Paper Abstract

The photochemotherapeutic properties of several novel benzophenothiazines were evaluated zn-vzvo in three distinct tumor types consisting of a murine sarcoma, human carcinoma, and a rat glioma. Subcutaneous or intravenous administration of dyes to tumor bearing animals coupled with irradiation of the tumor area with 640 nm light resulted in substantial tumor necrosis 24h post photodynamic therapy as determined by histological evaluation. Significantly, there was minimal concurrent damage to the surrounding normal tissue. These results offer further evidence for the potential usefulness of benzophenothiazines in the photodynamic therapy of neoplasms.
