  Preventive effects of soyasapogenol B derivatives on liver injury in a concanavalin A-induced hepatitis model

  摘要：

  To shed light on the structure-activity relationship, various so soyasapogenol B derivatives were synthesized and evaluated for preventive effects on liver injury in the concanavalin A (Con A)-induced hepatitis model in mice, Con A injection into mice induces some pathophysiology of human liver disease such as autoimmune or viral hepatitis, Two hydroxyl groups on the A ring of soyasapogenol B are required for amelioration of liver damage, Modification of the C-22 hydroxyl moiety with an acyloxy or alkyloxy group, or removal of the hydroxyl group. resulted in I greatly enhanced percentage of alleviation. Among the series of soyasapogenol B derivatives examined, six compounds exhibited preventive effects on liver damage. (c) 2005 Elsevier Ltd. All rights reserved.

  Two triterpenoid saponins (1 and 2) were isolated from Desmodii Herba [the dried whole plants of Desmodium styracifolium (Osbeck) Merr. (Leguminosae)] and their chemical structures were characterized as soyasaponin I and a new saponin, 3-O-[alpha-L-rhamnopyranosyl-(1----2)-beta-D-galactopyranosyl- (1----2)-beta-D-glucuronopyranosyl]soyasapogenol E, respectively, by chemical and spectroscopic means

  从Desmodii Herba [满地香（Desmodium styracifolium（Osbeck）Merr）干燥的整株植物中分离出了两个三萜皂苷（1和2）。（豆科）]及其化学结构被表征为大豆皂苷I和新的皂苷3-O- [α-L-鼠李糖基-（1 ---- 2）-β-D-吡喃半乳糖基-（1 ---- 2）通过化学和光谱方法分别测定β-D-D-葡萄糖醛酸吡喃糖基]大豆皂酚E。
