What is Aureothricin?

Plain description, key identifiers and synonyms

Aureothricin is a dithiolopyrrolone antibiotic that is 4,5-dihydro[1,2]dithiolo[4,3-b]pyrrole in which the hydrogens at positions 4,5 and 6 have been replaced by methyl, oxo and propanoylamino groups, respectively. It is a moderate antimicrobial by-product of the thiolutin fermentation in various Streptomyces species. It has a role as an antibacterial agent, an EC 2.7.7.6 (RNA polymerase) inhibitor, an angiogenesis inhibitor and a bacterial metabolite. It is a secondary carboxamide and a dithiolopyrrolone antibiotic.
