pharmacological and biological activities. However, the anti-cancer effects of prosaikogenin and saikogenin, which are glycoside hydrolyzed saikosaponins, are still unknown due to its rarity in plants. In this study, we applied two recombinant glycoside hydrolases that exhibit glycosidecleavage activity with saikosaponins. The two enzymes, BglPm and BglLk, were cloned from Paenibacillus mucilaginosus and
柴胡皂甙、柴胡皂甙是负责其药理和生物活性的主要成分。然而,由于其在植物中的稀有性,作为糖苷水解的柴胡皂苷的原柴胡皂苷元和柴胡皂苷元的抗癌作用仍然未知。在这项研究中,我们应用了两种重组糖苷水解酶,它们表现出与柴胡皂苷的糖苷切割活性。BglPm 和 BglLk 这两种酶是从粘液类芽孢杆菌和朝鲜乳杆菌中克隆的,在 30-37 °C 和 pH 6.5-7.0 之间表现出良好的活性。柴胡皂甙 A 和 D 是从粗制的B. falcatum中纯化得到的L.提取物采用制备型高效液相色谱技术。通过具有高β-糖苷酶活性的酶转化,Saikosaponin A 和 D 通过 prosaikogenin F 转化为saikogenin F,并通过 prosaikogenin G 转化为saikogenin G。使用硅胶柱纯化两种saikogenin和两种prosaikogenin化合物,分别获得78.1、62.4、8

An agent which promotes the production of extracellular matrix; more particularly, acidic mucopolysaccharides such as hyaluronic acid and fibrous proteins such as collagen, and thus exhibits the effects of activating the extracellular matrix, normalizing skin tissue, and efficiently preventing skin aging by reinforcing the binding between the epidermis and the dermis. This agent contains as active ingredients the extracts of plants belonging to the genus Bupleurum such as B. falcatum Linne (Mishima Saiko), or saikosaponin and saikogenin contained in these extracts. Use of this agent as a skin preparation for external use, etc. makes it possible to promote the production of the above acidic mucosaccharides, fibrous proteins, etc. in fibroblasts, etc.
一种促进细胞外基质生成的制剂,尤其是酸性粘多糖(如透明质酸)和纤维蛋白(如胶原蛋白),因此具有激活细胞外基质、使皮肤组织正常化以及通过加强表皮和真皮之间的结合有效防止皮肤老化的功效。本制剂的有效成分包括 Bupleurum(如 B. falcatum Linne(三岛茜草))属植物的提取物,或这些提取物中的 saikosaponin 和 saikogenin。将这种制剂用作外用皮肤制剂等,可促进成纤维细胞等产生上述酸性粘多糖、纤维蛋白等。

The present invention pertains to complexes comprising sterols and saponins. The complexes are capable of binding a genetic determinant including a polynucleotide. The complexes may further comprise a lipophilic moiety, optionally a lipophilic moiety comprising a contacting group and/or a targeting ligand, and/or a saccharide moiety. The complexes may further comprise an immunogenic determinant and/or an antigenic determinant and/or a medicament and/or a diagnostic compound. The complexes may in even further embodiments be encapsulated by an encapsulation agent including a biodegradable microsphere. The present invention also pertains to pharmaceutical compositions and methods of treatment of an individual by therapy and/or surgery, methods of cosmetic treatment, and diagnostic methods practised on the human or animal body.
