  • Benzoporphyrin derivatives for photodynamic therapy
    Patent number: 5214036

BPDs, especially in conjunction with the HDL fraction of plasma lipoproteins, has been shown to be particularly effective in this context. Pharmaceutical compositions in which these combinations are the active ingredients for use in diagnosis and treatment of tumors are also disclosed.
