OBJECTIVE: Gastric cancer is one of the most common causes of cancer-related death worldwide. Medicinal plants are one of the main sources for discovery of new pharmacological agents especially for treatment of cancers. The aim of the present study is to review pharmacotherapeutic aspects of three mostly studied phytochemicals including curcumin, quercetin, and allicin for management of gastric cancer.

METHODS: Scopus, PubMed, Web of Science, and Google Scholar were searched for the effects of curcumin, quercetin, allicin, and their analogs in gastric cancer. Data were collected up to November 2015. The search terms were"curcumin,""quercetin,""allicin,"and"gastric cancer"or"cancer."

RESULTS: Curcumin demonstrated anti-angiogenic, anti-proliferative, anti-metastatic, pro-apoptotic, and anti-helicobacter activities. Quercetin inhibited cell growth and induced apoptosis, necrosis, and autophagy as well as anti-Helicobacter activity. Allicin showed apoptotic and anti-Helicobacter properties. All three natural compounds had low bioavailability.

CONCLUSIONS: Although preclinical studies demonstrated the activity of curcumin, quercetin, and allicin in gastric cancer, clinical trials are needed to confirm their effectiveness. Applying their possible synergistic action and suitable drug delivery system in clinical studies can be also an attractive approach with the purpose of finding new extremely efficient anti-gastric cancer agents. Curcumin, quercetin, and allicin seem to be good candidates for management of gastric cancer through their pro-apoptotic, anti-proliferative, and anti-helicobacter activities.
