Discovery of phosphonic acid natural products by mining the genomes of 10,000 actinomycetes

Abstract

Significance The discovery of natural products, an important source of human medicines, is critical for the development of new therapeutics against health threats, including cancer and multidrug-resistant pathogens. Yet, in recent years, industrial development of pharmaceuticals from natural products has been stymied due to a variety of reasons, including the repeated discovery of previously known compounds. Here, we demonstrate large-scale genomics as one potential solution to this problem by mining a collection of 10,000 actinomycetes for novel phosphonic acids, an important class of natural products with antimicrobial, antiviral, antimalarial, and herbicidal activities. The framework described here provides a foundation for rapid, large-scale discovery of other classes of natural products and their use as lead compounds in the pharmaceutical industry.
