Three new secondary metabolites, amycofuran (1), amycocyclopiazonic acid (2), and amycolactam (3), were isolated from the sponge-associated rare actinomycete Amycolatopsis sp. Based on combined spectroscopic analyses, the structures of 1–3 were determined to be a new benzofuran glycoside and new indole alkaloids related to cyclopiazonic acids, a class that has previously only been reported in fungi. The absolute configurations of 1 and 3 were deduced by ECD calculations, whereas that of 2 was…

Actinomadurol, an Antibacterial Norditerpenoid from a Rare Actinomycete, Actinomadura sp. KC 191.
TLDR
A new secondary metabolite was isolated along with the known compound JBIR-65 from a rare actinomycete, Actinomadura strain KC 191, and exhibited potent antibacterial activity against pathogenic strains, such as Staphylococcus aureus, Kocuria rhizophila, and Proteus hauseri.
Suncheonosides A-D, Benzothioate Glycosides from a Marine-Derived Streptomyces sp.
TLDR
Suncheonosides A, B, and D promoted adiponectin production in a concentration-dependent manner during adipogenesis in human mesenchymal stem cells, suggesting antidiabetic potential.
Salternamide E from a Saltern-derived Marine Actinomycete Streptomyces sp.
TLDR
Comprehensive chemical analysis of extracts and fractions of marine actinomycete strains led to the discovery of a new minor secondary metabolite, salternamide E, from a saltern-derived halophilic Streptomyces strain, displaying weak cytotoxicity against various human carcinoma cell lines.
Secondary Metabolites of the Genus Amycolatopsis: Structures, Bioactivities and Biosynthesis
TLDR
The objective in this review is to summarize the chemical structures and biological activities of secondary metabolites from the genus Amycolatopsis, a rare actinomycete genus with the potential to produce antibiotics with a total of 159 compounds derived from 8 known and 18 unidentified species.
Pentacyclic antibiotics from a tidal mud flat-derived actinomycete.
TLDR
