  Modified mannose disaccharides as substrates and inhibitors of a polyprenol monophosphomannose-dependent α-(1→6)-mannosyltransferase involved in mycobacterial lipoarabinomannan biosynthesis

  摘要：

  A panel of alpha-(1 6)-linked mannose disaccharides (5-8) in which the 2'-OH group has been replaced, independently, by deoxy, fluoro, amino, and methoxy functionalities has been synthesized. Evaluation of these compounds as potential substrates or inhibitors of a polyprenol monophosphomannose-dependent alpha-(1-6)-mannosyltransferase involved in mycobacterial LAM biosynthesis demonstrated that the enzyme is somewhat tolerant substitution at this site. The enzyme recognizes the disaccharides with groups similar or smaller in size than the native hydroxyl (6-8), but not the disaccharide with the more sterically demanding methoxy group (5). The 2'-OH appears not form a critical hydrogen bonding interaction with the protein as the 2'-deoxy analog is a substrate for the enzyme. (C) 2004 Elsevier Ltd. All rights reserved.
