Abstract: A series of sulfonamides incorporating the sulfanilamide (SA) scaffold were prepared. Reaction of the 4-amino moiety of SA with benzyl chlorides or substituted bromoacetophenones afforded the 4-mono-alkylated derivatives which were then reacted with 1,1,1-trifluoro-4-isobutoxybut-3-en-2-one leading to a series of 4-N,N-disubstituted SAs. The key intermediates were also reacted with ethoxycarbonyl isothiocyanate leading to thioureas or were cyclized in the presence of potassium cyanate/isothiocyanate to the corresponding imidazol-2(3H)-one/thiones. The new compounds were tested as inhibitors of four carbonic anhydrase (CA, EC 4.2.1.1) isoforms, the cytosolic CA I and II, and the transmembrane, tumor-associated CA IX and XII. These sulfonamides were ineffective CA I and II inhibitors but were nanomolar CA IX and XII inhibitors, making them of interest as clinical candidates for antitumor/antimetastasis applications.
