title: Synthesis of substituted-phenyl-1,2,4-triazol-3-thione analogues with modified D-glucopyranosyl residues and their antiproliferative activities.
abstract: A series of D-glucopyranosyl-1,2,4-triazole-3-thione derivatives 1a-1d were synthesized by the reaction of 1,2,4-triazole-3-thione Schiff bases 5a-5d with 2,3,4,6-tetra-O-acetyl-sigma-D-glucopyranosyl bromide. We demonstrate the conversion of 2 to 5, without the necessity of purification of both oxadiazole and triazole intermediates to afford the compounds 5. Their structures were confirmed by standard studies of (1)H NMR, IR, MS and elemental analysis. Analogues 5 and 1 have shown cytotoxic activity against human MCF-7 and Bel-7402 malignant cell lines.
