5-Acetyl-2-arylbenzimidazoles as antiviral agents. Part 4
摘要:
Within a project aimed at discovering new Flaviviridae inhibitors, new variously substituted 2-phenylbenzimidazoles were synthesized and evaluated in cell-based assays for cytotoxicity and antiviral activity against viruses representatives of the three genera of the Flaviviridae family, i.e.: Pestivirus (BVDV), Flavivirus (YFV) and Hepacivirus (HCV). Title compounds were also tested against RNA viruses representative of other single-stranded, positive-sense (ssRNA(+)) negative-sense (RNA(-)), or double-stranded (dsRNA) genomes, as well as against representatives of two DNA virus families.Nine compounds showed activity against BVDV (EC50 = 0.8-8.0 mu M), compound 31 being the most potent (EC50 = 0.80 mu M) and selective (SI = CC50/EC50 = >100). When tested in an HCV replicon assay, compound 31 resulted again the most potent, displaying an EC50 value of 1.11 mu M and an SI of 100. Besides inhibiting BVDV, two compounds (35 and 38) showed a moderate activity also against YFV (EC50 = 13 mu M). Interestingly, 35 was moderately active also against RSV (EC50 = 25 mu M).

compounds, sulfoximines and benzimidazoles, were ingeniously prepared from oxadiazolines via nitrene intermediates by photocatalytic N-O/C-N bond cleavages. The synthesis of sulfoximines was realized through intermolecular N-S bond formation between nitrene intermediates and sulfoxides, whereas benzimidazoles were obtainedvia intramolecular aromatic substitution of the nitrene to the tethered aryl substituent

CuI/l-proline catalyzed coupling of aqueous ammonia with 2-iodoacetanilides and 2-iodophenylcarbamates affords the arylamination products at roomtemperature, which undergo in situ additive cyclization under acidic conditions or heating to give substituted 1H-benzimidazoles and 1,3-dihydrobenzimidazol-2-ones, respectively. A wide range of functional groups including ketone, nitro, iodo, bromo, and
