Abstract
Bitetracenomycin A (1) and its diastereomers [(±)-bitetracenomycin B, (±)-2] were discovered from the cultures of Streptomyces sp. HDN154193. Compounds 1 and (±)-2 were the first tetracenomycin dimers obtained from a natural source with sp3 methine protons at the bridge positions (C-12/12'), which also exhibited broad-spectrum antibacterial activity. The racemate (±)-2 was semisynthesized and separated into enantiomers (+)-2 and (-)-2, and the absolute configurations were determined by specific rotation and ECD data. These metabolites exhibited potent antibacterial activity especially against drug-resistant strains (MRSA and MRCNS) with MIC values ranging from 1.0 to 1.9 μg/mL.

Abstract
Six new tetracenomycin congeners, saccharothrixones E⁻I (1⁻5) and 13-de-O-methyltetracenomycin X (6), were isolated from the rare marine-derived actinomycete Saccharothrix sp. 10-10. Their structures were elucidated by spectroscopic analysis and time-dependent density functional theory (TDDFT)-electronic circular dichroism (ECD) calculations. Saccharothrixones G (3) and H (4) are the first examples of tetracenomycins featuring a novel ring-A-cleaved chromophore. Saccharothrixone I (5) was determined to be a seco-tetracenomycin derivative with ring-B cleavage. The new structural characteristics, highlighted by different oxidations at C-5 and cleavages in rings A and B, enrich the structural diversity of tetracenomycins and provide evidence for tetracenomycin biosynthesis. Analysis of the structure⁻activity relationship of these compounds confirmed the importance of the planarity of the naphthacenequinone chromophore and the methylation of the polar carboxy groups for tetracenomycin cytotoxicity.

Abstract
The crude extracts of the fermentation broth from a marine sediment-derived actinomycete strain, Saccharothrix sp. 10-10, showed significant antibacterial activities against drug-resistant pathogens. A genome-mining PCR-based experiment targeting the genes encoding key enzymes involved in the biosynthesis of secondary metabolites indicated that the strain 10-10 showed the potential to produce tetracenomycin-like compounds. Further chemical investigation of the cultures of this strain led to the identification of two antibiotics, including a tetracenomycin (Tcm) analogs, Tcm X (1), and a tomaymycin derivative, oxotomaymycin (2). Their structures were identified by spectroscopic data analysis, including UV, 1D-NMR, 2D-NMR and MS spectra. Tcm X (1) showed moderate antibacterial activities against a number of drug-resistant pathogens, including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE) pathogens, with the MIC values in the range of 32-64 microg x mL(-1). In addition, 1 also displayed significant cytotoxic activities against human cancer cell lines, including HL60 (leukemia), HepG2 (liver), and MCF-7 (breast) with the IC 50 values of 5.1, 9.7 and 18.0 micromol x L(-1), respectively. Guided by the PCR-based gene sequence analysis, Tcm X (1) and oxotomaymycin (2) were identified from the genus of Saccharothrix and their 13C NMR data were correctly assigned on the basis of 2D NMR spectroscopic data analysis for the first time.

Abstract
We isolated a bioactive streptomycete from marine sediment samples collected at Bay of Bengal, India, during our systematic study of marine actinobacteria. The taxonomic studies indicated that the isolate is related to Strepomyces corchorusii. However, it differed in certain aspects, and, hence, was designated as S. corchorusii AUBN(1)/7. A solvent extraction followed by a chromatographic purification helped obtain from the isolate two cytotoxic compounds, which were identified as resistomycin, a quinone-related antibiotic, and tetracenomycin D, an anthraquinone antibiotic, on the basis of spectral data of pure compounds. They demonstrated in vitro a potent cytotoxic activity against cell lines HMO2 (gastric adenocarcinoma) and HepG2 (hepatic carcinoma) and also exhibited weak antibacterial activities against Gram-positive and Gram-negative bacteria.

Abstract
Sugar biosynthesis cassette genes have been used to construct plasmids directing the biosynthesis of branched-chain deoxysugars: pFL942 (NDP-L-mycarose), pFL947 (NDP-4-deacetyl-L-chromose B), and pFL946/pFL954 (NDP-2,3,4-tridemethyl-L-nogalose). Expression of pFL942 and pFL947 in S. lividans 16F4, which harbors genes for elloramycinone biosynthesis and the flexible ElmGT glycosyltransferase of the elloramycin biosynthetic pathway, led to the formation of two compounds: 8-alpha-L-mycarosyl-elloramycinone and 8-demethyl-8-(4-deacetyl)-alpha-L-chromosyl-tetracenomycin C, respectively. Expression of pFL946 or pFL954 failed to produce detectable amounts of a novel glycosylated tetracenomycin derivative. Formation of these two compounds represents examples of the sugar cosubstrate flexibility of the ElmGT glycosyltransferase. The use of these cassette plasmids also provided insights into the substrate flexibility of deoxysugar biosynthesis enzymes as the C-methyltransferases EryBIII and MtmC, the epimerases OleL and EryBVII, and the 4-ketoreductases EryBIV and OleU.

