U.VA. CHEMIST SIDNEY M. HECHT IS NAMED VIRGINIA'S OUTSTANDING SCIENTIST CHARLOTTESVILLE, Va., Feb. 29 -- Sidney M. Hecht, a University of Virginia chemistry professor whose research on cancer-fighting drugs may help improve their effectiveness, was today named Virginia's Outstanding Scientist of 1996 by the Commonwealth and the Science Museum of Virginia. Hecht was honored by the General Assembly at the State Capitol in Richmond at noon today, along with three others in the fields of science and industry. They are retired Newport News executive Shin-Ichiro Nagashima, who was named Virginia's Outstanding Industrialist; and Virginia Commonwealth University professor of microbiology and immunology S. Gaylen Bradley, and Del. Joe T. May, a Northern Virginian entrepreneur, both of whom received Life Achievement Awards. Hecht was cited for his significant contributions to the search for more effective cancer therapies and, in particular, for his study of bleomycin, a potent anti-tumor drug derived from a soil-dwelling microorganism. Like many cancer drugs, bleomycin works by disrupting the DNA within a cell's nucleus. This halts cell division and kills the cell. However, bleomycin and other anti-cancer drugs kill any growing cell and so both cancerous and normal cells may be targeted for destruction. Hecht and his colleagues are seeking ways to improve the specificity of bleomycin, so that it attacks only cancerous cells. In a recent finding, Hecht, who is the John W. Mallet Professor of Chemistry and professor of biology, observed that bleomycin cuts up cellular RNA as well as DNA. This is significant because RNA, unlike DNA, is present outside of the cell's nucleus and thus is more vulnerable to drug attack. Hecht also recently reported that bleomycin cuts RNA at fewer sites than DNA. The relative rarity of these sites might permit chemists to design drugs that would zero in on these points alone, increasing the likelihood that tumor cells alone would be destroyed. This latest work was made possible by an earlier achievement of Hecht's. In 1982, he accomplished the complete synthesis of bleomycin. Prior to this breakthrough, bleomycin was available only in minuscule quantities through fermentation of the microorganism Streptomyces verticillus. Larger amounts of bleomycin enabled the scientists both to analyze the actions of bleomycin itself and to form analogs, or variations, of the drug that could have better anti-cancer activity. ### February 28, 1996 REPORTERS AND EDITORS: For interviews about his work with bleomycin and other anti-cancer agents, including one awaiting FDA approval for use against ovarian cancer, Hecht may be reached at (804) 924-3344.
