3-[[3-fluoro-5-(tetrahydro-4-methoxy-2H-pyran-4-yl)phenoxy]methyl]-1-[4-(methylsulfonyl)phenyl]-5-phenyl-1H-pyrazole is a dual inhibitor of Cox-2 (cyclooxygenase-2) and 5-LO (5-lipoxygenase) (IC50 of 50 nM and 3 nM, respectively). 3-[[3-fluoro-5-(tetrahydro-4-methoxy-2H-pyran-4-yl)phenoxy]methyl]-1-[4-(methylsulfonyl)phenyl]-5-phenyl-1H-pyrazole is selective for Cox-2 over Cox-1 by greater than 200-fold. Cox-2/5-LO inhibitors are also apoptosis-inducing agents and are potentially useful in prostate cancer chemotherapy. In the PC3 human carcinoma cell line, 3-[[3-fluoro-5-(tetrahydro-4-methoxy-2H-pyran-4-yl)phenoxy]methyl]-1-[4-(methylsulfonyl)phenyl]-5-phenyl-1H-pyrazole exhibits a 45% inhibition of proliferation at 100 μM, and in the LNCaP human carcinoma cell line, a IC50 value of 83 μM.
