Abstract:

Resveratrol, a non-flavonoid phenolic phytochemical present in red grapes and berries, has been reported to have significant health benefits. Resveratrol is known for its chemopreventive and chemotherapeutic effects in multiple cancers as well as cardiovascular and inflammatory diseases. But its higher lipophilicity, poor aqueous solubility and bioavailability remains a challenge for its usage as an effective chemopreventive and chemotherapeutic agent. To overcome this,we have prepared a biocompatible calcium phosphate encapsulated resveratrol (Nanoresveratrol; NRV) and studied its antioxidant, anti-inflammatory and anti-cancer activities in the present study.Nanoresveratrol, unlike resveratrol, readily dispersed in aqueous media and showed a sustained release. Nanoresveratrol (NRV) and resveratrol (RV) showed comparable antioxidant activities. The anti-inflammatory and anticancer activities of nanoresveratrol were studied for its inhibitory effect on 7, 12-dimethylbenz[a]anthracene (DMBA)-induced/12-O-tetradecanoylphorbol-13-acetate (TPA) promoted skin inflammation and tumorigenesis mouse model. Nanoresveratrol showed a significant decrease of TPA-induced skin edema, ODC activity and thymidine incorporation when compared to resveratrol. Nanoresveratrol also inhibited chemical-induced tumorigenesis.Overall, the study results support that nanoresveratrol may represent a potential anti-cancer agent and warrants further investigations for the treatment of skin cancer.
