Previous quantitative and qualitative structure-activity studies in antibacterial monosubstituted 1-ethyl-1,4-dihydro-4-oxoquinoline-3-carboxylic acids prompted us to synthesize the 6,7,8-polysubstituted compounds. In this paper, the preparation and antibacterial activity of the 6,7- and 7,8-disubstituted compounds and their derivatives are described. Among these compounds, 1-ethyl-6-fluoro-1,4-di

To provide a novel mutilin derivative having a substitution at the 14-position, which is a novel mutilin analogue exhibiting a potent and broad antimicrobial action against Gram-positive bacteria and Gram-negative bacteria including various drug-resistant bacteria, and which is expected to be useful as an agent for treating infectious diseases. A mutilin derivative represented by the following general formula (1):
or a pharmaceutically acceptable addition salt thereof.
This invention provides, among other things, novel compounds useful for treating bacterial infections, pharmaceutical compositions containing such compounds, as well as combinations of these compounds with at least one additional therapeutically effective agent.
