Demeclocycline, a chlortetracycline analog produced by a mutagenised strain of Streptomyces aureofaciens, was first isolated in 1957. Like all tetracyclines, Demeclocycline shows broad-spectrum...
Meleagrin is an alkaloid with antitumor and antibiotic activity, isolated from a number of species of Penicillium. Meleagrin is a common taxonomic marker for fungal contamination of foodstuffs. Note...
Kazusamycin B is a metabolite and minor member of the Leptomycin complex isolated from some Streptomyces species. It is a hydroxylated analog of Leptomycin A, a nuclear export inhibitor. It is...
Doxycycline Hydrate is a third-generation tetracycline and matrix metalloproteinase inhibitor, synthesized in 1958. It has broad-spectrum antibacterial and antiprotozoan activity, and interferes...
Nogalamycin is an unusual anthracycline bacterial metabolite produced by Streptomyces nogalater var. nogalater reported by researchers at Upjohn in 1965. Nogalamycin contains two saccharides: the...
Ikarugamycin is a natural product with an unusual structure, a pentacyclic tetramic acid produced by Streptomyces phaeochromogenes. Discovered in 1972, the compound belongs to the polycyclic...
Enopeptin A is an unusual depsipeptide featuring a pentaenone side chain, reported as an antiviral by researchers at RIKEN in 1991. Enopeptin A has potent antibacterial activity against Gram-positive...
Leucomycin A1 is a major metabolite from the leucomycin complex, a family of closely related macrocyclic lactone antibiotics produced by Streptomyces kitasatoensis, discovered in 1953. Leucomycin A1...
Leucomycin A13 is the most non-polar member of the leucomycin complex, a family of closely related macrocyclic lactone antibiotics produced by Streptomyces kitasatoensis. Leucomycin A13 is used for...
Leucomycin A4 is a major metabolite from the leucomycin complex, a family of closely related macrocyclic lactone antibiotics produced by Streptomyces kitasatoensis, discovered in 1953. Leucomycin A4...
Leucomycin A5 is a major metabolite of the leucomycin complex, a family of closely related macrocyclic lactone antibiotics produced by Streptomyces kitasatoensis, and discovered in 1953. Leucomycin...
Steffimycin B is an anthracycline metabolite isolated from a Streptomyces sp. with antibacterial and antineoplastic properties. Crystallographic studies of binding to DNA suggest that it has a higher...
