[0129] Compound preparation

[0130] The compounds of the present invention can be prepared as free bases or pharmaceutically acceptable salts thereof by the following methods. In the following description of such methods, it is understood that suitable protecting groups, where appropriate, will be added and subsequently removed from various reactants and intermediates in a manner readily understood by those skilled in the art of organic synthesis. Conventional methods of using such protecting groups as well as examples of suitable protecting groups are eg described in Protective Groups in Organic Synthesis by T.W. Greene, P.G.M Wutz, 3rd Edition, Wiley-Interscience, New York, 1999.

[0131] general method

[0132] All solvents used were of analytical grade, and commercially available anhydrous solvents were routinely used for reactions. Starting materials used were obtained from commercial sources or were prepared according to literature procedures. Room temperature means...

Abstract

The present invention relates to bis(sulfonamide) compounds and pharmaceutically acceptable salts thereof. The present invention also relates to pharmaceutical compositions comprising these compounds and to their use as a medicament for the treatment and / or prevention of a disease, disorder or condition in which modulation of microsomal prostaglandin E synthase-1 activity is beneficial, such as pain, inflammation and cancer.

Description

technical field [0001] The present invention relates to bis(sulfonamide) compounds and pharmaceutically acceptable salts thereof. The present invention also relates to pharmaceutical compositions comprising these compounds, and their use in the treatment and / or prevention of diseases, disorders or conditions in which modulation of microsomal prostaglandin E synthase-1 activity is beneficial, such as pain, inflammation and cancer, etc. use of the drug. Background technique [0002] Regulation of prostaglandin metabolism is central to current anti-inflammatory treatments. NSAIDs and COX-2 inhibitors block the activity of cyclooxygenase and its ability to convert arachidonic acid to prostaglandin H2 (PGH2). PGH2 can then be metabolized to the corresponding biologically active PGs, namely PGI2, thromboxane (Tx)A2, PGD2, PGF2α and PGE2, via terminal prostaglandin synthase. A combination of pharmacological, genetic, and neutralizing antibody approaches suggests the importance o...
