Ochromycinone ((Rac)-STA-21) is a natural antibiotic and a STAT3 inhibitor. Ochromycinone can inhibits STAT3 DNA binding activity, STAT3 dimerization. Ochromycinone has anticancer and antimicrobial activity[1][2].
STA-21 inhibits STAT3 DNA binding activity, STAT3 dimerization, and STAT3-dependent luciferase activity. Moreover, STA-21 reduces the survival of breast carcinoma cells with constitutive STAT3 signaling but has minimal effect on the cells in which constitutive STAT3 signaling is absent[2].

11-Hydroxy-3,3-dimethyl-7,12-dioxo-3,4,6,6a,7,12,12a,12b-octahydrobenz[a]anthracen-1-yl acetate
Acta Crystallogr C 2003 Aug;59(Pt 8):o431-2.PMID:12909769DOI:10.1107/s0108270103013374.
The Diels-Alder reaction between 5-hydroxy-1,4-naphthoquinone and 5,5-dimethyl-3-vinyl-1,2-cyclohexadienyl acetate by endo addition gives the title compound, C(22)H(22)O(5), in 68% yield. This racemic diastereoisomer has the opposite regiochemistry to Ochromycinone analogues produced previously and may allow access to a new type of anticancer-active saquayamycin analogue.
Angucyclinones from an Indonesian Streptomyces sp
J Nat Prod 2008 Jan;71(1):61-5.PMID:18081255DOI:10.1021/np0704102.
Six new angucyclinone polyketides named panglimycins A-F were isolated together with the three known metabolites (+)-fujianmycin A, (+)-ochromycinone, and emycin C from the bioassay-guided fractionation of the extract of the Indonesian Streptomyces strain ICBB8230. The new compounds are highly oxygenated angucyclinones that appear to be biosynthetically derived from Ochromycinone or fujianmycin. Their structures were determined by X-ray crystal analysis, interpretation of 1D- and 2D-NMR spectra, and comparison of the data with those of structurally related known natural products. Despite structural similarities to angucyclinones with antibiotic activities, the panglimycins did not exhibit any growth inhibition when tested against several bacteria and fungi.
Fujianmycin C, A bioactive angucyclinone from a marine derived Streptomyces sp. B6219
Nat Prod Commun 2010 Dec;5(12):1917-20.PMID:21299120doi
From a marine-derived streptomycete, a new bioactive angucyclinone, fujianmycin C (1), has been isolated along with five known, metabolites fujianmycins A (2) and B (3), Ochromycinone (4), Ochromycinone methyl ether (5), and tetrangulol methyl ether (6). The structure elucidation of fujianmycin C (1) was performed by detailed analysis of data such as 1H, 13C, 1H, 1H COSY, HSQC, HMBC and NOESY spectra. Fujianmycin C (1) exhibited antibacterial activity against Streptomyces viridochromogenes (Tü57).
Purification and identification of bioactive angucyclinones from Streptomyces matensis BG5, isolated from the rhizosphere of Rosa indica L
Prep Biochem Biotechnol 2013;43(1):22-32.PMID:23215652DOI:10.1080/10826068.2012.693897.
A newly isolated strain Streptomyces sp. BG5 was investigated for the production of bioactive compounds. The strain exhibited broad-spectrum activity against an array of nine test organisms including gram-positive bacteria, gram-negative bacteria, and fungal and microalgal pathogens, along with a moderate cytotoxic response (28.9% mortality) in a microwell cytotoxicity assay against the brine shrimp Artimia salina. The morphological, physiological, and biochemical characterization of the Streptomyces sp. BG5 strongly suggested it to be a member of the genus Streptomyces. The nucleotide sequence of 16S rRNA gene (1433 pb) of the Streptomyces sp. BG5 (Gene bank accession number EU301836) exhibited high similarity (98%) with Streptomyces matensis. The large-scale fermentation of Streptomyces sp. BG5 and subsequent extraction, isolation, and purification of the crude extract afforded three pure compounds. The structures of these compounds were identified as Ochromycinone (1a), emycin D (2), and 1-acetyl-β-carbolin (3), based on nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry, and by comparison with reference data from the literature.
