Amongst the polyphenols, the interest in two of them has enhanced inside the final years. Papers describing curcumin andor resveratrol are present in nearly fifteen thousand of publications within the last ten years. Both polyphenols happen to be described as promising anticancer compounds; nevertheless, the mode of action for them are still unclear and not fully comprehended [2]. Curcumin (diferuloylmethane) is definitely an active ingredient of the perennial herb Curcuma longa, also known as turmeric. The yellow color of this polyphenol is chemically associated to its main fraction, which contains curcuminoids [3]. Curcumin has been applied for a extended time in nations like China and India as conventional medicines. This ancient remedy has brought the focus of scientific community to get a wide variety of effective properties including antiinflammatory, antioxidant and chemopreventive [4,5]. By the other hand, resveratrol (trans3,5,4 trihydroxystilbene) is usually a stilbene phytoalexin synthetized by various plants, specially vine in response to fungi infections and ultraviolet radiation [6]. This compound is located at higher concentration in grapes and red wine, which antioxidant effect is well established in numerous various assays. Resveratrol has been investigated as potential compound for the remedy of a number of illnesses, regulation of immune method and chemoprevention [7,8].Nutrients 206, eight, 628; doi:0.3390nu80628 mdpijournalnutrientsNutrients 206, eight,2 ofIn Nutrients 206, eight, 628 clinical research, the prevalent situation with regards to both compounds would be the lowered aqueous two of 48 solubility and low bioavailability [3,9]. So that you can overcome these limitations, studies have potential compound for the remedy of quite a few illnesses, regulation of immune technique and been conducted utilizing quite a few techniques. For curcumin, by way of example, these approaches include things like: chemoprevention [7,8]. (a) complexation with metal ions, for instance Zn2 , Cu2 , Se2 and Mg2 [2]; the coadministration with (b) reduced aqueous In clinical studies, the widespread issue 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]. So as to overcome these limitations, research have already been (c) Pharmaceutical technologies for example micelles formation and nanoencapsulation were employed to conducted applying many approaches. For curcumin, for example, these techniques include things like: (a) complexation with metal curcumin Zn2, Cu , Se2 and Mg2 [2]; (b) coadministration with raise the bioavailability ofions, such as [53]. 2Resveratrol has been extensively studied aiming piperine, which inhibits the phase II metabolism of curcumin and increases its bioavailability [3,4]; to boost its aqueous solubility and bioavailability plus a variety of methods were applied (c) Pharmaceutical technologies such as micelles formation and nanoencapsulation have been utilized to to attain this goal [24], like: (a) nanoencapsulation [258]; (b) prodrug approach [29]; boost the bioavailability of curcumin [53]. Resveratrol has been extensively studied aiming to and (c)enhance its aqueous solubility and bioavailability plus a variety of tactics were applied to PD 151746 site achieve low or coadministration with piperine [30]. These polyphenols have exhibited incredibly notobserved toxic including: (a) nanoencapsu.
