Seeking to improve on nature, scientists used a spice-based compound as a starting point and developed synthetic molecules that, in lab settings, are able to kill cancer cells and stop the cells from spreading.

The researchers are combining organic chemistry, computer-aided design and molecular biology techniques in developing and testing pharmaceutical compounds that can fight breast and prostate cancer cells. The synthetic molecules are derived from curcumin, a naturally occurring compound found in the spice turmeric.

Centuries of anecdotal evidence and recent scientific research suggest curcumin has multiple disease-fighting features, including anti-tumor properties. However, when eaten, curcumin is not absorbed well by the body. Instead, most ingested curcumin in food or supplement form remains in the gastrointestinal system and is eliminated before it is able to enter the bloodstream or tissues.

“Newer evidence describes how curcumin interacts with certain proteins to generate anti-cancer activity inside the body. We’re focusing on the pathways that are most involved in cancer and trying to optimize for those properties,” said James Fuchs, assistant professor of medicinal chemistry and pharmacognosy at Ohio State University and principal investigator on the project.
