Structure-activity relationships in DNA gyrase inhibitors.

The review brings the status of research into DNA gyrase inhibitors up to date. Structure-activity relationships in both coumarin antibiotics, like novobiocin or coumermycins, and quinolones are discussed. In the section dealing with the quinolones, promising drugs under further evaluation are pointed out. Recently discovered new types of DNA gyrase inhibitors, i.e. tetramic acid derivatives and biphenyl dicarboxylic acid monoamides, are also briefly mentioned.
