Bottom Line: All compounds containing P-C-C-triazole or P-C-C-CH2-triazole moieties exist in single conformations in which the diethoxyphosphoryl and substituted 1,2,3-triazolyl or substituted (1,2,3-triazolyl)methyl groups are oriented anti.None of the compounds were endowed with antiviral activity.They were not cytostatic at 100 μM.

ABSTRACT

Abstract: A series of diethyl 2-(4,5-dimethoxycarbonyl-1H-1,2,3-triazol-1-yl)alkylphosphonates was synthesised from ω-azidoalkylphosphonates and dimethyl acetylenedicarboxylate and was further transformed into the respective diamides, dihydrazides, and 5,6-dihydro-1H-[1,2,3]triazolo[4,5-d]pyridazine-4,7-diones as phosphonate analogues of acyclic nucleosides having nucleobases replaced with substituted 1,2,3-triazoles. All compounds containing P-C-C-triazole or P-C-C-CH2-triazole moieties exist in single conformations in which the diethoxyphosphoryl and substituted 1,2,3-triazolyl or substituted (1,2,3-triazolyl)methyl groups are oriented anti. All phosphonates were evaluated in vitro for activity against a variety of DNA and RNA viruses. None of the compounds were endowed with antiviral activity. They were not cytostatic at 100 μM.

Mentions: Furthermore, preliminary structure–activity relationship evaluation of 1,2,3-triazole nucleoside phosphonates 3 and 4 suggested that this scaffold could be further optimised to afford selective inhibitors of HCV replication (Fig. 4) [28].Fig. 4