Abstract
Chemical analysis of an Australian Streptomyces species yielded a range of known anthracyclines and biosynthetically related metabolites, including daunomycin (1), epsilon-rhodomycinone (2), 11-hydroxyauramycinone (3), 11-hydroxysulfurmycinone (4), aklavinone (5), bisanhydro-gamma-rhodomycinone (6), and the anthraquinone 7, as well as the hitherto unreported blanchaquinone (8). The structure assigned to 8 was secured by detailed spectroscopic analysis and correlation to known analogues, such as the anthraquinone 7. This account also represents the first natural occurrence of 3, 4, and 7 and the first spectroscopic characterization of 11-hydroxysulfurmycinone (4).

Abstract
Aqueous two-phase systems (ATPS) were applied for extraction of small molecules (polycetides) - retamycin, an anthracyclin, and two red pigments, rubropunctamin and monascorubramin - from the whole culture media of Streptomyces olindensis and Monascus purpureus. ATPS allows, in one step, the separation of the small hydrophobic molecules in the PEG rich phase, from the filamentous microorganisms, which remains in the salt phase. Through experimental designs, the main variables and their levels were defined, as follows: for retamycin extraction, PEG 6000 (10%, w/w), phosphate at 20% (w/w) and pH 6.0 led to the higher partition coefficient, K(r) = 8.2, and yield = 91.3%; for red pigments, the statistical analysis indicate PEG 6000 (20%, w/w) and phosphate at 15% (w/w), for a high partition coefficient, (K(pig) = 113 and 150).

Abstract
During the screening of microbial fermentation extracts for their ability to inhibit the binding of 125I-peptid YY (PYY) to the neuropeptide Y (NPY) receptor using the scintillation proximity assay (SPA), BMS-192548 was isolated from the extract of Aspergillus niger WB2346 by bioassay-guided fractionation. BMS-192548 showed the inhibitory activity against 125I-PYY binding to SK-N-MC and SMS-KAN cells, which express NPY1 and NPY2 receptors, respectively, with IC50 values of 24 microM in Y1 and 27 microM in Y2 receptor binding. BMS-192548 demonstrated weak cytotoxicity against murine tumor cell line M-109 with an IC50 value of 240 microM.

Abstract
A new angucyclinone, named balmoralmycin (1), was isolated as an inhibitor of protein kinase C-alpha (PKC-alpha) from the Streptomyces strain P6417. Chemical screening of extracts of the same strain resulted in the detection of two decaketides with unusual structural features (2 and 3). Both compounds belong to a recently described structural class of secondary metabolites which arises from engineered biosynthesis of a recombinant Streptomyces strain. The isolation of compounds of this class from a wild-type strain has never been reported before.

Abstract
Nucleotide sequence analysis of the tcmG gene has suggested that the TcmG protein is responsible for the triple-hydroxylation of tetracenomycin (Tcm) A2 to Tcm C in Streptomyces glaucescens (Decker, H., Motamedi, H., and Hutchinson, C.R. (1993) J. Bacteriol. 175, 3876-3886). The heterologous expression of the tcmG gene in Streptomyces lividans and the purification and characterization of TcmG protein, which we have named Tcm A2 oxygenase, are described here. NH2-terminal amino acid analysis of the purified enzyme led to the revision of the translational start site of tcmG to a TTG, 33 base pairs downstream of the GTG site assigned initially on the basis of nucleotide sequence analysis. Tcm A2 oxygenase is a monomeric protein in solution and contains 1 mol of non-covalently bound FAD; the apoenzyme can be partially reconstituted in vitro by addition of FAD. Tcm A2 oxygenase exhibits an optimal pH of 9.0-9.5 and prefers NADPH over NADH as an electron donor. The apparent K'm of the enzyme for Tcm A2, NADH, and NADPH are 1.81 +/- 0.38, 260 +/- 19, and 82.1 +/- 17 microM, respectively, and the apparent V'max for the reaction is 14.7 +/- 1.1 nmol Tcm C/min.mg. Purification and characterization of Tcm A2 oxygenase provide direct evidence to support the notion that the angular hydroxy groups of naphthacenequinones like Tcm C are introduced from 18O2 via a mono- or dioxygenase process.

