A-39183A is an active component of the A-39183 antibiotic complex produced by aerobic fermentation of Streptomyces NRRL 12049. It has activity against penicillin-resistant S. aureus 3055 and S. faecalis X66 (MICs = 32 and 32 μg/ml, respectively) and a variety of Gram-positive and Gram-negative anaerobic bacteria (MICs = 16-128 μg/ml) in an agar dilution assay.

Dimeric Tetrahydroanthracene Regioisomers and Their Monomeric Precursor Produced by Streptomyces fumigatiscleroticus HDN10255
J Nat Prod 2020 Sep 25;83(9):2797-2802.PMID:32880456DOI:10.1021/acs.jnatprod.0c00805
Four new tetrahydroanthracene derivatives (1, 3-5) and a known antibiotic, A-39183A (2), were discovered from the marine-sponge-derived actinomycete Streptomyces fumigatiscleroticus HDN10255. Their structures including absolute configurations were elucidated based upon MS and NMR spectroscopic data, ECD calculations, and biogenetic considerations. Compounds 2 and 4 showed considerable cytotoxicity with the best IC50 value of 1.8 μM against HeLa cells.
