Extractions: NIGMS Grantee K. Barry Sharpless Wins Nobel Prize for Advances in Mirror-Image Chemistry "Dr. Sharpless' creativity has helped the entire field of chemistry produce extremely useful molecules, including many different therapeutics, that continue to improve the health and enhance the lives of all Americans," said Dr. Ruth L. Kirschstein, acting director of NIH. "This year's Nobel Prizes in Chemistry and Physiology or Medicine both beautifully underscore the value of basic biological research in yielding vital medical advances." The Royal Swedish Academy of Sciences in Stockholm announced the chemistry prize winners this morning. Dr. Sharpless, W.M. Keck Professor of Chemistry at The Scripps Research Institute in La Jolla, California, received half of this year's chemistry award for his work on "chirally catalyzed oxidation reactions." Sharing the other half of the prize for their work on "chirally catalyzed hydrogenation reactions," are Dr. William S. Knowles of St. Louis, Missouri (formerly of the Monsanto Company) and Dr. Ryoji Noyori of Nagoya University, Chikusa, Nagoya, Japan. After more than a decade of trying, in 1980 Dr. Sharpless figured out how to force a chemical reaction to go one-handed. The winning combination turned out to be a mixture of two inexpensive commercial chemicals: a relatively simple titanium compound and either the right or left hand of a chemical called "tartrate."

Extractions: Unlike most academics engaged in basic research, Nobel Laureate K. Barry Sharpless has always been exclusively interested in useful chemistry. Since he regards the oxidation of olefins as the single most versatile, powerful and reliable class of transformations in organic synthesis, Sharpless concentrates on expanding the scope of existing oxidative reactions and discovering new ones. Sharpless is best known for discovering three "name" reactions, general methods for catalytic asymmetric epoxidation, dihydroxlylation, and aminohydroxylation. His Nobel Prize citation says, "many scientists have identified Sharpless's epoxidation [discovered in 1980 with Tsutomu Katsuki] as the most important discovery in the field of synthesis during the past few decades." In 2001 Barry Sharpless received not only the Nobel Prize in Chemistry, but Israel's Wolf Prize, the Benjamin Franklin Medal and the John Scott Medal Award. Also in 2001, Sharpless turned 60, an event celebrated with a three-day symposium during the American Chemical Society's annual meeting; all of the symposium's 33 speakers were former members of Sharpless's research group.

Extractions: The Scripps Research Institute Citation: A Benjamin Franklin Medal of The Franklin Institute in the field of Chemistry is awarded to K. Barry Sharpless for his innovative contributions to the development of broadly useful and commercially viable catalytic oxidation chemistry for the selective production of bioactive molecules with the proper right or left "handedness," which allow the manufacture of safer and more effective drugs and agricultural chemicals. Summary The manufacture of safer and more effective pharmaceuticals and chemicals for a variety of applications in the life sciences demands the ability to selectively synthesize molecules of left or right "handedness." Handedness refers to the existence of pairs of chemical molecules that differ only by being mirror images of each other. The most effective way to steer a chemical reaction toward the formation of only the product of desired handedness is the use of a handed catalyst. While not being consumed in the reaction, the catalyst speeds up the formation of the desired product. In doing so repeatedly, it transfers its "handedness" to many product molecules and thus multiplies its structural information manifold. Professor K. Barry Sharpless has pioneered the discovery of three catalytic reactions that add oxygen atoms to molecules containing a carbon-carbon double bond, to selectively produce chemical compounds with the desired handedness. These processes are used extensively by academic and industrial chemists.

Research Interests, Fahmi Himo Fahmi Himo, Zachary P. Demko, Louis Noodleman, K. barry sharpless, Mechanismsof Tetrazole Formation by Addition of Azide to Nitriles, J. Am. Chem. Soc. http://www.theochem.kth.se/~himo/org.html
Extractions: We have, for instance, studied the formation of tetrazoles and triazoles from addition of azide to nitriles and acetylenes. This work is done together with the lab of Prof. Barry Sharpless (2001 Nobel laureate). The reactions are two examples of the so-called "click chemistry" methodology for chemical synthesis that Sharpless proposed a few years ago [2]. We explained, furthermore, how Zn speeds up the reaction. The most important result here is that Zn, by coordinating the nitrile, activates it towards attack by the azide, lowering the barrier by ca 6 kcal/mol, which agrees very nicely with the rate enhancement of ca 4 orders of magnitude observed experimentally.

Tricking HD Their Own Worst Enemies. K. barry sharpless, Ph.D. WM Keck Professorof Chemistry It works a lot better than we ever anticipated. . http://hdlighthouse.org/see/research/trojanhorse2.htm
Extractions: Just as acetylcholinesterase inhibitors such as Aricept and Huperzine A are being investigated for the treatment of HD, professor Sharpless has a clever easy method to make a more powerful inhibitor. The ablilty of HD to cause disease can be turned against itself. When researchers discover a target for HD treatment, this fast easy method will quickly trick the target into submission. I am reminded of Edna St. Vincent Millay's prophetic sonnet . Jerry 22-Mar-02 "It works a lot better than we ever anticipated." In a first attempt to test a new general strategy for drug discovery, chemists at The Scripps Research Institute (TSRI) and TSRI's Skaggs Institute for Chemical Biology created the most potent blocking agent known against an enzyme implicated in Alzheimer's disease. In the current issue of the journal Angewandte Chemie, 2001 Nobel laureate K. Barry Sharpless, W.M. Keck Professor of Chemistry at TSRI, and colleagues at TSRI and the University of California at San Diego, describe how click chemistry, a modular protocol for organic synthesis that Sharpless developed, was used to make a drug-like molecule that powerfully blocks the neurotransmitter destruction caused by the brain enzyme, acetylcholinesterase. Unlike existing methods, this new drug-discovery strategyclick chemistrymobilizes the target itself, acetylcholinesterase in this case, to play a decisive role and select the final synthetic step. The acetylcholinesterase enzyme actually catalyzed the click reaction that created that enzyme's own inhibitor, and, remarkably, the result is by far the most potent inhibitor ever discovered for this important, widely studied brain enzyme.
