Synthesis of aromatic C-xylosides by position inversion of glucose
摘要:
Two formally C-xylosylated analogs to 2-naphthyl beta-D-xylopyranoside, which is known to initiate priming of glucosaminoglycan chains, were synthesized by a position inversion of glucose (i.e., position I becomes position 5). The D-C-xyloside showed priming, while the L-C-xyloside did not initiate priming. (c) 2006 Elsevier Ltd. All rights reserved.
D-glucose. Some gallotannins are reported to have antidiabetic properties, such as α-glucosidase inhibitory activity. In this study, fourteen unnatural gallotannin derivatives with 1,5-anhydroalditol and inositol as the cyclic polyol cores were synthesized to investigate how their structures affected antioxidative and α-glucosidase inhibitory activities. Tannic acid demonstrated the most potent antioxidative
