An integrated technology for drug discovery combines the<br />

precision of structure-<strong>based</strong> design with the parallelism of<br />

combinatorial synthesis. Chemi-informatics systems track<br />

and integrate all data emerging from the discovery cycle.<br />

(SAR). Chemi-informatics plays a key role in this integration <strong>by</strong> assuring that properties important in<br />

drug development are both factored into compound design and cumulatively tracked throughout the<br />

discovery process (Figure 1). The product of this approach is a permanently useful set of drug-design<br />

parameters. The integration of these technologies promises to produce an increase in the efficiency of<br />

drug discovery and may ultimately offer a means for reducing the aggregate failure rate of compounds<br />

selected for development. One paradigm for achieving the integration of these technologies is described<br />

below.<br />

II. <strong>Structure</strong>-Based <strong>Design</strong><br />

<strong>Structure</strong>-<strong>based</strong> drug design has become a highly developed technology that is in active use in most<br />

major pharmaceutical companies. <strong>Structure</strong>-<strong>based</strong> design is an iterative process in which lead<br />

compounds identified <strong>by</strong> screening, de novo design, or mechanism-<strong>based</strong> features are systematically<br />

elaborated to improve potency and specificity [1,2]. The process involves successive rounds of structure<br />

determination of lead—target complexes, design of lead modifications using molecular modeling tools,<br />

synthesis of new drug leads, and measurement of the chemical and biological properties of the modified<br />

leads using screens for target<br />
