    • 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 lyophylized 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. Fractionation of this supernatant led to the characterization of some of its active components. The fractions were tested for their direct in vitro activity on cancer cell lines. Therefore, it is assumed that the non-fractionated supernatant has such an in vitro activity. Lyophilization substantially destroys the activity of these liquid fractions while no such abolition is observed in the solid extract.
    • 本发明涉及鲨鱼软骨提取物及其制备方法,这些提取物具有抗血管生成特性(减少实验诱导的肿瘤体内观察到的血管面积),体内的肿瘤回归活性以及展示 对肿瘤细胞系的直接抑制作用。 该方法不涉及任何变性溶剂或产物,并且不涉及使用任何酶。 它包括在中性pH水溶液(优选纯水)中获得整个软骨的混合物,将该混合物离心,并将沉淀和上清液保持进一步处理。 将沉淀物冻干,并在体内和体外测试具有或不含上清液的抗肿瘤和抗血管生成活性。 已经显示上清液在体内具有抗血管生成和肿瘤回归活性。 然后通过不同的方式研究上清液的组成。 分离这种上清液导致其一些活性组分的表征。 测试这些级分在癌细胞系上的直接体外活性。 因此,假定非分级上清液具有这样的体外活性。 冻干基本上破坏了这些液体部分的活性,而在固体提取物中没有观察到这样的消除。

    • 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. 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. Several cosmetic applications based on the capacity of the liquid extract to improve skin barrier function are also under the scope of this invention. These extracts have no offensive effect on normal body functions. Therefore, these shark cartilage extracts have a very promising therapeutic value. The process for the obtention of cartilage extracts is simple and efficient. The unexpectedly valuable products obtained by this process are therefore an indication of a new and non-obvious process.
    • 本发明涉及软骨提取物及其制造方法。 已经通过改进的方法获得具有抗血管生成,抗肿瘤,抗炎和抗胶原活化的鲨鱼软骨提取物。 该方法包括以下步骤:在水溶液中获得软骨匀浆,将该匀浆在固体级分(SOLID EXTRACT)和液体级分中分离,将其进一步分级分离,得到分子量为0 至500kDa。 然后通过不同的方式研究了液体提取物的组成。 该提取物的进一步分级导致其一些活性组分的初步表征。 由于总液体提取物的生物活性的多样性,其可用于治疗多种疾病或病症,例如具有选自肿瘤增殖,血管发生,炎症和胶原溶解的组分的疾病或病症。 基于液体提取物提高皮肤屏障功能的能力的几种化妆品应用也在本发明的范围内。 这些提取物对正常身体功能无异味。 因此,这些鲨鱼软骨提取物具有非常有希望的治疗价值。 获取软骨提取物的过程简单有效。 因此,通过这一过程获得的意想不到的有价值的产品是新的和非显而易见的过程的指示。
