Chemical biology research in RIKEN NPDepo aimed at agricultural applications.
This review outlines research on chemical biology using mainly microbial metabolites for agricultural applications. We established the RIKEN Natural Products Depository (NPDepo), housing many microbial metabolites, to support academic researchers who focus on drug discovery. We studied methods to stimulate secondary metabolism in microorganisms to collect various microbial products. The switch of secondary metabolism in microorganisms changes depending on the culture conditions. We discovered compounds that activate biosynthetic gene clusters in actinomycetes and filamentous fungi. Using these compounds, we succeeded in inducing the production of active compounds. Two approaches for screening bioactive compounds are described. One is phenotypic screening to explore antifungal compounds assisted by artificial intelligence (AI). AI can distinguish the morphological changes induced by antifungal compounds in filamentous fungi. The other is the chemical array method for detecting interactions between compounds and target proteins. Our chemical biology approach yielded many new compounds as fungicide candidates.
