Application of combinatorial chemistry science on modern drug discovery

The science that established combinatorial chemistry as important new discipline in the 1980s and 1990s has re-emerged and infiltrated every sub-discipline within modern drug discovery and has profound impact. The application of combinatorial chemistry science has revolutioned high-throughput screening paradigms, chemical lead optimization, library purification, and post-purification sample handling, as well as in vitro and in vivo drug metabolism and pharmacokinetic assays. Although no longer in the spotlight and heralded as the savior of the drug industry, "combinatorial chemistry" is alive and well; in fact, combinatorial chemistry science is more prevalent and wide-spread than ever before. © 2008 American Chemical Society.
