Cercosporin

Cercosporin is produced by the plant pathogenSporakikuchii and elsinochromes, pigments of the elsinoe family of fungi. Cercosporin is an effective photosensitizer with a short activation wavelength that is primarily suitable for surface PDT photodynamic studies (especially for the avoidance of perforation studies). Cercosporin contains the perylenequinone structural features necessary to PKC activity with an IC50 of 0.6-1.3 μM.
