A recent article in Chemical & Engineering News describes the promising properties of curcumin, a compound derived from turmeric, in models of Alzheimer’s disease.
In addition to contributing to curry dishes’ yellow color and pungent flavor, curcumin has been a medicine in India for thousands of years. Doctors practicing traditional Hindu medicine admire turmeric’s active ingredient for its anti-inflammatory properties and have used it to treat patients for ailments including digestive disorders and joint pain.
Only in the 1970s did Western researchers catch up with Eastern practices and confirm curcumin’s anti-inflammatory properties in the laboratory. Scientists also eventually determined that the polyphenolic compound is an antioxidant and has chemotherapeutic activity.
Several research groups at Emory are investigating curcumin-related compounds.
Dermatologist Jack Arbiser has been interested in curcumin’s antiangiogenic (inhibiting blood vessel growth) properties for several years and reports that he is studying how the compound is metabolized. Chemist Dennis Liotta and his colleagues have identified relatives of curcumin that are more soluble, and thus could be more easily taken up by the body. In particular, chemist James Snyder has been a key driver in designing and synthesizing curcumin-related compounds used by several investigators at Emory and elsewhere (see figure):
Psychiatrists Thaddeus Pace and Andrew Miller have been testing whether curcumin relatives may have useful properties with depression. Specifically, the curcumin-related compounds may have the ability to interfere with the connection (YouTube video) between inflammation and depression.
Winship Cancer Institute researcher Mamoru Shoji has been exploring how to target curcumin compounds to tumor-associated endothelial cells by linking them to a clotting factor. In the Department of Gynecology and Obstetrics, Friedrich Wieser is examining whether curcumin compounds can be helpful with endometriosis.
