Diketopyrrolopyrrole Derivatives as Photosensitizing Agents against Staphylococcus aureus

open access: yesPhotochemistry and Photobiology, 2022
AbstractDiketopyrrolopyrrole (DPP) derivatives containing sulfonamide (Sulfonamide‐DPP), pyridyl (Dipyridyl‐DPP) and N‐methylpyridyl (MePyridyl‐DPP) substituents were assessed as antibacterial photosensitizers. Non‐charged DPPs showed an intense absorption band centered at about 480 nm and green fluorescence emission (ΦF ~ 0.7) in acetonitrile.
