The fight against the influenza A virus H1N1: Synthesis, molecular modeling, and biological evaluation of benzofurazan derivatives as viral RNA polymerase inhibitors

The influenza RNA polymerase complex, which consists of the three subunits PA, PB1, and PB2, is a promising target for the development of new antiviral drugs. A large library of benzofurazan compounds was synthesized and assayed against influenza virus A/WSN/33 (H1N1). Most of the new derivatives were found to act by inhibiting the viral RNA polymerase complex through disruption of the complex formed between subunits PA and PB1. Docking studies were also performed to elucidate the binding mode of benzofurazans within the PB1 binding site in PA and to identify amino acids involved in their mechanism of action. The predicted binding pose is fully consistent with the biological data and lays the foundation for the rational development of more effective PA-PB1 inhibitors. In the fight against influenza virus A/WSN/33 (H1N1), the PA-PB1 protein-protein interaction is emerging as a new drug target. To identify small molecules able to inhibit the viral RNA polymerase complex, the benzofurazan scaffold was explored by synthesizing a large library of derivatives. Some compounds showed high anti-H1N1 activity and emerged as effective inhibitors of the PA-PB1 interaction, with IC50 values in the micromolar range. Copyright

6,6-Fused heterocyclic ureas as highly potent TRPV1 antagonists

A series of N-[{2-(4-methylpiperidin-1-yl)-6-(trifluoromethyl)-pyridin-3-yl}methyl] N?-(6,6-fused heterocyclic) ureas have been investigated as hTRPV1 antagonists. Among them, compound 15 showed highly potent TRPV1 antagonism to capsaicin, with Ki(ant) = 0.2 nM, as well as antagonism to other activators, and it was efficacious in a pain model. A docking study of 15 with our hTRPV1 homology model indicates that there is crucial hydrogen bonding between the ring nitrogen and the receptor, contributing to its potency.

Developing structure-activity relationships from an HTS hit for inhibition of the Cks1-Skp2 protein-protein interaction

Structure-activity relationships have been developed around 5-bromo-8-toluylsulfonamidoquinoline 1 a hit compound in an assay for the interaction of the E3 ligase Skp2 with Cks1, part of the SCF ligase complex. Disruption of this protein-protein interaction results in higher levels of CDK inhibitor p27, which can act as a tumor suppressor. The results of the SAR developed highlight the relationship between the sulfonamide and quinoline nitrogen, while also suggesting that an aryl substituent at the 5-position of the quinoline ring contributes to the potency in the interaction assay. Compounds showing potency in the interaction assay result in greater levels of p27 and have been shown to inhibit cell growth of two p27 sensitive tumor cell lines.
