Amycolatopsin A is a glycosylated polyketide isolated by Microbial Screening Technologies from Amycolotopsis sp. The amycolatopsins are closely related to the ammocidins and apoptolidins...
Aminopterin is a 4-amino derivative of folic acid and a folic acid antagonist. It is a synthetic derivative of pterin. It has both mmunosuppressive properties and anti-cancer properties and can be...
Ambuic acid is an antifungal cyclohexanone metabolite produced by Pestalotiopsis sp. Ambuic acid inhibits the biosynthesis of quorum sensing peptides in Gram-positive bacteria. Ambuic acid may exert...
Alternariol monomethylether was first reported by Raistrick and colleagues in 1953. Alternariol and its monomethyl ether analogue occur in mycelium of Alternaria tenuis responsible for alternaria...
Alternariol is a mycotoxin produced by Alternaria and is often found as a contaminant in fruit and small grain cereal products. Structurally, it is characterized as a dibenzopyranone. It can be...
Actinonin is a metabolite of Streptomyces roseoplallidus and other Streptomyces species, first reported in Nature in 1962. Actinonin is a bacteriostatic agent with activity against Gram-positive and...
Aclarubicin (aclacinomycin A) is an anthracycline and topoisomerase II inhibitor that has been clinically tested against haematologic and solid tumors. Aclarubicin stabilizes topoisomerase I cleavage...
Acivicin is a chlorinated amino acid originally isolated from Streptomyces sviceus that inhibits glutmate metabolism. It has antifungal, antitumor and antileishmanial properties. Acivicin...
Acetomycin, a γ-butyrolactone isolated from Streptomyces ramulosus, was first reported in 1958 by Ettlinger et al. at ETH Zurich. Acetomycin is potently active in vitro against HCT-8 human colon...
Acadesine was originally identified as a metabolite of Bacillus species and was shown to accumulate in the culture medium of E. coli under sulphonamide stasis. Acadesine is an adenosine-regulating...
7-Dechlorogriseofulvin is co-produced with griseofulvin by Penicillium sp.. 7-Dechlorogrisefulvin has antifungal activity, albeit less potent than griseofulvin. 7-Dechlorogriseofulvin inhibits...
Floramultine was first isolated from Kreysigia multiflora, a member of the Liliacaeae family, in 1960 by Badger and Bradbury, University of Adelaide, Australia. The absolute configuration of...
