Reaction of 1-(S)-[3-hydroxy-2-(phosphonomethoxy)propyl]-5-azacytosine (1) with dicyclohexylcarbodiimide and N,N,-dicyclohexyl-4-morpholinocarboxamidine in dimethylformamide at elevated temperature afforded the corresponding cyclic phosphonate 2, that is, 1-{[(5S)-2-hydroxy-2-oxido-1,4,2-dioxaphosphinan-5-yl]methyl}-5-azacytosine. Compound 2 exerts strong in vitro activity against DNA viruses, comparable with activity of parent compound 1. Transformation of 2 to its tetrabutylammonium salt followed by reaction with alkyl or acyloxyalkyl halogenides enabled us to prepare a series of structurally diverse ester prodrugs: alkyl (octadecyl), alkenyl (erucyl), alkoxyalkyl (hexadecyloxyethyl), and acyloxyalkyl (pivaloyloxymethyl) (3-6). The introduction of an alkyl, alkoxyalkyl, or acyloxyalkyl ester group to the molecule resulted in an increase of antiviral activity; the most active compound was found to be the hexadecyloxyethyl ester 5. The relative configuration of the diastereoisomer trans-6 was determined using H,H-NOESY NMR.

D000998 Antiviral Agents Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly.

D012190 Retroviridae Family of RNA viruses that infects birds and mammals and encodes the enzyme reverse transcriptase. The family contains seven genera: DELTARETROVIRUS; LENTIVIRUS; RETROVIRUSES TYPE B, MAMMALIAN; ALPHARETROVIRUS; GAMMARETROVIRUS; RETROVIRUSES TYPE D; and SPUMAVIRUS. A key feature of retrovirus biology is the synthesis of a DNA copy of the genome which is integrated into cellular DNA. After integration it is sometimes not expressed but maintained in a latent state (PROVIRUSES).
