ries, holds the promise of a major reduction in the time required to produce new preclinical compounds<br />

with enhanced development potential.<br />

VI. Conclusion<br />

The preceding outlines a new drug-discovery paradigm that integrates structure-<strong>based</strong> design, directed<br />

strategies for combinatorial chemical synthesis, and a comprehensive chemi-informatics system for<br />

accumulating and analyzing information regarding chemical properties. Three-dimensional structures<br />

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

compounds. High-throughput automated methods of chemical synthesis produce new classes of lead<br />

compounds and provide for the rapid generation of structure—activity data. Chemical informatics<br />

systems track chemical compounds, store chemical property data, develop predictive SAR models, and<br />

provide a means for intelligently directing the drug-discovery process. By applying this approach not<br />

only to the therapeutic target, but also to molecules involved in absorption, clearance, metabolism, or<br />

toxicology it will be possible to develop predictive models for bioavailability and toxicology. Ultimately<br />

this approach will greatly increase the cost effectiveness and efficiency of drug discovery <strong>by</strong> reducing<br />

the aggregate failure rate for development candidates.<br />
