An efficient Cu-catalyzed cascade reaction involving N–O bond cleavage and C–C/C–N/N–N bond formations is developed to afford various 1,3- and 1,3,4-substituted pyrazoles.
Described are coelenterazine analogues, methods for making the analogues, kits comprising the analogues, and methods of using the compounds for the detection of luminescence in luciferase-based assays.

This invention relates to novel pyrazole derivatives that are found to be potent modulators of potassium channels and, as such, are valuable candidates for the treatment of diseases or disorders as diverse as those which are responsive to the modulation of potassium channels.
The invention provides compounds that can efficiently and specifically inhibit bacterial toxins, such as inhibit the lethal factor (LF) protease activity of anthrax toxin and/or botulinum neurotoxin type A. The invention also provides methods for inhibiting proteases, such as lethal factor protease, as well as methods for treating bacterial infections, such as anthrax and botulinum.
