  Synthesis and α-glucosidase inhibitory activity evaluation of N-substituted aminomethyl-β-d-glucopyranosides

  摘要：

  A series of N-substituted 1-aminomethyl-beta-D-glucopyranoside derivatives was prepared. These novel synthetic compounds were assessed in vitro for inhibitory activity against yeast a-glucosidase and both rat intestinal a-glucosidases maltase and sucrase. Most of the compounds displayed a-glucosidase inhibitory activity, with IC50 values covering the wide range from 2.3 mu M to 2.0 mM. Compounds 19a (IC50 = 2.31 mu M) and 19b (IC50 = 5.6 mu M) were identified as the most potent inhibitors for yeast a-glucosidase, while compounds 16 (IC50 = 7.7 and 15.6 mu M) and 19e (IC50 = 5.1 and 10.4 mu M) were the strongest inhibitors of rat intestinal maltase and sucrase. Analysis of the kinetics of enzyme inhibition indicated that 19e inhibited maltase and sucrase in a competitive manner. The results suggest that the aminomethyl-beta-o-glucopyranoside moiety can mimic the substrates of a-glucosidase in the enzyme catalytic site, leading to competitive enzyme inhibition. Moreover, the nature of the N-substituent has considerable influence on inhibitory potency. (C) 2013 The Authors. Published by Elsevier Ltd. All rights reserved.

  Mono-O-benzylidenation of the starting compounds with benzaldehyde dimethyl acetal followed by O-isopropylidenation led to 4,6-O-benzylidene-2,3-O-isopropylidene acetals having better solubilities in non-polar solvents than the di-O-isopropylidene acetals. Di-O-benzylidenation of β- d -mannopyranosylnitromethane gave both (endo-2,3):4,6- and (exo-2,3):4,6-di-O-benzylidene acetals. Transacetalation of 1-deoxy-1-nitro-

  The glycosylamines of O-acetyl-protected GlcNAc and chitobiose, as well as two partially unprotected 1-C-aminomethyl glucosides, were photochemically coupled with orthogonally protected N-aspartyl-5-bromo-7-nitroindoline derivatives. The reactions proceeded under neutral conditions by irradiation with near-UV light. The glycosyl asparagines with N- or C-glycosyl linkages were afforded in 60-85% yield

  beta-C-Glycosides with the D-manno, D-allo, and D-altro configurations can be easily obtained by anchimerically assisted inversions, starting from a common beta-C-glycoside precursor, nitro(4,6-O-benzylidene-beta-D-glucopyranosyl)methane (2), which is easily accessible from D-glucose. The observed neighboring group reactions show some similarities to reactions Previously observed for analogous O-glycosides, but also some significant differences due to the acetamidomethyl beta-C-glycoside group, which is present in most of the compounds. The configurations and conformations of all compounds have been comprehensively studied by NMR methods. The result is a viable and extendable synthetic paradigm for the rational synthesis of a wide variety of unusual C-glycoside derivatives, potentially useful for biochemical studies.

  The nitromethyl group of C-(4,6-O-benzylidene-beta-D-glucopyranosyl) nitromethane was manipulated by various reduction and oxidation methods and further functionalizations into -CH2NHOH, -CH=NOH, -CN, -CH=O, and -CH2NHCONH2, all with retention of the 4,6-O-benzylidene group. Certain reduction methods gave rise to a novel secondary amine via an unusual dimeric aminal.
