Abstract
Green porphyrins (Gp), compounds important in photodynamic therapy, have been associated with lipocomplexes to reduce the required amount of photosensitizer through higher effective absorption and increased specificity. 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.
