ACYCLOVIR ANALOGUES -- 1,2,4-TRIAZOLO[1,5-A]PYRIMIDINES -- TMSOTF
Аннотация: New acyclovir analogues were obtained by reaction of 1,2,4-triazolo[1,5-a]pyrimidin-7-ones 4a–i with (2-acetoxyethoxy)methyl acetate 5 in the presence of trimethylsilyl trifluoromethanesulfonate (TMSOTf) as catalyst (Vorbrüggen procedure). Coupling between compounds 4a–f and 5 led to a mixture of N3- and N4-isomers 6 and 7, respectively. On the contrary, the reaction of compounds 4g–i with 5 proceeded selectively with formation of N3-isomers only. It was found that the ratio of 6a–f and 7a–f depends on the presence or the absence of N,O-bis(trimethylsilyl)acetamide (BSA). Glycosylated products 6a–f and 7a–f underwent reversible isomerization under TMSOTf treatment. The ratio of glycosylated products of the coupling reaction between 4 and 5 was thermodynamically controlled. A similar reaction occurred if ZnCl2 was chosen as a catalyst, although lower yields of the acyclic analogues of nucleosides were observed. The glycosylation of other purines (adenine and guanine) can be achieved via the non-BSA modification of the Vorbrüggen proced

ACYCLOVIR
Аннотация: New analogues of acyclovir have been prepared by reacting 1,2,4 -triazolo[1,5-a]pyrimidin-7-ones 1а-i and (2-acetoxyethoxy)methyl acetate 2 in the presence of trimethylsilyl trifluoromethanesulfonate as a catalyst. The interaction between the compounds 1а-е and 2 has led to a mixture of N3 and N4 isomers. In contrast, the reaction of compounds 1g-i and 2 proceeded selectively to form N3 isomers. In the case of compounds 1a-c the predominant product is the one with the acyclic moiety in azine ring (N4 isomer). Interaction between 1d-f and 2 has led to mixtures comprising mainly N3 isomer. It has been found that the ratio of glycosylation products 1 and 2 are thermodynamically controlled. The structure of the obtained compounds has been proved by 1Н, 13С, two-dimensional 1Н-13С NMR spectroscopy and X-ray analysis.

ANTIVIRAL ACTIVITY -- BENZIMIDAZOLES -- FLUORINATED COMPOUNDS -- NUCLEOSIDE PHOSPHORYLASES -- NUCLEOSIDES -- TRANSGLYCOSYLATION REACTION
Аннотация: Using the enzymatic transglycosylation reaction β-d-ribo- and 2′-deoxyribofuranosides of 2-amino-5,6-difluorobenzimidazole nucleosides have been synthesized. 2-Amino-5,6-difluoro-benzimidazole riboside proved to exhibit a selective antiviral activity (selectivity index >32) against a wild strain of the herpes simplex virus type 1, as well as towards virus strains that are resistant to acyclovir, cidofovir, and foscarnet. We believe that this compound might be used for treatment of herpes infections in those cases, when acyclovir is not efficient.

6-CHLOROPURINE -- ANTIVIRAL ACTIVITY -- HERPES SIMPLEX VIRUS TYPE 1
Аннотация: A method for the synthesis of novel purine conjugates with 7,8-difluoro-3-methyl-3,4-dihydro-2H-1,4-benzoxazine containing fragments of ω-amino acids with different lengths of the polymethylene chain as a linker has been developed. It was found in experiments in vitro that the obtained compounds are active against the herpes simplex virus type 1, including the acyclovir-resistant strain.

Аннотация: New purine derivatives containing a nido-carborane fragment were synthesized by nucleophilic substitution of chlorine atom in 6-chloropurine and 2-amino-6-chloropurine under the action of nido-carborane-containing amines. Compounds with significant activity against the acyclovir-resistant strain of herpes simplex virus type 1, as well as with moderate activity against influenza viruses A and B, were discovered for the first time among the synthesized nido-carboranyl derivatives of purine.
