Synthesis and in vitro evaluation of a PDT active BODIPY–NLS conjugate
摘要:
Two new photosensitizers based on the BODIPY scaffold have been synthesized, of which one bears an NLS peptide, which is linked to the BODIPY's core using the copper catalysed azide-alkyne click reaction. The phototoxicities of these BODIPY based photosensitizers have been determined, as well as their dark toxicities. Although the conjugation of a single NLS peptide to the BODIPY did not lead to any observable nuclear localization, the photosensitizer did exhibit a superior photoxicity. Cellular co-localization experiments revealed a localization of both dyes in the lysosomes, as well as a partial localization within the ER (for the peptide-bearing BODIPY). (C) 2013 Elsevier Ltd.
