  α-d-Mannose derivatives as models designed for selective inhibition of Golgi α-mannosidase II

  摘要：

  Human Golgi alpha-mannosidase II (hGM) is a pharmaceutical target for the design of inhibitors with antitumor activity. Nanomolar inhibitors of hGM exhibit unwanted co-inhibition of the human lysosomal alpha-mannosidase (hLM). Hence, improving specificity of the inhibitors directed toward hGM is desired in order to use them in cancer chemotherapy. We report on the rapid synthesis of D-mannose derivatives having one of the RS-. R(SO)- or R(SO(2))- groups at the alpha-anomeric position. Inhibitory properties of thirteen synthesized alpha-D-mannopyranosides were tested against the recombinant enzyme Drosophila melanogaster homolog of hGM (dGMIIb) and hLM (dLM408). Derivatives with the sulfonyl [R(SO(2))-] group exhibited inhibitory activities at the mM level toward both dGMIIb (IC(50) = 1.5-2.5 mM) and dLM408 (IC(50) = 1.0-2.0 mM). Among synthesized, only the benzylsulfonyl derivative showed selectivity toward dGMIIb. Its inhibitory activity was explained based on structural analysis of the built 3-D complexes of the enzyme with the docked compounds. (C) 2011 Elsevier Masson SAS. All rights reserved.
