The meso-tetranaphthylporphyrins (TNP) derivatives, 5-(2-hydroxy-1-naphthaldehyde-4-naphthyleneimine)-10,15,20-trinaphthylporphyrin 3, 5-(salicylidene-4-naphthyleneamine)-10,15,20- trinaphthylporphyrin 4 and 5-(thiophene-2-carboxaldehyde-4-naphthyleneimine)-10,15,20-trinaphthylporphyrin 5, were synthesized by the reaction of 5-(4-aminonaphthyl)-l0,15,20-trinaphthylporphyrin 2 with different aldehydes. Their photodynamic activity against K562 cells were evaluated in vitro. They displayed low levels or no dark toxicity and high phototoxicity to K562 cells, especially for 5, which offers potential application in photodynamic therapy.
