Abstract: The discovery of Pt-chlorin-type theranostic agents is described. Luminescent Pt(II) 4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine-fused chlorins, with different degrees of hydrophilicity, have been synthesized and their in vitro photocytotoxicity against human melanoma, oesophageal and bladder carcinomas was studied. A di(hydroxymethyl)-substituted chlorin was identified as a privileged molecule to explore imaging-guided photodynamic therapy. In addition to the high activity as PDT agent and absence of cytotoxicity per se, this molecule showed the ideal photophysical and photochemical properties. In vivo studies using a A375 melanoma mouse model, proved the extraordinary properties of this chlorin as a luminescent probe and the ability to impair tumor growth, making image guided treatment and follow up a possibility.
