Nitroferroin (5-Nitro-1,10-phenanthroline) is a high potential oxidation-reduction indicator that was recently identified in a high-throughput screen to have antibacterial effects against Clostridium difficile (C. diff). It was highly effective in vitro and against other Clostridium spp. and mycobacterium, but no other tested gram-positive and gram-negative bacteria.
