Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A fundamental component for success in drug discovery is the ability to assemble and screen compounds that encompass a broad swath of biologically relevant chemical‐diversity space. Achieving this goal in a natural‐products‐based setting requires access to a wide range of biologically diverse specimens. For this reason, we introduced a crowdsourcing program in which citizen scientists furnish soil samples from which new microbial isolates are procured. Illustrating the strength of this approach, we obtained a unique fungal metabolite, maximiscin, from a crowdsourced Alaskan soil sample. Maximiscin, which exhibits a putative combination of polyketide synthase (PKS), non‐ribosomal peptide synthetase (NRPS), and shikimate pathway components, was identified as an inhibitor of UACC‐62 melanoma cells (LC50=0.93 μ<sc>M</sc>). The metabolite also exhibited efficacy in a xenograft mouse model. These results underscore the value of building cooperative relationships between research teams and citizen scientists to enrich drug discovery efforts.</p> </abstract>
