NOVEL COMPOUND SIGNAMYCIN, METHOD FOR PRODUCING THE SAME, AND USE OF THE SAME

摘要

Disclosed are: a novel compound which exhibits an excellent antibacterial activity against a wide variety of pathogenic bacteria including drug-resistant bacteria and plant-disease-causing bacteria, or exhibits an inhibitory activity against enzymes secreted from the bacteria, through the inhibition of the two-component regulatory systems of the bacteria; a method for producing the compound; a novel microorganism capable of producing the novel compound; and a compound-containing composition, an antibacterial agent, or an enzymatic activity inhibitor each utilizing the novel compound. Specifically disclosed are: a compound represented by the structural formula (1); a compound represented by the structural formula (2); a method for producing each of the compounds, which comprises a culture step of culturing a microorganism belonging to the genus Streptomyces and capable of producing the desired compound and a collection step of collecting the desired compound from the culture produced in the culture step; and others.
