  Synthesis and Anti-HCV Activity of 4-Hydroxyamino α-Pyranone Carboxamide Analogues

  摘要：

  High genetic variability in hepatitis C virus (HCV), emergence of drug resistant viruses and side effects demand the requirement for development of new scaffolds to show an alternate mechanism. Herein, we report discovery of new scaffold I based on 4-hydroxyamino alpha-pyranone carboxamide as promising anti-HCV agents. A comprehensive structure activity relationship (SAR) was explored with several newly synthesized compounds. In all promising compounds (17-19, 21-22, 24-25, and 49) with EC50 ranging 0.15 to 0.40 mu M, the aryl group at C-6 position of alpha-pyranone were unsubstituted. In particular, 25 demonstrated potential anti-HCV activity with EC50 of 0.18 mu M in cell based HCV replicon system with lower cytotoxicity (CC50 > 20 mu M) and provided a new scaffold for anti-HCV drug development. Further investigations, including biochemical characterization, are yet to be performed to elucidate its possible mode of action.

  Despite the availability of several methods for decarboxylation, this area remains exploratory and requires new development. Here, we report a highly efficient microwave-assisted hydrodecarboxylation of 4-(methylthio)-2-oxo-6-aryl-2H-pyran-3-carboxylic acids (1a-k) under basic condition to obtain 4-(methylthio)-6-aryl-2H-pyran-2-ones (2a-k) with >90% yield.

  Hepatitis C Virus exhibits high genetic diversity. The current treatment for genotype-1 with similar to 80% sustained virologic responses is a combination of pegylated interferon, ribavirin and boceprevir/telaprevir/simeprevir which is associated with several side effects and need close monitoring. Therefore, novel therapies are invited for safer and more efficient treatment. This study was designed for synthesis of new alpha-pyranone carboxamide analogs for evaluation of anti-HCV activity to delineate structure-activity relationship (SAR) and to identify anti-HCV determinant motif on this new scaffold. Forty four new alpha-pyranone carboxamide analogs were synthesized. Six potential anti-HCV candidates 11a (EC50 = 0.35 mu M), 11e (EC50 = 0.48 mu M), 12f (EC50 = 0.47 mu M), 12g (EC50 = 0.39 mu M), 12h (EC50 = 0.20 mu M) and 12j (EC50 = 0.25 mu M) with lower cytotoxicity (CC50 > 20 mu M) were discovered through cell based HCV replicon system. The activity profile of forty four new a-pyranone carboxamide analogs suggests the role of an aromatic motif in the B region to add a synergistic effect to NHOH motif at 4-position and revels an anti-HCV activity determinants motif under this scaffold. The biochemical assay against most promising HCV target protein 'NS3 protease and NS5B polymerase' showed no activity and open a scope to explore new mechanism inhibitor. (C) 2015 Elsevier Ltd.

  The pharmacophoric hybridization and computational design approach were applied to generate a novel series of alpha-pyrone analogs as plausible anti-malarial lead candidate. A putative active site in flexible loop close to wing-helix domain of PfRIO2 kinase was explored computationally to understand the molecular basis of ligand binding. All the synthesized molecules (3a-g) exhibited in vitro antimalarial activity. Oxidative stress induced by 3a-d were calculated and found to be significantly higher in case of 3b. Therefore, 3b, which shown most significant result was identified as promising lead for further SAR study to develop potent anti-malarials. (C) 2013 Elsevier Masson SAS. All rights reserved.
