The microbial screening is an approach for discovering medicines out of microbial metabolites. The natural products (microbial metabolites) are known to possess very unique and complicated structure that could not be imagined. In addition, many of them also have highly potent and selective (specific) biological activities. This report focuses on the feature and present situation of microbial screening in drug discovery field. Firstly, the recent study and development on antitumor antibiotics, duocarmyicins (related compounds) and calicheamicin γ1IIthat indicate extraordinary potent activity, are reviewed. Next, the biochemical and pharmacological study on KS-505a (C 40 tetraterpenoid) produced by Streptomyces argenteolus, a PDE 1 (calcium/calmodulin-dependent phosphodiesterase) isoform selective inhibitor, is presented. The relationship between the microbial screening and recent “chemical biology” or “chemical genetics” approach is also discussed, using for examples, the mode of action of rapamycin and stem cell-based medicine. Finally, the basic strategy in microbial screening (method, target diseases etc.) is described.

The structures of new antitumor antibiotics, Duocarmycin A, C1 and C2, isolated from the culture broth of Streptomyces sp., have been determined on the basis of chemical and physicochemical evidence.
