  Mannosylated saponins based on oleanolic and glycyrrhizic acids. Towards synthetic colloidal antigen delivery systems

  摘要：

  Immunostimulatory saponin based colloidal antigen delivery systems show promise as adjuvants for subunit vaccines. For this reason, allyl oleanolate was glycosylated at the 3-position using trichloroacetimidate donors to give monodesmodic saponins following deprotection. Bisdesmodic saponins were synthesized by double glycosylation at the 3- and 28-positions of oleanolic acid. When formulated together with cholesterol and phospholipids, ring-like, helical and rod-like nanostructures were formed depending on the saponin concentrations used. As an indication of adjuvant activity, the ability of these formulations, and the saponins by themselves, to induce dendritic cell maturation was measured, but no significant activity was observed.

  Licorice root is often co-prescribed with Bupleuri Radix (Bupleurum root) for decoctions used in oriental traditional medicine. It was found that the water solubility of saikosaponin-a, the active principle of Bupleurum root, was increased in the presence of the water extract or the saponin fraction of licorice root and this solubilizing effect was due to glycyrrhizin, the major active saponin of this plant drug. A solubilizing effect on saikosaponin-a was also observed with the 30-β-glucoside ester and 30-β-glucuronide ester of glycyrrhizin. The 30-β-glucoside ester improved the solubilizing property of glycyrrhizin. Aqueous solutions of the 30-β-glucoside ester and the 30-β-glucuronide ester solubilized dl-α-tocopherol and oleanolic acid, both of which are almost insoluble in water.

  在东方传统医学中，甘草根通常与柴胡（Bupleuri Radix，柴胡根）共同用于煎剂。研究发现，在甘草根的水提取物或皂甙部分存在的情况下，柴胡根的活性成分柴胡皂苷-a 的水溶性增加，这种增溶作用是由甘草苷（这种植物药的主要活性皂甙）引起的。甘草苷的 30-β- 葡萄糖苷酯和 30-β- 葡萄糖醛酸苷酯也对赛科皂甙-a 有增溶作用。30-β- 葡萄糖苷酯改善了甘草苷的增溶特性。30-β-Glucoside 酯和 30-β-Glucuronide 酯的水溶液可溶解几乎不溶于水的 dl-α-生育酚和齐墩果酸。

  From the air-dried root of Glycyrrhiza uralensis, collected in the northeastern part of China, ten new oleanane-type triterpene oligoglycosides were isolated together with glycyrrhizin (1) and several known flavonoids. Among the newly isolated triterpene oligoglycosides, the chemical structures of licorice-saponin A3 (2), licorice-saponin B2 (3), and licorice-saponin C2 (4) have been determined, on the basis of chemical and physicochemical evidence, to be expressed as 30-O-β-D-glucopyranosylglycyrrhizm, 11-deoxo-glycyrrhizin, and 3-O-[β-D-glucuronopyranosyl(1→2)-β-D-glucuronopyranosyl]oleana-11, 13(18)-dien-30-oic acid, respectively. During the course of these studies, facile conversions from glycyrrhizn (1) to licorice-saponins A3 (2), B2 (3), and C2 (4) have been accomplished.
