    Novel d-Xylose Derivatives Stimulate Muscle Glucose Uptake by Activating AMP-Activated Protein Kinase α
    摘要:
    Type 2 diabetes mellitus has reached epidemic proportions; therefore, the search for novel antihyperglycemic drugs is intense. We have discovered that D-Xylose increases the rate of glucose transport in a non-insulin-dependent manner in rat and human myotubes in vitro. Due to the unfavorable pharmacokinetic properties Of D-Xylose we aimed at synthesizing active derivatives with improved parameters. Quantitative structure-activity relationship analysis identified critical hydroxyl groups in D-xylose. These data were used to synthesize various hydrophobic derivatives Of D-Xylose of which compound 19 the was most potent compound in stimulating the rate of hexose transport by increasing the abundance of glucose transporter-4 in the plasma membrane of myotubes. This effect resulted from the activation of AMP-activated protein kinase without recruiting the insulin transduction mechanism. These results show that lipophilic D-Xylose derivatives may serve as prototype molecules for the development of novel anti hyperglycemic drugs for the treatment of diabetes.

  • Acyl Group Migration in Pyranosides as Studied by Experimental and Computational Methods
    作者:Robert Lassfolk、Manuel Pedrón、Tomás Tejero、Pedro Merino、Johan Wärnå、Reko Leino

    have studied the acyl migration in different monosaccharides using five different acyl groups by a combination of experimental, kinetic and theoretical tools. The results show that the anomeric configuration in the monosaccharide has a major influence on the migration rate, together with the relative configurations of the other hydroxyl groups and the nature of the migrating acyl group.
