Nature has been a source of medicinal agents for thousands of years, and an impressive number of modern drugs have been isolated from natural sources, many based on their use in traditional medicine. In the past century, however, an increasing role has been played by microorganisms in the production of antibiotics and other drugs for the treatment of some serious diseases. Advances in the description of the human genome, as well as the genomes of pathogenic microbes and parasites, is permitting the determination of the structures of many proteins associated with disease processes. With the development of new molecular targets based on these proteins, there is an increasing demand for novel molecular diversity for screening. Natural products will play a crucial role in meeting this demand through the continued investigation of world's biodiversity, much of which remains unexplored. With less than 1% of the microbial world currently known, advances in procedures for microbial cultivation and the extraction of nucleic acids from environmental samples from soil and marine habitats, will provide access to a vast untapped reservoir of genetic and metabolic diversity. The same holds true for nucleic acids isolated from symbiotic and endophytic microbes associated with terrestrial and marine macroorganisms. By use of combinatorial chemical and biosynthetic technology, novel natural product leads will be optimized on the basis of their biological activities to yield effective chemotherapeutic and other bioactive agents. The investigation of these resources requires multi-disciplinary, national, and international collaboration in the discovery and development process.
