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).
