■ In vivo animal model results for 30,000 compounds ■ 2-D and 3-D chemical structures for more than 200,000 compounds ■ Molecular target data, including characterizations for at least 1200 targets, plus data from multiple cDNA microarray projects In addition to browsing DTP’s databases and downloading data, researchers can request individual samples or sets of compounds on 96-well plates for research, or they can submit their own compounds for consideration for screening via DTP’s online submission form. Once a compound is submitted for screening, researchers can follow its progress and retrieve data using a secure Web interface. The NCI has collected information on almost half a million chemical structures in the past 40 years. DTP has made this information accessible and useful for investigators through its 3-D database, a collection of three-dimensional structures for more than 400,000 drugs. Investigators use the 3-D database, which is maintained by DTP, to screen compounds for anticancer therapeutic activity. Also available on DTP’s Website are 127,000 connection tables for anticancer agents. A connection table is a convenient way of depicting molecular structures without relying on drawn chemical structures. As unique lists of atoms and their connections, the connection tables can be indexed and stored in computer databases where they can be used for patent searches, toxicology studies, and precursor searching, for example.

National Cancer Institute. commercial establishments at no charge. This facility obtains new materials by donation or at reduced cost by negotiating with companies and investors. To date, the Biological Resources Branch Preclinical Repository has distributed more than 40,000 samples, and the estimated value of materials shipped to investigators is about $100,000 per year. Radiolabeled Materials Repository http://dtp.nci.nih.gov/docs/misc/ available_samples/radiolbllist2.html For researchers who hold a valid radioactive materials license, there are roughly 90 radiolabeled drugs available from DTP’s Radiolabeled Materials Repository. Radiolabeled compounds are instrumental in noninvasive studies of biodistribution and in target pharmacokinetics of therapeutics. In early trials, 11 of 16 patients with hairy cell leukemia had complete remissions after receiving BL22. 110 ■ P R O G R A M A C C O M P L I S H M E N T S 2 0 0 6 Drug Formulation and Synthesis DTP’s Pharmaceutical Resources Branch bears the responsibility of acquiring bulk materials for formulation and synthesis, formulating drugs and testing them, clinical dosage-form production, and stability testing of clinical dosage forms. This branch provides clinical researchers, both academic and institutional, with topquality drugs for clinical trials and formulates drug compounds that are candidates for the Drug Development Group or the RAID program. Drug Production: Biopharmaceutical Development Program http://wwwbdp.ncifcrf.gov/ DTP’s Biological Resources Branch oversees the Biopharmaceutical Development Program (BDP), which provides biopharmaceutical development expertise and production capability to all NIH-supported investigators. The BDP produces a variety of clinical-grade biological agents from bacterial, yeast, and mammalian cells; natural products from various organisms; and DNA, RNA, and viral materials under current Good Manufacturing Practices for phase I/II human clinical trials or advanced preclinical animal testing. Researchers have attempted to design cancer therapies to avoid toxicities associated with standard chemotherapeutic agents. BL22, one such targeted treatment, originated in an intramural NCI laboratory and was developed through DTP’s biologicals production facility.
