synthesized derivatives were evaluated for anti-inflammatory activity but none was found to be active. Subsequently a random biological screening was carried out. Interestingly many of them were found to be potent α-glucosidase inhibitors in vitro. All the structures of synthesized derivatives were deduced through 1H-NMR, FAB-MS, HR-MS, FT-IR analysis. The single-crystal X-ray structures of compounds

N-[[4-[5-(4-methylphenyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl]phenyl]-sulfonyl]propanamide and pharmaceutically acceptable salts thereof are useful prodrugs of the selective COX-2 inhibitory drug celecoxib, which can be administrated to a subject by any suitable route.
The present invention provides NO-releasing NONOate(nitrogen bound)sulfonamide-linked-coxib anti-cancer agents, having the structure of Formula (I):

, and Z are as defined in the detailed description; pharmaceutical compositions comprising at least one compound of Formula (I); and methods useful for healing wounds, preventing and treating cancer, or treating actinic keratosis, cystic fibrosis or acne, using a compound of Formula (I).
A pharmaceutical composition that is substantially free of water comprises at least one orally deliverable dosage unit comprising a therapeutically effective amount of a sulfonamide prodrug and, where the prodrug is readily degradable ex vivo, has means to inhibit such degradation prior to oral administration. Illustratively the prodrug is parecoxib or a water-soluble salt thereof, and the composition has means to inhibit conversion of the parecoxib to valdecoxib. A method of treating or preventing a COX-2 mediated disorder in a subject comprises (a) dissolving at least one dosage unit of such a composition in a pharmaceutically acceptable aqueous vehicle to form a solution, and (b) orally administering the solution to the subject before substantial precipitation of insoluble matter occurs in the solution.
