  Synthesis of New 1,2,4-Triazole-5-Thiones and Their Thioglycoside Derivatives as Potential Antibacterial Agents

  摘要：

  The glycosylation of 1,2,4-triazole-5-thiones has been performed with peracetylated -pyranosyl bromide in the presence of potassium carbonate. The synthesized compounds were tested for their antimicrobial activity against bacterial (Gram-negative and Gram-positive) and yeasts strains in vitro. The synthetic compounds showed different inhibition zones against tested bacterial and yeasts strains. Among them, compounds which possessed 2-furyl and p-bromophenyl moieties showed the best results against Acinetobacter calcoaceticus ATCC 23055.

  Under microwave irradiation (MWI), 4-phenyl-5-substituted-4H-1,2,4-triazole-3-thiol derivatives 7 and 8 were synthesized in a good yield by intramolecular cyclization of the aroyl phenyl thiosemicarbazides 5 and 6. The respective triazolylglycosides (Str-glycosides) 12-17 were obtained by reaction of triazoles 7 and 8 with glycosyl halides 9-11 in dry acetone in the presence of potassium carbonate as base under both conventional and MWI conditions. Alkylation of 7 and 8 with haloalchols 18-20 in boiling ethanolic solution containing sodium ethoxide as a base gave the corresponding alkylated analogs 21-26. MWI conditions led to higher yield in shorter reaction time than the conventional method. Treatment of 26 with tosyl chloride gave the unexpected product 29 and not 27 or 28. Oxidation of 26 with sodium metaperiodate afforded triazole 8 and not the aldehyde 30. Attempted glycosylation and alkylation of the phenolic OH group in triazole 8 were unsuccessful; this was proved by theoretical calculations using the AM1 semi-empirical method.
