  • Patent number: 5618790
    Abstract: Lipophilic and amphiphilic therapeutic or diagnostic agents having water solubilizing groups attached thereto by bonds that can be cleaved readily by one or more of the various proteases that are active in the extracellular fluid or on the surfaces of cells in many types of malignant tissue may accumulate selectively in such malignant tissues. Protease mediated removal of the water solubilizing groups converts such drugs into lipophilic or amphiphilic forms which are more soluble in plasma membrane lipids and which therefore enter cells more readily. Since the extracellular fluid in most non-malignant tissues under normal circumstances has little such protease activity, removal of the water solubilizing groups takes place primarily within malignant tissues, with consequent preferential accumulation of the lipophilic or amphiphilic forms of the drug within malignant tissues.

  • Patent number: 5219878
    Abstract: This invention relates to new preparations which are valuable for photodetection and photochemotherapy of tumors and malignant tissues. The active compounds of these therapeutic preparations are mono-, di- or polyamides of an amino alcohol and a cyclic tetrapyrrole containing at least one carboxyl group. The general structure of these active compounds is(ZNHCO).sub.n Xwherein Z is the amino alcohol molecule less the amino group, X is the tetrapyrrole molecule less a carboxyl group, and "n" is an integer from 1 to 8.
