Abstract

Novel 2-(substituted benzyl)-3,5,6,7-tetrahydro-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidin-4-ones and 4-fluoro-N-(4-oxo-3,5,6,7-tetrahydro-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidin-2-yl)benzamide compounds, a method of synthesizing said compounds, a pharmaceutical composition comprising said compounds and a suitable carrier, and a method of using the compounds. The 2-(substituted benzyl)-3,5,6,7-tetrahydro-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidin-4-ones and 4-fluoro-N-(4-oxo-3,5,6,7-tetrahydro-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidin-2-yl)benzamide compounds, identified as COX-2 inhibitors, are useful as anti-inflammatory and pain agents.

Claims (8)

1. A compound having the formula I:

or a pharmaceutically acceptable salt, ester, stereoisomer, or solvate thereof, wherein:

R is —NHCOPhenyl wherein the phenyl in the —NHCOPhenyl is substituted with a fluorine.

2. A pharmaceutically acceptable composition comprising a therapeutically effective amount of the compound of claim 1 and a pharmaceutically acceptable carrier.

3. A compound that is:

4-Fluoro-N-(4-oxo-3,5,6,7-tetrahydro-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidin-2-yl)benzamide (9),

or a pharmaceutically acceptable salt, ester, stereoisomer, or solvate thereof.

4. A pharmaceutically acceptable composition comprising a therapeutically effective amount of the compound of claim 3 and a pharmaceutically acceptable carrier.
