چکیده
A new member of the quinoxaline group antibiotics has been detected by HPLC-diode-array screening. The main compound produced by Streptomyces tendae strain Tü 4031 showed a high degree of similarity in the UV-visible spectral region with echinomycin and their structural similarity was confirmed by structure elucidation using electron tandem mass spectrometry and 2D nuclear magnetic resonance. The new compound, named echinoserine, is a non-cyclic form of echinomycin, but it is not a biosynthetic precursor. Echinoserine is less antibiotically active than echinomycin.

Biosynthetic capacities of actinomycetes. 2. Juglomycin Z, a new naphthoquinone antibiotic from Streptomyces tendae.
A new juglomycin-type antibiotic was identified by a HPLC-diode array screening technique in the culture filtrate of Streptomyces tendae Tü 901/8c. Juglomycin Z (1) differs from all other known juglomycin compounds by an additional methyl group in position 3 of the naphthoquinone ring system. Juglomycin Z is antibiotically active against Gram-positive and Gram-negative bacteria and against yeasts.
متن کاملAntibacterial and antitumor potential of actinomycetes isolated from mangrove soil in the Maowei Sea of the southern coast of China
Mangroves are the tidal forest existing in the intertidal zone and usually considered as the special marine ecosystem. In the present study, 452 actinomycetes were recovered from nine diferent sites at Maowei Sea Mangrove Reserve in Qinzhou (Guangxi province, China). Among them, Seventy-four strains were purified for 16s RNA gene sequencing and further characterization. The results indicated th...

متن کاملEnzymatic diversity in the haloactinomycetes isolated from rhizosphere of the plants in saline soils at the periphery of Dasht-e-Kavir desert
Saline rhizospheric areas are untouched environments for isolating actinomycetes with the potential of valuable salt tolerant enzyme production. In this study, we isolated and evaluated a total number of of 26 actinomycete strains from plant rhizosphere of the periphery of Dasht-e-Kavir desert. Isolated actinomycetes produced different enzymes. Among them 50, 46, 39, 27, 10 and 7 % of the isola...
متن کاملMetabolic products of microorganisms. 228. New nikkomycins produced by mutants of Streptomyces tendae.
Four new dipeptidyl nikkomycins of the Z- and the X-series with a variation in the amino acid moiety of the molecule were isolated from the mutant Streptomyces tendae 901/395 and characterized. Nikkomycins Kz and Kx contain 2-amino-4-hydroxy-4-(2-pyridyl)butyric acid, and nikkomycins Oz and Ox 2-amino-4-hydroxy-4-(5-hydroxy-2-pyridyl)butyric acid. In contrast to nikkomycins Z and X, nikkomycins...
