  • Oncology

Background:

  • Multimodal imaging and therapy offer synergistic advantages for image-guided interventions.
  • Porphyrin-based photosensitizers are promising theranostic agents due to their near-infrared fluorescence and photodynamic therapy capabilities.

Purpose of the Study:

  • To develop and evaluate a targeted multimodal bacteriochlorophyll theranostic probe for cancer imaging and therapy.
  • To assess the probe's efficacy in folate receptor-expressing cancer cells both in vitro and in vivo.

Main Methods:

  • Synthesized a bacteriochlorophyll derivative conjugated with a peptide linker and folate for targeted delivery.
  • Evaluated the probe's near-infrared fluorescence imaging properties.
  • Assessed its photodynamic therapy efficacy through singlet oxygen generation.
  • Investigated folate receptor targeting specificity in cancer cells.

Main Results:

  • The probe exhibited multimodal theranostic capabilities.
  • Demonstrated specific targeting of folate receptor-expressing cancer cells.
  • Successfully utilized for both near-infrared fluorescence imaging and photodynamic therapy in vitro and in vivo.

Conclusions:

  • The developed bacteriochlorophyll theranostic probe is effective for targeted cancer imaging and photodynamic therapy.
  • This probe shows potential for image-guided cancer treatment strategies.
