The Integration of <strong>Structure</strong>-Based <strong>Design</strong> and Directed Combinatorial<br />

Chemistry for New Pharmaceutical Discovery<br />

I. New Challenges For <strong>Drug</strong> Discovery<br />

Page 525<br />

Rapid advances in cell and molecular biology, together with comprehensive genome sequencing efforts,<br />

are providing detailed correlations between specific pathological conditions and discrete molecular<br />

targets. The same tools of recombinant DNA technology that identify key gene targets also provide the<br />

means for target biosynthesis in quantities sufficient for both the high-throughput screening of<br />

compound libraries for leads and the structure-<strong>based</strong> refinement of leads using x-ray crystallography and<br />

NMR spectroscopy.<br />

The rapid expansion in genomics data makes it inevitable that targets will be identified whose functions<br />

are so poorly understood that the most rapid and efficient way to establish their involvement in disease<br />

will be through the development of prototype drugs. New approaches to drug discovery that are able to<br />

integrate many different types of information are needed to seize this opportunity and drive an optimally<br />

efficient discovery process.<br />

In what follows, we describe a practical integration of structure-<strong>based</strong> design and combinatorial<br />

chemistry aimed at enhancing the effectiveness of both approaches. Three-dimensional structures<br />

provide the information required to most efficiently direct the design and optimization of new lead<br />

compounds. Combinatorial chemistry technologies, which are <strong>based</strong> on high-throughput automated<br />

methods of chemical synthesis, produce new classes of lead compounds and permit the rapid generation<br />

of structure—activity relationships<br />
