S been described that polyphenols inhibit carcinogenesis and induce PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/21994079 tumor cell death . Among the polyphenols, the interest in two of them has enhanced in the last years. Papers describing curcumin andor resveratrol are present in almost fifteen thousand of publications in the final ten years. Each polyphenols have been described as promising anticancer compounds; nonetheless, the mode of action for them are nevertheless unclear and not fully comprehended [2]. Curcumin (diferuloylmethane) is definitely an active ingredient from the perennial herb Curcuma longa, also called turmeric. The yellow color of this polyphenol is chemically related to its major fraction, which contains curcuminoids [3]. Curcumin has been made use of for a long time in nations like China and India as standard medicines. This ancient remedy has brought the focus of scientific neighborhood for any wide range of beneficial properties which includes antiinflammatory, antioxidant and chemopreventive [4,5]. By the other hand, resveratrol (trans3,five,four trihydroxystilbene) is really a stilbene phytoalexin synthetized by several different plants, specially vine in response to fungi infections and ultraviolet radiation [6]. This compound is discovered at higher concentration in grapes and red wine, which antioxidant effect is nicely established in various distinctive assays. Resveratrol has been investigated as prospective compound for the therapy of a number of diseases, regulation of immune method and chemoprevention [7,8].Nutrients 206, 8, 628; doi:0.3390nu80628 mdpijournalnutrientsNutrients 206, 8,two ofIn Nutrients 206, 8, 628 clinical research, the typical challenge regarding both compounds may be the reduced aqueous two of 48 solubility and low bioavailability [3,9]. To be able to overcome these limitations, research have possible compound for the therapy of a number of illnesses, regulation of immune method and been conducted employing various methods. For curcumin, for instance, these strategies involve: chemoprevention [7,8]. (a) complexation with metal ions, including Zn2 , Cu2 , Se2 and Mg2 [2]; the coadministration with (b) lowered aqueous In clinical studies, the typical challenge concerning both compounds is piperine, which inhibits the phase II metabolism of curcumin and increases its bioavailability [3,4]; solubility and low bioavailability [3,9]. In order to overcome these limitations, research happen to be (c) Pharmaceutical technologies like micelles formation and nanoencapsulation were utilised to performed applying numerous tactics. For curcumin, for instance, these tactics include: (a) complexation with metal curcumin Zn2, Cu , Se2 and Mg2 [2]; (b) coadministration with increase the bioavailability ofions, such as [53]. MedChemExpress F 11440 2Resveratrol has been extensively studied aiming piperine, which inhibits the phase II metabolism of curcumin and increases its bioavailability [3,4]; to improve its aqueous solubility and bioavailability in addition to a variety of techniques were used (c) Pharmaceutical technologies such as micelles formation and nanoencapsulation have been used to to achieve this purpose [24], including: (a) nanoencapsulation [258]; (b) prodrug approach [29]; raise the bioavailability of curcumin [53]. Resveratrol has been extensively studied aiming to and (c)improve its aqueous solubility and bioavailability plus a quantity of tactics have been employed to achieve low or coadministration with piperine [30]. These polyphenols have exhibited really notobserved toxic like: (a) nanoencapsu.
