Abstract

© The Royal Society of Chemistry 2020. The goal of “personalised” medicine has seen a growing interest in the development of theranostic agents. Bifunctional, and targeted-trifunctional, theranostic water-soluble porphyrins with a histidine-like chelating group have been synthesisedviacopper-catalysed azide-alkyne cycloaddition (CuAAC) “click” chemistry in high yield and purity. They are capable of photodynamic treatment and [99mTc(CO)3]+complexation for single-photon emission computed tomography (SPECT) imaging, with a radiochemical yield of >95%. The toxicity and phototoxicity were evaluated on HT-29 cells, DU145, and DU145-PSMA cell lines, with the targeted theranostic showing more potent phototoxicity towards DU145-PSMA expressing cells.
