Chromomycin A2 is a minor, more hydrophobic analogue of the chromomycin complex of the aureolic acid class. Chromomycin A2 was originally isolated from S. aburaviensis and named aburamycin. Chromomycin A2 exhibits a broad biological profile as an...
Questiomycin A is a phenoxazine produced by several Streptomyces species and some fungi and bacteria. Questiomycin A is weakly active against bacteria, fungi, plants and tumor cell lines, and inhibits aromatase and sulfatases. More recently, questiomycin...
Chromomycin A3 is the major component of the chromomycin complex of the aureolic acid class, isolated from several Streptomyces species, and first reported in 1960. Chromomycin A3 exhibits a broad biological profile as an antibacterial, antifungal and...
Collismycin is a rare and unusual antibiotic belonging to the caerulomycin class, containing a core 2,2'-bispyridyl with an oxime substituent, produced by a strain of Streptomyces and discovered by researchers from Kirin, Japan in 1994. Collismycin was...
Isoapoptolidin, originally isolated from a Nocardiopsis sp., is a ring-expanded isomer of apoptolidin. In water, apoptolidin and isoapoptolidin equilibrate in a ratio of ~1.5:1 within hours. In a rapid F0F1-ATPase assay, isoapoptolidin was approximately...
Concanamycin A is the major analogue of the concanamycin complex produced by Streptomyces sp.. It has been shown to act as a potent and specific vacuolar-ATPase inhibitor. Concanamycin A inhibits the acidification of organelles and blocks cell surface...
Resistoflavine is a rare, boat-shaped, pentacyclic polyketide isolated from several species of Streptomyces, often co-produced with resistomycin. Resistoflavine exhibits weak antibacterial activity against Gram positive and Gram negative bacteria and...
Actinotetraose is a unique tetrasaccharide with six tiglate esters isolated from an unidentified Amycolatopsis culture. The sugar possesses a two-fold axis of symmetry and is a co-metabolite of quinaldopeptin, a potent antitumor agent.Actinotetraose...
7-Aminocephalosporanic Acid (7-ACA) is a key intermediate in the production of a wide variety of semisynthetic Cephalosporin antibiotics. It is an inhibitor of bacterial (S. aureus) β-lactamase. It is derived from mild acid...
Anguinomycin A is a natural polyketide and analog of Leptomycin B, an inhibitor of protein nuclear export. It is isolated from Streptomyces spp., and displays anti-cancer activity. Anguinomycins B, C and D are also members of the Leptomycin...
Sch 38519 is an isochromanequinone, structurally related to lactoquinomycin. Sch 38519 inhibits thrombin-induced aggregation of human platelets and is active against Gram positive and Gram negative bacteria.Sch 38519 is soluble in ethanol, methanol,...
Borrelidin is an unusual nitrile-containing metabolite isolated from Streptomyces. Borrelidin is an important lead for antimalarial discovery, displaying activity against drug-resistant Plasmodia.Borrelidin is soluble in ethanol, methanol, DMF and...