Abstract
This report describes the fermentation, isolation, and structural elucidation of tetracenomycin (Tcm) F2 [2], a metabolite produced by a blocked mutant strain WMH1092 of the Tcm C [1] producer Streptomyces glaucescens and by the recombinant strain S. glaucescens WMH1077 (pWHM722). Elucidation of the Tcm F2 structure shows that 2 is the earliest intermediate identified to date in the biosynthesis of 1. This is supported by the fact that 2 is very efficiently biotransformed to 1 by the S. glaucescens WMH1068 strain and is enzymatically converted to Tcm F1 [3] and to Tcm D3 [4], a known intermediate of Tcm C biosynthesis.

The structure of 5838-DNI was shown to be 1,4,4a,5,12,12a-hexahydro-4,4a,11,12a-tetrahydroxy-3,8-dimethoxy-9- methoxycarbonyl-10-methyl-1,5,12-trioxo naphthacene. Although similar in structure to tetracenomycin C, which is an antibiotic against Gram-positive bacteria, 5838-DNI has different antibacterial activity. 5838-DNI was distinguished from 5923-DNI, a previously reported DNase II inhibitor, in inhibitory activity against each enzyme. 5838-DNI showed dependency of inhibition on pH and temperature, and inhibited phosphodiesterase I in a competitive manner. These data suggest that 5838-DNI is the first reported example of an inhibitor of microbial origin which is able to inhibit DNase II and phosphodiesterase I.

Abstract
Tetracenomycins B3 and D3, besides tetracenomycin D (D1), were produced by a blocked mutant of the elloramycin producer Streptomyces olivaceus TU 2353. The compounds were isolated as red powders, and their structures were elucidated by comparing their physicochemical data with those of the known tetracenomycins A2, B1, B2, D and E. Tetracenomycin B3 (2), the main compound, and tetracenomycin D (3) were antibiotically inactive against Gram-positive and Gram-negative bacteria, whereas tetracenomycin D3 (1) showed a moderate activity against Bacillus subtilis and Arthrobacter aurescens. Tetracenomycin B3 (2) is the key intermediate where the biosynthesis of the elloramycins branches off from the line leading to tetracenomycin C (5) as the final product of the tetracenomycin biosynthesis branch.

Abstract
Five metabolites were isolated from fermentations of a mutant strain S 383 of Streptomyces galilaeus. Components S 383-O and S 383-A were identified as known derivatives of anthraquinone and naphthacenequinone, respectively, previously isolated from cultures of other blocked mutants of S. galilaeus strains. Component S 383-X was identical with 7-deoxyaklavinone. Compound S 383-Y (aklaviketone) was found to be a new metabolite. Its chemical structure has been determined by physico-chemical methods including mass spectrometry and NMR spectral studies. The compound (7-dehydro-7-deoxy-7-oxoaklavinone) is most likely the first cyclization product along the metabolic chain possessing the tetracyclic carbon skeleton of anthracyclinones. A proposed pathway is discussed.

Abstract
Arugomycin (AGM) is a new anthracycline antibiotic produced by strain No. 1098-AV2 which was identified as Streptomyces violaceochromogenes. AGM was isolated by solvent extraction, silicic acid chromatography and Sephadex LH-20 column chromatography. Acid treatment of AGM gave the chromophore, named arugorol, which was identified as 4'-epi-nogalarol, and sugar moieties. AGM inhibited the growth of Gram-positive bacteria and showed antitumor activity against sarcoma S-180 and Ehrlich ascites tumors.

Abstract
The structures of cervinomycins A1 (1) and A2 (2), a potent anti-anaerobic and anti-mycoplasmal antibiotic were investigated by means of recent NMR techniques of O-methyl ether (3) and C,O-dimethyl ether (4) obtained by methylation of 2 with CH3I in the presence of Ag2O. The antibiotic 2 posesses a polycyclic structure involving a xanthone skeleton. The structure of 1 was confirmed to be a hydroquinone of 2 from the evidences that oxidation of 1 with Ag2O and acetylation of 1 with (CH3CO)2O in pyridine afforded quantitatively 2 and triacetylcervinomycin A1 (7), respectively.

Abstract
A culture of Streptomyces sp., producing an antibiotic named galtamycin was isolated from a soil sample collected in the Gorno-Altai Autonomous Region. The antibiotic belongs to anthracyclines. Biosynthesis, isolation, physico-chemical and biological properties of the antibiotic are described. The studies showed that galtamycin consisting of a chromophore and three unidentified sugars is a new compound differing from the known anthracyclines except trypanomycin by the absence of the UV absorption maximum at 230-240 nm. Galtamycin differs from trypanomycin by the molecular weight of the chromophore. Galtamycin showed low antitumor activity and was inactive against grampositive and gramnegative organisms and fungi.

