ChEBI: Holomycin is 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antibiotic that is 4,5-dihydro[1,2]dithiolo[4,3-b]pyrrole in which the hydrogens at positions 5 and 6 have been replaced by oxo and acetamido groups, respectively.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. It has a role as a chelator, an antineoplastic agent, an EC 2.7.7.6 (RNA polymerase) inhibitor, an antibacterial agent, a marine metabolite and a bacterial metabolite. It is a dithiolopyrrolone antibiotic and a member of acetamides.
