The Fight against the Influenza A Virus H1N1: Synthesis, Molecular Modeling, and Biological Evaluation of Benzofurazan Derivatives as Viral RNA Polymerase Inhibitors
The influenzaRNApolymerase 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 againstinfluenzavirus A/WSN/33 (H1N1). Most of the new derivatives were found to act by inhibiting the viralRNApolymerase complex through disruption of the complex formed
A comparative study of the self-immolation of para-aminobenzylalcohol and hemithioaminal-based linkers in the context of protease-sensitive fluorogenic probes
This study focuses on the disassembly-behavior of self-immolative pro-fluorescent linkers under physiological conditions and through an enzyme-initiated domino reaction. The targeted linkers are based on para-aminobenzylalcohol (PABA) or hemithioaminal derivatives of para-carboxybenzaldehyde or glyoxilic acid. We found that a fine tuning of the kinetic properties could be obtained through the modulation of the linker structure, giving either a fast signal response or free-adaptable systems suitable for the design of protease-sensitive fluorogenic probes or prodrug systems.

The invention relates generally to pyrrolobenzodiazepine monomer and dimer prodrugs having a glutathione-activated disulfide prodrug moiety, a DT-diaphorase-activated quinone prodrug moiety or a reactive oxygen species-activated aryl boronic acid or aryl boronic ester prodrug moiety. The invention further relates to pyrrolobenzodiazepine prodrug dimer-antibody conjugates.
Amidation of Aldehydes and Alcohols through α-Iminonitriles and a Sequential Oxidative Three-Component Strecker Reaction/Thio-Michael Addition/Alumina-Promoted Hydrolysis Process to Access β-Mercaptoamides from Aldehydes, Amines, and Thiols
hydrolysis conditions for converting α‐iminonitriles into carboxamides have been developed. In combination with the oxidative three‐component Strecker reaction, the one‐pot direct amidation of aldehydes and alcohols is reported. Subsequently, an Yb(OTf)3‐catalyzed Michael addition of thiols to α,β‐unsaturated α‐iminonitriles is reported for the synthesis of β‐mercapto‐α‐iminonitriles. The successful integration