Abstract
The isolation and identification of several anthracyclinones (designated as G44-K4/5, G44-G1, G44-G2) and anthracyclines (G44-A, B, C, D, E, F, G) produced by the mutant strain IMET JA 3933/G44 of the daunomycin-producing Streptomyces griseus strain IMET JA 3933 are described. G44-K4/5 was found to be identical with 7,11-dideoxy-13-dihydrodaunomycinone previously isolated from a mutant strain of Streptomyces coeruleorubidus. Compound G44-G1 was identified as 11-deoxydaunomycinone, the aglycone of the antibiotic 11-deoxydaunomycin. G44-G2 was found to be a stereoisomer of G44-G1. The NMR and CD spectral data suggest strongly that the compound is 7-epi-11-deoxydaunomycinone. Of the 7 isolated G44-glycosides only the major component G44-B could be identified. Comparison with an authentic sample revealed that this compound is 11-deoxydaunomycin which had previously been isolated from cultures of Streptomyces peucetius var. aureus and Micromonospora peucetica. As reported for S. coeruleorubidus, S. peucetius var. aureus, and Micromonospora peucetica the 11-deoxydaunomycinone derivatives described in this paper were isolated from the fermentation broth of a mutant of a daunomycin-producing wild type strain. This suggest that in general the accumulation of 11-deoxydaunomycinone derivatives may be the result of a block of C11-hydroxylation in the normal biosynthetic pathway of daunomycin and its analogues.

Abstract
Efficient high-performance liquid chromatographic (HPLC) methods have been developed for routine analysis of a number of anthracycline derivatives using reversed-phase muBondapak C18 columns and an isocratic methanol-water-ammonium carbonate (or acetate) solvent system. The rates of formation of bis-daunomycin derivatives of alpha, omega-dicarboxylic acid hydrazides have been investigated using the analytical methods developed. It has been demonstrated that the reaction proceeds via an intermediate mono-hydrazone. Both the mono- and bis-hydrazones have been isolated by preparative HPLC.

Abstract
By mutagenic treatment and selection procedures the mutant ZIMET 43678 was obtained from a population of the interspecific recombinant Streptomyces violaceus subsp. iremyceticus ZIMET 43615, which showed a changed spectrum of secondary metabolites. The main component isolated from the fermentation broth was a pure anthracycline evidenced by TLC. By means of acid hydrolysis, identification of the degradation products and also by spectroscopic UV/VIS-, IR-, MS-, 1H/13C-NMR- and CD-investigations with intact anthracycline the structure 7-(alpha-L- rhodosaminyl )-beta- rhodomycinon with the absolute configuration 7S, 9R , 10R was found. The anthracycline called beta- rhodomycin -1 (1) exhibits antimicrobial and cytostatic activity in vitro and is also effective on tumour cells in tumour bearing animals.

Abstract
Various blocked mutants were isolated from three leukaemomycin-(daunomycin-)producing strains IMET JA 3933, IMET JA 5142 and IMET JA 5570 of Streptomyces griseus by NTG and UV treatments. Among them, one class of four mutants ZIMET 43707/1P, IMET JA 5570/3P, IMET JA 5570/10P and IMET JA 5142/01P1 produced new blue and red pigments. Two red compounds designated 1PI and 1PII are the main components of the pigment complex produced by culture of the blocked mutant ZIMET 43707/1P. This paper describes the isolation of 1PI and IPII; furthermore, the spectral and physicochemical properties of these anthracyclinones and the elucidation of their structures are reported.

Abstract
Following the discovery of new anthracycline antibiotics, auramycins A and B and sulfurmycins A and B, we found 10 minor analogues of auramycins and sulfurmycins, C, D, E, F and G, from the culture broth of a mutant strain of Streptomyces galilaeus OBB-111 and prepared 2 analogues as the chemical derivatives from auramycin G and sulfurmycin G. All analogues have a sugar moiety at C-7 position of the aglycones. These analogues exhibit activities against Gram-positive bacteria and P388 leukemia.

Abstract
The new anthracyclines 4-O-demethyl-11-deoxydoxorubicin, 4-O-demethyl-11-deoxydaunorubicin along with its 13-dihydro and 13-deoxo analogues are the main components of the anthracycline complex produced by cultures of Streptomyces peucetius var. aureus. They were isolated by solvent partition, separated by column chromatography and characterized by chemical and physical methods. Among these new anthracyclines, displaying antibacterial and cytotoxic activity "in vitro", 4-O-demethyl-11-deoxydoxorubicin and the corresponding daunorubicin analogue were also active against experimental tumors.

Abstract
Four blocked mutants of aclacinomycin-producing Streptomyces galilaeus MA144-M1 produced new anthracyclinones; 2-hydroxyaklavinone, its non-esterified analog and 2-hydroxy-7-deoxyaklavinone, several new anthracyclines; 2-deoxyfucosyl-2-deoxyfucosyl-rhodosaminylaklavinone (MA144 U1), 2-deoxyfucosyl-rhodosaminylaklavinone (MA144 U2) and five aklavinone glycosides devoid of amino sugar, designated as MA144 U5, U6, U7, U8 and U9.
