  Synthesis of stryphnoside A, a triterpene saponin isolated from the pericarps of Stryphnodendron fissuratum

  摘要：

  Stryphnoside A, alpha-L-rhamnopyranosyl 3 beta-O-[alpha-L-arabinopyranosyl-(1 -> 4)-beta-D-xylopyranosyl-(1 -> 2)-beta-D-glucopyranosyl]-2 alpha-hydroxyolean-12-en-28-oate, has been synthesized in 11 steps in 15% overall yield starting from the naturally abundant oleanolic acid. Condensation of a partially protected glucopyranosyl donor and 2 alpha, 3 beta-dihydroxyolean-12-en-28-oic acid derivative using inverse glycosylation procedure has significantly simplified the target saponin synthesis. Stryphnoside A exhibited weak cytotoxic activities against tumor cells HeLa, A549, and HepG2 with IC50 at mM level. (C) 2011 Elsevier Ltd. All rights reserved.
