  摘要：

  New [2',5'-bis-O-(tert-butyldimethylsilyl)-beta-D-ribofuranosyl]-3'-spiro-5"-(4"-amino-1",2"-oxathiole-2",2"-dioxide) (TSAO) derivatives substituted at the 4"-amino group of the spiro moiety with different carbonyl functionalities have been designed and synthesized. Various synthetic procedures, on the scarcely studied reactivity of the 3'-spiroaminooxathioledioxide moiety, have been explored. The compounds were evaluated for their inhibitory effect on both wild-type and TSAO-resistant HIV-1 strains, in cell culture. The presence of a methyl ester (10) or amide groups (12) at the 4"-position conferred the highest anti-HIV-1 activity, while the free oxalyl acid derivative (11) was 10- to 20-fold less active against the virus. In contrast, the presence at this position of (un)substituted ureido or acyl groups markedly diminished or annihilated the anti-HIV-1 activity. Surprisingly, some of the target compounds also showed inhibition of human cytomegalovirus (HCMV) replication at subtoxic concentrations. This has never been observed previously for TSAO derivatives. In particular, compound 26 represents the first TSAO derivative with dual anti-HIV-1 and -HCMV activity.

• Novel TSAO Derivatives Modified at Positions 3′ and 4′ Of the Spiro Moiety

  We have explored the introduction of different functional groups at positions 3 " and 4 " of the spiro moiety of TSAO-T. Alkylation of this spiro moiety afforded mixtures of N and/or C-alkylated derivatives, while acylation occurs, exclusively, on the amino group. Position 3 " has been selectively functionalized by halogenation followed by Stille-cross coupling reaction with organostannanes under a variety of experimental conditions.

  A "second generation" of TSAO molecules directed against TSAO-resistant strains have been prepared. The presence of two neighboring carbonyl groups at the 4 " position of the 3'-spiro moiety seems to be important for the anti-HIV-1 activity against both wild type and TSAO-resistant strains. NMR conformational studies in solution and theoretical calculations of the novel compounds have also been carried out.
