| acetopyrrothine | 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antibiotic that is 4,5-dihydro[1,2]dithiolo[4,3-b]pyrrole in which the hydrogens at positions 4,5 and 6 have been replaced by methyl, oxo and acetamido groups, respectively. It is a potent inhibitor of RNA polymerases, inhibits the angiogenesis of human umbilical vein endothelial cells, and also inhibits JAMM metalloproteases. | thiolutin |
| aureothricin | 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antibiotic that is 4,5-dihydro[1,2]dithiolo[4,3-b]pyrrole in which the hydrogens at positions 4,5 and 6 have been replaced by methyl, oxo and propanoylamino groups, respectively.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. | aureothricin |
| holomycin | A dithiolopyrrolone antibiotic that is 4,5-dihydro[1,2]dithiolo[4,3-b]pyrrole in which the hydrogens at positions 5 and 6 have been replaced by oxo and acetamido groups, respectively. It is an inhibitor of DNA-dependent RNA polymerase, and exhibits antibacterial and antitumour properties. | holomycin |
