Transmissible spongiform encephalopathies (TSEs) are thought to arise from aggregation of a protease resistant protein denoted PrPSc, which is a misfolded isoform of the normal cellular prion protein PrPC. Using virtual high-throughput screening we have selected structures analogous to acridine, 2-methyquinoline and 2-phenylquinazoline as potential therapeutic candidates for the treatment of TSEs. From the synthesis and screening of constructed libraries we have shown that an electron-rich aromatic ring attached through an amine linker to the position para to the ring nitrogen is beneficial to both binding to PrPC and the suppression of PrPSc accumulation for acridine and 2-methylquinoline analogues. 2-Phenylquinazoline analogues appear to utilise a different mode of action by binding at a different location and/or pose. We report IC(50)s in the nanomolar range. (c) 2006 Elsevier Masson SAS. All rights reserved.

A method of increasing survival of viral infected honeybees, reducing viral load or protecting the honeybees from death, wherein said virus is a ssRNA virus, comprising administering to the honeybees an antiviral effective amount of an acridine derivative.
Synthesis of Pyridine<i>N</i>-Oxide-BF<sub>2</sub>CF<sub>3</sub>Complexes and Their Fluorescence Properties
PyridineN‐oxide–BF2CF3 and –BF2C2F5 complexes and their derivatives were synthesized. Most of the complexes show fluorescence both in solution and in the solid state. By expanding the π‐conjugated skeleton, the color of the fluorescence could be changed dramatically. A fluorophore with a high solvent dependency could also be produced. Since such compounds can be synthesized on a gram scale in high
