Soybeans Release Anti-cancer Agent

Friday, 11 May 2012 11:14 PM

Soybeans soaking in warm water releases a potent cancer-fighting substance and the technique could become a new "green" way to produce it for use in treating patients, a new study has found.
The research, published in the American Chemical Society Journal of Agricultural and Food Chemistry, could lead to a new and simpler way to produce the cancer-fighting agent now manufactured in a complicated and time-consuming industrial process, scientists said.
Hari B. Krishnan and colleagues said the substance derived from soybeans -- Bowman-Birk Protease Inhibitor (BBI) – has been found to prevent certain forms of cancer in clinical trials. But the current method of extracting BBI from soybeans is time-consuming and involves harsh chemicals.
In attempting to find a simpler, more eco-friendly way of obtaining BBI, Krishnan’s team found soybean seeds incubated in water at 122 degrees Fahrenheit naturally release large amounts of BBI that can easily be harvested from the water.
The protein appeared to be active, with tests showing that it stopped breast cancer cells from growing in a laboratory dish.
"The abundance of BBI in soybean seed exudates by incubating the seeds in warm water provides a simple and alternative method to isolate this low molecular weight protein," the researchers said.
The study was funded by the Agricultural Research Service of the U.S. Department of Agriculture.
