In this report, we developed novel chlorin/arylaminoquinazoline conjugates for targeted photodynamic therapy of cancer. The synthesized photosensitizers consisted of chlorin-e6 metallocomplexes (Zn, In, or Pd) conjugated with arylaminoquinazoline ligands with high affinity for epidermal growth factor receptors (EGFR). Additionally, the selectivity and antitumor properties of the conjugates were investigated in the EGFR-expressing A431 human tumor cell line in vitro. Among the tested molecules, the In-containing conjugate effectively inhibited tumor cell proliferation at nanomolar concentrations, a rare property for conventional photosensitizers. In in vivo experiments, the conjugates rapidly accumulated at the tumor site in nude mice bearing A431 xenograft tumors. Subsequent distribution analysis among different tissues was carried out using fluorescence imaging and elemental analysis. Finally, we demonstrated that the most promising In-containing conjugate was capable of inhibiting xenograft tumor growth in mice through combinational therapy. This therapeutic approach, combined with the conjugate’s confirmed safety profile, highlights its potential for effective and safe cancer treatment.
