Human Golgi α-mannosidase II (hGM) is a pharmaceutical target for the design of inhibitors with anti-tumor activity. Nanomolar inhibitors of hGM exhibit unwanted co-inhibition of the human lysosomal α-mannosidase (hLM). Hence, improving specificity of the

A number of novel, aryl and aralkyl D-mannopyranosides and 1-thio-D-mannopyranosides were synthesized for evaluation of insulin-like and insulin-antagonistic properties.The substituted-phenyl α-D-mannopyranosides were prepared by the general procedure of Helferich and Schmitz-Hillebrecht, the substituted-phenyl 1-thio-α-D-mannopyranosides by a method corresponding to the Michael synthesis of aromatic glycosides, and the aralkyl 1-thio-α-D-mannopyranosides by aralkylation of 2,3,4,6-tetra-O-acetyl-1-thio-α-D-mannopyranose 15 and subsequent O-deacetylation.Compound (15) was obtained by basic cleavage of the amidino group in 2-S-(tetra)-O-acetyl-α-D-mannopyranosyl)-2-thiopseudourea hydrobromide, the product of the reaction of tetra-O-acetyl-α-D-mannosyl bromide with thiourea.Benzyl 1-thio-β-D-mannopyranoside, obtained by reaction of the sodium salt of 1-thio-β-D-mannopyranose with α-bromotoluene, and benzyl 1-thio-α-L-mannopyranoside were also synthesized, in order to asses the stereospecificity of the biological activites measured.
