The witch doctors' gift: Potential new drugs from a cup of tea
Date:9/29/2011

ives."

"New Drugs From a Cup of Tea" features the research of David Craik, Ph.D., winner of the 2011 ACS Ralph F. Hirschmann Award in Peptide Chemistry. Peptides are chains of amino acids, the building blocks of proteins. Craik is a professor at the University of Queensland in Australia, and the video describes his research, which promises to turn kalata-like proteins, called cyclotides, into new drugs for treating health problems, such as antibiotic-resistant bacteria and even AIDS, which affect millions of people worldwide. Proteins already number among the world's most important medicines. Insulin, for instance, is a protein. Many other proteins could become life-saving medicines. But there's a problem with proteins and smaller chunks of proteins called peptides. They cannot be taken by mouth because the body breaks them apart during digestion, just like the protein in meat or soy. The video explains how cyclotides have a strong internal architecture that keeps them active when taken by mouth.

Prized Science's 2011 launch episode is a video featuring the research of Nobel Laureate Ahmed Zewail, Ph.D., winner of the ACS 2011 Priestley Medal, the society's highest honor. Zewail is the Linus Pauling Chair professor of chemistry and professor of physics at the California Institute of Technology and recipient of the 1999 Nobel Prize in Chemistry. The video, Designing the World's Fastest Camera, highlights Zewail's work on imaging chemical and biological events that happen very quickly in a femtosecond, which is a millionth of a billionth of a second. His latest work involves revolutionary new technology that enables scientists to visualize objects, not in three dimensions, but in four dimensions. In doing so, it promises to have sweeping applications in medicine, electronics and biological research.
