  Chemoenzymatic synthesis and in vitro studies on the hydrolysis of antimicrobial monoglycosyl diglycerides by pancreatic lipase

  摘要：

  Monoglucosyl and monogalactosyl diglycerides (MGDGs) with medium-long length acyl chains, identified as active components in Euphorbiaccae, were synthesized. They were examined for antimicrobial activity against Gram-positive, Gram-negative bacteria and fungi. MGDGs with two octanoyl groups at both 1- and 2-positions showed the most potent activity. The stereoselectivity of pancreatic lipase was investigated in vitro where the preference for the 1 position in MGDGs is strictly related to the length of the acyl chains. (c) 2007 Elsevier Ltd.

  examined for antimicrobial activity against Gram positive, Gram negative bacteria and fungi. The study of their in vitro antimicrobial activity confirms the significant activity of some monogalactosyl diacylglycerol analogues and establishes for the galactose series that the 1,2-disubstitution and the octanoyl chain are the proper structural features for the maximum activity.
