Scientific Essence: Cancer is considered a disease of old age, and life style plays a major role in the development of most cancers. Turmeric and its primary active ingredient curcumin has been used traditionally to treat a range of diseased states including cancer. The anti cancer-activity of curcumin against leukemia and lymphoma, gastrointestinal cancers, genitourinary cancers, breast cancer, ovarian cancer, head and neck squamous cell carcinoma, lung cancer, melanoma, neurological cancers, and sarcoma reflects its ability to affect multiple targets.


Spice healer

- Stix, Gary. Scientific American (2007), 296(2), 66-69

Scientific Essence: Turmeric, an orange-yellow powder from an Asian plant, Curcuma longa and it's primary biologically active components (curcumin and related compounds called curcuminoids) have been described as having antioxidant, anti-inflammatory, antiviral, antibacterial and antifungal properties, with potential activity against cancer, diabetes, arthritis, Alzheimer's disease and other chronic maladies. Because curcumin targets so many biological pathways, it is an attractive candidate for cancer therapy. Recent efforts to examine the possibility of using curcumin for treating cancer are discussed in the article.

Curcumin the primary active ingredient in Curcuma longa is used as a model to demonstrate the concept of green drug development. Synthetic and formulation based approaches to optimize the bioactivity of curcumin is presented.


New mechanisms and therapeutic potential of curcumin for colorectal cancer

- Villegas, Isabel; Sanchez-Fidalgo, Susana; Alarcon de la Lastra, Catalina. Molecular Nutrition & Food Research (2008), 52(9), 1040-1061

Scientific Essence: Recently a number of studies have provided evidence of the pharmacological properties of curcumin such as wound healing, antimicrobial, antiviral, antifungical, immunomodulatory, antioxidant and anti-inflammatory properties. Data from recent research provides insights into how curcumin produces effect on cancer chemoprevention and chemotherapy. There are preclinical studies which have demonstrated curcumin's ability to inhibit carcinogenesis in various types of cancers. Curcumin interacts with multiple molecular targets affecting the multistep process which leads to the onset of cancer. Curcumin is also able to stop the cell cycle, to inhibit inflammation and the oxidative stress and to induce cell-death in cancer cells. It has been shown to possess marked antiangiogenic properties. The review article provides an update of the bioavailability and pharmacokinetics of curcumin and illustrates the recently discovered pathways responsible of its anticancer potential.

Multi-targeted therapy by curcumin: how spicy is it?

- Goel, Ajay; Jhurani, Sonia; Aggarwal, Bharat B. Molecular Nutrition & Food Research (2008), 52(9), 1010-1030

Scientific Essence: Traditional medicines have been used for thousands of years. However, for most such medicines neither the active component nor their molecular targets have been established. Curcumin, the active ingredient in turmeric is an exception to this phenomenon. Separate inhibitors of cyclooxygenase-2, HER2, tumor necrosis factor, EGFR, Bcr-abl, proteasome, and vascular endothelial cell growth factor have been approved for human use by the United States Food and Drug Administration (FDA), but curcumin as a single agent can be used to down-regulate all these targets. Thus, curcumin is an attractive candidate for multi-targeted therapy, which is needed for treatment of most diseases. In addition, curcumin is inexpensive and has been found to be safe in human clinical trials. The review article studies the key molecular mechanisms involved in the effect of curcumin. The authors compare curcumin to some of the single-targeted therapies currently used for treatment of cancer.


Curcumin: a potential cancer chemopreventive agent through suppressing NF-B signaling

- Lin, Chih-Li; Lin, Jen-Kun. Journal of Cancer Molecules (2008), 4(1), 11-16.

Scientific Essence: Curcumin is a natural compound isolated from turmeric. It has strong therapeutic or preventive potential against a number of diseases. The beneficial effects of curcumin arise from its anti-oxidative, anti-inflammatory, and anti-cancerous properties. Persistent inflammation may be involved in the process of cancer development. For this reason, the overactivation of NF-B, a master switch in inflammation, is responsible for a variety of human cancers. Curcumin exercises anti-inflammatory effects substantially by interrupting NF-B signaling at various levels. The authors conclude by saying that curcumin demonstrates valuable potential in the cancer treatment through inhibiting the activity of I-B kinase, IKK. The article provides an insight into the anticancer effects of curcumin and the mechanisms of action of curcumin.
