Daffodil Compound Used to Target Brain Cancer

"We hope narciclasine could be given to brain cancer patients in addition to conventional therapies.” The study's findings were published in the November 2010 print issue of the FASEB Journal.

To make this discovery, Dr. Kiss and colleagues employed computer-assisted techniques to identify targets for narciclasine in cancer cells. The strongest potential candidate to emerge was the eEF1A elongation factor. Researchers then grafted human melanoma brain metastatic cells into the brains of genetically altered mice. The study's findings revealed that the injected mice survived significantly longer when treated with narciclasine than those mice left untreated. The researchers believe that narciclasine selectively inhibits the proliferation of very aggressive cancer cells, while avoiding adverse effects on normal cells. Narciclasine could be used in the near future to combat brain cancers, including gliomas, and metastases such as melanoma brain metastases.

"Scientists have been digging in odd corners to find effective treatments for brain cancer for decades, and now they've found one in daffodils,” said Gerald Weissmann, M.D., editor-in-chief of the FASEB Journal, "It doesn't mean that you should eat daisies or daffodils for what ails you, but that modern medicinal chemistry can pluck new chemicals from stuff that grows in the garden. This is a good one.”
