Abstract

Naturally occurring food-derived active ingredients have received huge attention for their chemopreventive and chemotherapy capabilities in several diseases. Rosmarinic acid (RA) is a caffeic acid ester and a naturally-occurring phenolic compound in a number of plants belonging to the Lamiaceae family, such as Rosmarinus officinalis (rosemary) from which it was formerly isolated. RA intervenes in carcinogenesis through different ways, including in tumor cell proliferation, apoptosis, metastasis, and inflammation. On the other hand, it also exerts powerful antimicrobial, anti-inflammatory, antioxidant and even antidepressant, anti-aging effects. The present review aims to provide an overview on anticancer activities of RA and to deliberate its therapeutic potential against a wide variety of diseases. Given the current evidence, RA may be considered as part of the daily diet in the treatment of several diseases, with pre-determined doses avoiding cytotoxicity.

Anti-tumor activity of rosmarinic acid in 7,12-dimethylbenz(a)anthracene (DMBA) induced skin carcinogenesis in Swiss albino mice.

R Sharmila, P. S. Manoharan (2012)

Aim of the present study was to evaluate the anti-tumor effect of orally administered rosmarinic acid in 7,12-dimethylbenz(a)anthracene (DMBA) induced skin carcinogenesis in Swiss albino mice. Phase I and II detoxication agents, lipid peroxidation byproducts, antioxidants and apoptotic biomarkers were used to assess chemopreventive efficacy of rosmarinic acid in DMBA induced skin carcinogenesis. Skin squamous cell carcinoma was induced at the shaved back of mice by applying DMBA (20 microg in 0.1 mL acetone) twice weekly for 8 weeks. Tumor formation (100%) was observed within 15 weeks of treatment in DMBA alone. Marked alterations in the status of above mentioned biomarkers were observed in tumor bearing mice. Oral administration of rosmarinic acid completely prevented the formation of skin tumors during DMBA-induced mouse skin carcinogenesis. Also, oral administration of rosmarinic acid brought back the status of phase I and phase II detoxication agents, lipid peroxidation byproducts, antioxidants and apoptotic markers (p53, Bcl-2, caspase-3 and caspase-9) in DMBA treated mice. Results of the present study suggested that rosmarinic acid had potent anticancer, anti-lipid peroxidative and apoptotic effect in DMBA-induced skin carcinogenesis.

Effects of caffeic and chlorogenic acids on the rat skeletal system.

J Folwarczna, M Pytlik, M Zych … (2015)

Caffeic acid, predominantly as esters linked to quinic acid (chlorogenic acids), is a phenolic acid present at high levels in coffee. The aim of the study was to investigate effects of caffeic and chlorogenic acids on the skeletal system of female rats with normal estrogen levels and estrogen-deficient.
