Abstract

There is an urgent need for new antibacterials to target emerging multidrug-resistant bacteria. The need for such agents is rising while the efforts in antibacterial research have declined dramatically in the past few decades with the result of only four compounds belonging to new chemical classes being approved for clinical use. The main reasons that led to this critical situation are shortly described. A renewed interest in the research of new effective antimicrobials is nonetheless delivering compounds deriving mainly from modification of existing drugs, yet new chemical classes are appearing. Because many of these activities have started relatively recently, we should expect a long period before new antibiotics are added to the medical armamentarium.

► The commercial and social environments that led to the ‘antibiotic crisis’ are reviewed. ► Most recent data on antibiotics in discovery and development are reported. ► All main scaffolds, from synthetic or natural source and related compounds, are described.
