  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.
