| Sumario: | Herein we report the design, synthesis and characterization of novel 1,2,4-triazole d-ribose derivatives, as well as their synthetic precursors. The antitumoral activity against T cell lymphoma cell line of these products was studied. Structures containing a 1,2,4-triazolic ring linked by sulfur to the carbohydrate moiety showed a moderate antiproliferative activity. The presence of the second heterocyclic ring did not show significant changes in their biological activity. Meanwhile, structures with 3-thiobenzyl-5-substituted-1,2, 4-triazole ring linked by nitrogen leads to compounds with a biphasic behavior, stimulating cell proliferation at low concentrations and inhibiting it at higher ones. An increment in the polarity was associated with a decrease in the activity of the evaluated compounds. A preliminary antitumoral screening pointed the 1,2,4-triazolic structures linked to protected sugars as promising leaders for further studies. © 2011 Elsevier Masson SAS. All rights reserved. |
