  摘要：

  A general simple route for the synthesis of triazolo[4,5-g]quinolines and pyrido[2,3-g]quinoxalines is described. The heterocycles obtained were fully characterised by their spectroscopical properties. A revision of the nitration of the 2,3-dichloroacetanilide is also discussed, since it afforded the request nitro derivative to build up the key intermediate 6,7-diaminoquinolines.

  A series of twelve novel pyrido[2,3-g]quinoxalinones (3-14), variously substituted at the C-3 position, was synthesized, structurally determined and submitted to a preliminary in vitro evaluation for antibacterial, anticandida and anticancer activities. Results of the antimicrobial screening showed that all compounds, with the exception of 6, 11 and 12, exhibited interesting activity against all strains tested; while compound 10 was found to have encouraging in vitro anticancer activity at a concentration of 10(-4) M.

• Synthesis, cytotoxicity and antiviral evaluation of new series of imidazo[4,5-g]quinoline and pyrido[2,3-g]quinoxalinone derivatives

  Linear aromatic N-tricyclic compounds with promising antiviral activity and minimal cytotoxicity were prepared and analyzed in the last years. Specifically, the pyrido[2,3-g]quinoxalinone nucleus was found endowed with high potency against several pathogenic RNA viruses as etiological agents of important veterinary and human pathologies. Following our research program on new antiviral agents we have designed, synthesized and assayed new series of imidazo[4,5-g]quinoline and pyrido[2,3-g]quinoxalinone derivatives. Lead compounds 1-4 were further modified to enhance their antiviral activity and reduce their cytotoxicity. Thus, different substituents were introduced on N atom at position 1 or the 0 atom at position 2 of the leads; contextually, several groups were inserted on the nitrogen atom at position 7 of diaminoquinoline intermediates. Title compounds were tested in cell-based assays for cytotoxicity and antiviral activity against RNA virus families containing single-stranded (either positive-sense (ssRNA+) or negative-sense (ssRNA-)), and double-stranded genomes (dsRNA), and against two representatives of DNA virus families. Some derivatives emerged as potential leads for further development as antiviral agents against some viruses of public health significance, such as RSV, Reo, BVDV and HCV. Particularly, compounds 4, 11b, 11c, 13c, 15a,18 and 21 resulted active against BVDV at concentrations ranging from 1.3 to 5 mu M. Compound 21 was also evaluated for its activity on the BVDV RdRp. Compound 4 was also tested as potential anti-HCV compound in a subgenomic replication assay. Molecular simulation results provided a molecular rationale for the anti-BVDV activity of these compounds.
