Novel antibacterial compounds

摘要

This invention relates to a novel purified compound PM181104, of formula (I) of molecular weight 1514 and molecular formula CHNOS; which is obtained by fermentation of the microorganism belonging to Kocuria species (ZMA B-1 / MTCC 5269). The invention includes all stereoisomeric forms and all tautomeric forms of the compound PM181104 and pharmaceutically acceptable salts and derivatives such as esters and ethers. The present invention further relates to processes for the production of the novel antibacterial compound(s), to the production of the microorganism belonging to Kocuria species (ZMA B-1 / MTCC 5269), and to pharmaceutical compositions containing the novel compound(s) as an active ingredient and its/their use in medicines for treatment and prevention of diseases caused by bacterial infections.
