Pyrazole carboxylic acid derivatives of 5-amino-1,3,4-thiadiazole-2-sulfonamide (inhibitor 1) were synthesized from ethyl 3-(chlorocarbonyl)-1-(3-nitrophenyl)-5-phenyl-1H-pyrazole-4-carboxylate compound. The inhibitory effects of inhibitor 1, acetazolamide (AAZ) and of 11 newly synthesized amides (5a–b, 6, 7a–g, and 8) on hydratase and esterase activities of carbonic anhydrase isoenzymes (hCA-I and hCA-II) have been studied in vitro. The comparison of newly synthesized amides to inhibitor 1 and to AAZ indicated that the new derivatives inhibit CA isoenzymes and they are more potent inhibitors than the parent inhibitor 1 and AAZ.
Sulfonamides are the best-known inhibitors of carbonic anhydrase enzyme, currently used for the treatment of glaucoma in clinical medicine.Pyrazole derivatives which contain sulfonamide group have more inhibition effects to CA-I and CA-II isoenzymes.Figure optionsDownload as PowerPoint slide
