CHL), a water-soluble, semi-synthetic derivative of chlorophyll and ellagic acid (EA), a naturally occurring polyphenolic compound in berries, grapes, and nuts have been reported to exert anticancer effects in various human cancer cell lines and in animal tumour models. The present study was undertaken to examine the mechanism underlying chemoprevention and changes in gene expres...

It is well known that dietary phenolic compounds can elicit vital cellular responses such as cytotoxicity, cell cycle arrest and apoptosis by activating a cascade of molecular events. Ellagic acid is one of these phenolic compounds, but the exact mechanism of its action is still unclear. The objective of this study was to investigate ellagic acid-induced cell cycle arrest and apoptosis in T24 h...

The reaction coordinate between a typical ultimate carcinogen benzo[a]pyrene-7,8-diol-9,10-epoxide (BPDE) and ellagic acid, a proven chemopreventive agent active against cancers caused by polycyclic aromatic hydrocarbons (PAHs), was examined by density functional theory (DFT) and semiempirical MO calculations, and activation energy was calculated. The effect of a polar environment was included ...

Ellagic acid is a naturally occurring plant phenol which has been shown to reduce the incidence of a number of carcinogen-induced tumors including methylbenzylnitrosamine (MBN)-induced esophageal carcinoma in the rat. The postulated mechanism of MBN-induced esophageal carcinogenesis is through oxidation of MBN to form benzaldehyde and an activated metabolite which methylates DNA forming a varie...

Purpose: To investigate if ellagic acid exerts neuroprotective effects in hypoxic-ischemic (HI) brain injury by inhibiting apoptosis and inflammatory responses. Methods: Separate groups of rat pups from post-natal day 4 (D4) were administered with ellagic acid (10, 20 or 40 mg/kg body weight) orally till post-natal day 10 (D10). On D10, the rats were subjected to HI brain injury. Following HI i...

Chronic p.o. feeding of small amounts of ellagic acid, a naturally occurring dietary plant phenol, to BALB/c mice in drinking water afforded significant protection against skin tumorigenesis induced by 3-methylcholanthrene, a polycyclic aromatic hydrocarbon carcinogen. A significant increase in the latent period for the development of skin tumors by 3-methylcholanthrene was observed in the ella...

This study evaluated the protective effect of ellagic acid on sodium valproate-induced sperm abnormalities in male Wistar rats. A total of 30 rats were grouped into five groups, each having 6 animals. Vehicle, sodium valproate (400 mg/kg) and ellagic acid (10, 25, 50 mg/kg) were given orally from day 1 to day 7, and ellagic acid was continued for 3 more days. On day fourteen, animals were sacri...

The effect of ellagic acid on oxidative stress and hypertension induced by Nω-Nitro-L-arginine methyl ester hydrochloride (L-NAME) was investigated. Male Sprague-Dawley rats were administrated with L-NAME (40 mg/kg/day) for five weeks. L-NAME induced high systolic blood pressure (SBP) and increased heart rate (HR), hindlimb vascular resistance (HVR) and oxidative stress. Concurrent treatment wi...
