  Synthesis of digalactosyl diacylglycerols and their structure–inhibitory activity on human lanosterol synthase

  摘要：

  Digalactosyl and monogalactocyl diacylglycerols (DGDG and MGDG), which were identified as anti-hyperlipemia active components in Colocasia esculenta (Taro), were synthesized. The inhibitory activity of DGDG, MGDG and related compounds on human lanosterol synthase was evaluated as anti-hyperlipemic activity. DGDG with two myristoyl groups at both sn-1 and sn-2 positions and with an oleoyl group at the sn-1 position showed the most potent activity. (C) 2004 Elsevier Ltd. All rights reserved.
