In the following decades, the drug development of microbial natural products has always been a hot spot and frontier in the field of new drug research and development. The secondary metabolites produced by microorganisms have a variety of biological activities, which can be used as anticancer drugs, antiparasitic drugs, anti-inflammatory drugs, immunosuppressants and so on, and play an important role in human health.
