N-acetyl-D-mannosamine analogues as potential inhibitors of sialic acid biosynthesis

A F Hadfield et al. J Pharm Sci. 1983 Jul.

Abstract

The 1,3,6-tri-O-acetyl and 1,3,6-tri-O-acetyl-4-O-mesyl analogues of N-acetyl-D-mannosamine and the corresponding N-trifluoroacetyl derivative have been synthesized, and their effects on the proliferation of Friend erythroleukemia cells in culture have been evaluated. The acetamido series showed a dependency on the 4-substituent for optimum cytotoxicity while the trifluoroacetamido series did not. Thus, the 1,3,4,6-tetra-O-acetyl and 1,3,6-tri-O-acetyl-4-O-mesyl analogues of N-acetyl-D-mannosamine were 10-fold and 42-fold more active, respectively, than 2-acetamido-1,3,6-tri-O-acetyl-2-deoxy-alpha-D-mannopyranose as inhibitors of cellular replication. The corresponding trifluoroacetamido analogues were essentially equiactive and had a potency equivalent to that of the 4-O-mesyl derivative in the acetamido series.
