The declining trends in microbial metabolite and natural products research and the refocusing of this research area are
discussed. Renewing natural products research requires inexhaustible natural resources, as well as new genetic techniques and
microbial sources, including endophytic microbes. The numbers of known bioactive metabolites are summarized according to
their microbiological origin, biological activities and chemical structures. Synthetic and natural product-based libraries are also
compared. Importantly, the wide range of microbial metabolite bioactivities, future trends and the importance of prioritizing
natural products over synthetic compounds are emphasized.
