Curcuminoids: The Novel Molecules of Nature

Curcuminoids inactivate Nuclear Factor-Kappa B (NF-κB), a key pro-inflammatory transcription factor which is involved in inflammation and immune response in diseases like cancer. NF-κB activation is necessary to determine tumor microenvironment which controls migration and metastatis of cancer cells through chemokines and their receptors and involvement of some cell adhesion molecules. Therefore inhibition of NF-κB by curcuminoids could be a new approach in treatment of cancer by immune modulation. Curcuminoids are not bioavailable and therefore there were problems in efficacy. Now by using bioavailable curcuminoid formulations the problem has been resolved to a great extent. Out of 49 placebo controlled double blind clinical trials using curcuminoids, 17 have been found to be successful. Therefore curcuminoids could be developed as an adjunct therapy for diseases like cancer to save human life.
