  • Patent number: 5985839
    Abstract: The present invention relates to shark cartilage extracts and to a method of producing the same, these extracts having anti-angiogenic properties (reduction of the area of blood vessels observed in vivo on experimentally induced tumors), tumor regressive activity in vivo as well as demonstrating a direct inhibitory effect on tumor cell lines. This process does not involve any denaturing solvent or product and does not involve the use of any enzymes. It consists of obtaining a blend of whole cartilage in an aqueous solution of neutral pH, preferably pure water, this blend being centrifuged and the pellet and supernatant kept for further processing. The pellet is lyophilized and tested for anti-tumor and anti-angiogenic activities in vivo and in vitro, with or without supernatant. The supernatant has been shown to have anti-angiogenic and tumor regressive activities in vivo. The composition of the supernatant has then been investigated by different ways.
