Over the last decade, a wealth of new technologies and conceptual approaches for bioactivity screening have emerged.
A. Antibiotic discovery is an example where there is particular concern over the ability of top-down natural products investigations to yield fundamentally new classes of agents (9, 10).Almost all of the early antibiotic scaffolds were derived from natural sources, and there have been no new clinically approved natural product-based antibiotics discovered for over 30 y (1, 11).
