Amycolachromones A-F, Isolated from a Streptomycin-Resistant Strain of the Deep-Sea Marine Actinomycete Amycolatopsis sp. WP1

Mar Drugs. 2022 Feb 24;20(3):162. doi: 10.3390/md20030162.

Abstract

In this study, a detailed chemical investigation of a streptomycin-resistant strain of the deep-sea marine, actinomycete Amycolatopsis sp. WP1, yielded six novel amycolachromones A-F (1-6), together with five known analogues (7-11). Amycolachromones A-B (1-2) possessed unique dimer skeletons. The structures and relative configurations of compounds 1-11 were elucidated by extensive spectroscopic data analyses combined with X-ray crystal diffraction analysis. Plausible biogenetic pathways of amycolachromones A-F were also proposed.

Keywords: isolation; marine actinomycetes; secondary metabolites.
