NCI Basic Research into HIV Structure Pays Off in AIDS Drug Development
BETHESDA, Md--NCI research from the 1980s, in which scientists used crystallography to study the structure of the human immunodeficiency virus (HIV), paved the way for development of the current crop of HIV-specific protease inhibitors (see " Early Combination Treatment May Provide HIV Control" for a report on clinical trials of protease inhibitors).

Data from crystallization studies were used to develop 3-dimensionalmodels of the enzyme. Researchers were then able to determinethe shape a protease inhibitor must have to "fit" intothe enzyme's active site and inhibit its function.
The coordinates for the 3-dimensional image were deposited inthe Brook-haven National Laboratory database, making the structureavailable to pharmaceutical companies, who then put their drugdesign teams to work to develop novel inhibitors.
George VandeWoude, PhD, special advisor to the director of NCI'sDivision of Basic Sciences, said that the achievement "emphasizesthat basic research is worth the effort."
