Paper Abstract

The feasibility of using merocyanine 540 (MC 540) and Photofrin II (PII) as effective photodynamic therapeutic (PDT) agents for killing hepatoma cells and duck hepatitis B virus (DHBV) in vitro was investigated. Cultured duck hepatocytes infected with DHBV and hepatoma cells, Hep 3B and HCC 36, were used as models. MC 540 and PII effectively inhibits the DHBV growth by 90 - 99% in a dose- and light-dependent manner. Photodynamic killing of MC 540 in the two hepatoma cell lines results in 94 - 99% growth inhibition. However, both photosensitizers exhibit dark cytotoxicity (37 - 56%). The present results suggest that MC 540 and PII could be promising and effective photodynamic agents for killing HBV and hepatoma cells.
