Novel porphyrin–psoralen conjugates: synthesis, DNA interaction and cytotoxicity studies

Abstract

A Cu(i)-catalyzed azide-alkyne cycloaddition reaction (CuAAC) has been utilized to prepare novel triazole-linked cationic porphyrin-psoralen conjugates that exhibited significant photocytotoxicity against A549 cancer cells (IC50 = 84 nM).
