Chrysomycin A is the major analogue in a complex of C-glycoside antitumor actives isolated from Streptomyces. Chrysomycin A, with a vinyl group in the 8-position, is the most potent analogue of the...
Aphidicolin is a tetracyclic diterpene antibiotic isolated from fungi, notably Cephalosporium, Nigrospora, Harziella and Phoma. Aphidicolin has antibiotic, antiviral and antimitotic properties,...
Cytochalasin D is the most studied of the cytochalasins. Like most of the members of this mycotoxin class, cytochalasin D exhibits potent inhibition of actin filament function leading to cell death...
Nigericin is a polyether antibiotic produced by Streptomyces, notably S. hygroscopicus, isolated in the 1950s. Its complex structure was finally elucidated in 1968. Although Nigericin can be isolated...
Narasin (4-methylsalinomycin) is a carboxylic polyether antibiotic isolated from Streptomyces aureofaciens in 1978. Although Narasin is a derivative of Salinomycin, the metabolites are produced by...
TAN 420C is a minor analogue of the herbimycin complex, isolated from Streptomyces hygroscopicus. TAN 420C is the hydroquinone of herbimycin C, and is known to exhibit antitumor activity. TAN 420C...
Siccanin is an unusual fused phenolic pentacycle first isolated from Helminthosporium siccans reported in 1962 as a potent antifungal agent. Siccanin inhibits succinate dehydrogenase in the terminal...
Gliotoxin is a potent epithiodioxopiperazine mycotoxin produced by species of Gliocladium, Aspergillus and Penicillium. Gliotoxin inhibits a number of thiol-requiring enzymes and displays antioxidant...
Lagosin is a pentaene antifungal produced by Streptomyces, first isolated in 1958 by researchers at MIT in the USA. The discovery was soon followed by several independent isolations as lagosin and...
Hygrolidin is a 16-membered macrocyclic lactone closely related to the bafilomycins, active against Valsa ceratosperma, the pathogen of apple canker disease. Hygrolidin is active against SV40 tumor...
Enniatins are a family of depsipeptide ionophores produced by several Fusarium species. Recently, the effects of the enniatins on acyl-CoA cholesterol transferase, transporters and the selectivity of...
Toxoflavin (PKF 118-310) is an azapteridine antibiotic produced by some species of Pseudomonas, Streptomyces, and Burkholderia gladioli that has antibiotic and anticancer properties. It is also a...
