General description

Temoporfin/(tetra[m-hydroxyphenyl]chlorin, m-THPC), is a hydrophobic second-generation photosensitizer. It is used in the palliative treatment of patients with advanced head and neck cancer by photodynamic therapy.

Biochem/physiol Actions

Temoporfin is a photosensitizer for the photodynamic therapy. Temoporfin has been used clinically to treat advanced head and neck squamous cell carcinoma, and is being investigated for use in several other cancers.
