  • Shark cartilage extract: process of making, methods of using, and compositions thereof
    Publication number: 20040081703
    Abstract: The present invention relates to cartilage extracts and to a method of producing the same. Shark cartilage extracts having anti-angiogenic, anti-tumor, anti-inflammatory and anti-collagenolytic activities have been obtained by an improved process. The process comprises the steps of obtaining a crude cartilage extract in an aqueous solution, this crude extract being fractionated to recover molecules of a molecular weight less than about 500 kDa. Some of the biologically active components of the extract are prepared by further fractionation. The cartilage extract can be used for treating diseases or conditions having etiological components selected from the group consisting of tumor proliferation, angiogenesis, inflammation, metalloprotease activity and collagenolysis. Several cosmetic applications based on the capacity of the liquid extract to improve skin conditions are also disclosed. A simple and efficient process for the preparation of cartilage extracts is also disclosed.

  • Methods of using extracts of shark cartilage
    Patent number: 6028118
    Abstract: The present invention relates to cartilage extracts and to a method of producing the same. Shark cartilage extracts having anti-angiogenic, anti-tumoral, anti-inflammatory and anti-collagenolytic activities have been obtained by an improved process. The process comprises the steps of obtaining a homogenate of cartilage in an aqueous solution, this homogenate being separated in a solid fraction (SOLID EXTRACT) and a liquid fraction which was further fractionated to obtain a LIQUID EXTRACT having molecules of a molecular weight comprised between 0 to 500 kDa. The composition of the liquid extract has then been investigated by different ways. Further fractionation of this extract led to the preliminary characterization of some of its active components.

  • Extracts of shark cartilage having anti-collagenolytic, anti-inflammatory, anti-angiogenic and anti-tumoral activities; process of making, methods of using and compositions thereof
    Patent number: 6025334
    Abstract: The present invention relates to cartilage extracts and to a method of producing the same. Shark cartilage extracts having anti-angiogenic, direct anti-tumor proliferating, anti-inflammatory and anti-collagenolytic activities have been obtained by an improved process. The process comprises the steps of obtaining a homogenate of cartilage in an aqueous solution, this homogenate being centrifuged and further fractionated to obtain a total extract having molecules of a molecular weight comprised between 0 to 500 KDa. The composition of the liquid extract has then been investigated by different ways. Further fractionation of this extract led to the preliminary characterization of some of its active components. Due to the multiplicity of biological activities of the total liquid extract, it can be used for treating numerous diseases or conditions such as those having components selected from the group consisting of tumor proliferation, angiogenesis, inflammation and collagenolysis.

  • Skin tanning compositions
    Patent number: 5503824
    Abstract: The disclosed invention is directed to methods and compositions for improving the rate, extent and lifetime of an artificially induced tanning of the human skin. The invention entails treating the skin with agents such as amino acids, dipeptides, and amino substituted containing polymers either prior to or simultaneously with application of dihydroxyacetone.
