Automated medicinal chemistry

With the advent of high throughput technologies in biological screening in the 1980s, providing sufficient numbers of small molecules for screening became a bottleneck in the drug discovery process. Combinatorial chemistry was the first attempt by chemists to address this issue. However, since its first applications, combinatorial chemistry has evolved rapidly into diverse fields. This review will focus on the evolution and the current status of what we refer to today as automated medicinal chemistry.

Utilization of NMR-derived fragment leads in drug design

The advent of large-scale NMR-based screening has enabled new strategies for the design of novel, potent inhibitors of therapeutic targets. In particular, fragment-based strategies, in which molecular portions of the final high-affinity ligand are experimentally identified prior to chemical synthesis, have found widespread utility. This chapter will discuss some of the practical considerations for identifying and utilizing these fragment leads in drug design, with special emphasis on some of the lessons learned from more than a decade of industry experience.
