Cationic pyrazinoporphyrazines and quinoxalinoporphyrazines as water-soluble photosensitizers for PDT

Abstract

Several water-soluble pyrazinoporphyrazines and quinoxalinoporphyrazines were synthesized and their properties important for photodynamic therapy compared; all studied compounds showed excellent photodynamic activity using in vitro tests on cancer cells of human larynx (Hep2)
