Secondary metabolites of marine-derived actinomycete microbes and their bioactivities

Actinomycete microbes are the most important and largest class of microbes for medicinal usage up to date. Marine-derived actinomycete microbes possess metabolic capabilities different from those of terrestrial actinomycete microbes, which were obtained during their evolution in the marine environment, resulting in the distinct peculiarity and wide diversity of their metabolites in chemical structure and biological activity. Numerous natural products with novel structure and distinct biological activity have been discovered from the secondary metabolites of marine-derived actinomycete microbes. These bioactive compounds provided much valuable leading compounds for new drug development, and some of them even have been being in a stage of product development. Current studies on the bioactive metabolites of marine-derived actinomycete microbes are yet very hot and important in the marine-derived microbial natural products research field. Here, we review briefly the research advances achieved recently in the studies on the secondary metabolites of marine-derived actinomycete microbes and their biological activities in terms of the structural types of the metabolites.
