Abstract
Abstract
Objectives
The neem (Azadirachta indica) have been used in herbal medicine for the treatment of multiple diseases, particularly cancer. The mechanism of anti-cancer properties of neem are far from clear. However, it is well accepted that anti-cancer effects of neem is mediated via its hepatic anti-oxidant activity. In the present review, we are going to classify in vitro and in vivo studies about anti-cancer activity of neem via its hepatic anti-oxidant activity. We also summarize its active ingredients and some therapeutic and toxic dosage forms.
Methods
A systematic search in the literature was performed in PubMed, Scopus, Embase, Cochrane Library, Web of Science, as well as Google Scholar pre-print database using all available MeSH terms for neem, A. indica, anti-cancer, anti-tumor, carcinogen, liver, antioxidant activity, neem ingredients, and glutathione. Electronic database searches combined and duplicates were removed.
Results
The neem plant have been used in herbal medicine for the treatment of various diseases, particularly cancer. The mechanisms of anti-cancer effects of neem are far from clear. Cancerous cells growth can induce imbalance the oxidant and anti-oxidant activity in various organs particularly in the liver. Therefore, it seems that neem have anti-cancer effects via restore of the antioxidant disturbances close to the control ones in the liver. Additionally, administration of neem extract can induce oncostatic potential via several mechanism including; suppression of the NF-κβ pathway, increased expression of tumor suppressor (such as p53 and pTEN), decreased expression of oncogenes (such as c-Myc), and increased apoptosis in cancerous cells. The median lethal dose (LD50) value for extracts of neem was higher than 2,500 mg/kg.
Conclusions
It is suggested that neem plays pivotal role in the prevention and treatment of cancer via its hepatic antioxidant activity. Indeed, application of neem extract can decreased tumor growth via restore of the antioxidant disturbances close to the control ones in the liver.
