Synthesis and investigation of inhibition effect of fluorinated sulfonamide derivatives on carbonic anhydrase
摘要:
Series of perfluoroalkanesulfonamides 1, sodium salt of perfluoroalkanesulfonamides 2 and poly-fluoroalkanesulfonamides 3 derivatives were synthesized and characterized by H-1 NMR, C-13 NMR, F-19 NMR, IR and HRMS. Inhibition effects of these compounds on bovine carbonic anhydrase (bCA) and human carbonic anhydrase isoenzyme II (hCA) have been investigated. Comparing IC50 values of the synthesized molecules 1, 2 and 3, it has been found that compound 2b is a more potent inhibitor than acetazolamide on hCA. Moreover 2b does not present cellular toxicity on sheep red globules. (C) 2009 Elsevier Masson SAS. All rights reserved.

describes a synthesis of symmetric and dissymmetric bis[(perfluoroalkane)-sulfonyl]imides by the reaction of the sodium salt of perfluoroalkanesulfonamide RFSO2NH−Na+ (RF = C4F9, C6F13, C8F17) with hexamethyldisilazane and perfluoroalkanesulfonylfluoride RFSO2F (RF = C4F9, C6F13, C8F17). They are obtained, in two steps, in moderate overall yield. Moreover, this paper provides a study of their inhibition on
This study describes a newsynthesis of F-alkanesulfonyl ureas by reaction of the sodium salt of perfluoroalkane sulfonamide (RF = C4F9, C6F13) with some isocyanates in anhydrous THF. The perfluorinated sulfonylureas are obtained, in one step, from moderate to good yields.
