Curcumin anticancer effects

Studies during the past century have shown the anticancer effect of curcumin against cancers of various anatomical sites. The preclinical anticancer potential of curcumin has been established both in vitro and in vivo, which lead to the clinical trials with this promising molecule. Below is a description of the studies, that have evaluated the preclinical and clinical anticancer activity of curcumin. 

The anticancer effect of curcumin in murine thymoma cells was found to be due to the blocking of IL-1 signaling by the inhibition of the recruitment of the IL-1 receptor-associated kinase (IRAK) [Jurrmann et al., 2005]. A recent study showed that curcumin could prevent tumor-induced thymic atrophy in thymic T cells, leading to the neutralization of tumor-induced oxidative stress and the restoration of NF-kB activity and the re-education of the TNF-a signaling pathway, resulting in thymic protection [Bhattacharyya et al., 2007]. 

Several in vivo studies have established the chemopreventive as well as anticancer effect of curcumin against a variety of cancers, as summarized in...

The amphiphilic molecules constituting the micelles can be surfactants, like sodium dodecyl sulfate (SDS) for the solubilization of artemisinin and curcumin or for the delivery of polyphe-nolic fractions from Hamamelis virginianaP The micelles can also be formed of synthetic block copolymers. For example, copolymers of caprolactone 2-(methacryloyloxy)ethyl ester units with poly(meth)acrylic acid side chains have been self-assembled in micelles of quercetin associated with indomethacin for the treatment of inflammatory diseases (Figure 36.10). Resveratrol has been loaded into PCL-PEG micelles for its protective effect against oxidative stress. An aqueous formulation of luteolin has been developed with the same PCL-PEG micelles, with potential anticancer effect. ...
