OBJECTIVES
Pyrrolo[2,1-c][1,4]benzodiazepine (PBD) dimers are synthetic sequence-selective interstrand DNA minor-groove cross-linking agents developed from anthramycins. We investigated the antibacterial activity of three dimers, SJG-136, DRG-16 and ELB-21, which differ in the structure of the PBD monomeric unit and the length of the linker region between the two identical PBD monomers.
