Drug diversity in bacteria

Phenazines are widespread and chemically diverse bacterial natural products that can fulfil various biological functions. Like antibiotics, some derivatives kill bacteria; others are toxic to fungi and/or cancer cells. There are also derivatives that allow the bacteria to survive in an environment that is hostile to them, such as the human body. These virulence factors…
