Trojan Horse Siderophore-based Drug

Caption

A hypothetical Trojan Horse drug would consist of a siderophore (blue) linked to an antibiotic, in this case the broad-spectrum antibiotic ciprofloxacin (green). Many bacteria have evolved resistance to ciprofloxacin in recent years, leaving it less effective than it once was. Attaching it to a siderophore might make the antibiotic useful again because bacteria pump siderophores inside their cell membranes where they can do maximum damage.
