Application

4′-(Methylsulfonyl)acetophenone may be used in the synthesis of:
  • 3-(4-Methylsulfonylphenyl)-4-phenyl-2(5H)-furanone with potent apoptosis-inducing ability.
  • Bromo-4-methylsulfonylacetophenone, an intermediate for preparing DL-threo-2-dichloroacetamido-1-(4-methylsulfonylphenyl)-1,3-propanediol.
  • 1-N-Substituted-3,5-diphenyl-2-pyrazoline derivatives, which show promising anti-inflammatory activity.

The cyclooxygenase-2 (COX-2) inhibitor celecoxib is thought to act as a chemopreventive agent by sensitizing cancer cells to apoptotic signals. Other COX-2 inhibitors, such as rofecoxib, are two orders of magnitude less potent than celecoxib at inducing apoptosis. The molecular

Eighteen new 1-N-substituted-3,5-diphenyl-2-pyrazoline derivatives have been synthesized and cyclooxygenase (COX-1 and COX-2) inhibitory activities have been evaluated. The results of these biological assays showed that all of new derivatives are not endowed with improved anti-inflammatory activity against COX-1, but some
