Compounds of Formula I are useful for inhibiting Raf kinase and for treating disorders mediated thereby. Methods of using compounds of Formula I, and stereoisomers, geometric isomers, tautomers, solvates and pharmaceutically acceptable salts thereof, for in vitro, in situ, and in vivo diagnosis, prevention or treatment of such disorders in mammalian cells, or associated pathological conditions are disclosed.
Under transition-metal-free conditions, calcium carbide was used as the acetylide source to react with a wide range of N-tosylhydrazones derived from aldehydes or ketones, affording various substituted pyrazoles in good...
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.
