Natural Products and Antifungal Drug Discovery

The need for new antifungal agents continues, fueled by opportunistic infections in immunecompromised patients and by the development of resistance to existing agents. Natural products offer a virtually unlimited source of unique molecules and not only serve as a reservoir for new potential drugs and drug prototypes, but also for probes of fungal biology. In this chapter, whole-cell screening methods targeted for natural products are illustrated, including general microplate-based screening, bioautography, and mode of action studies, including the use of genetically altered fungal strains now available commercially.
