New series of sulfonamides containing amino acid moiety act as effective and selective inhibitors of tumor-associated carbonic anhydrase XII
摘要:
New benzenesulfonamides incorporating water solubilizing moieties were synthesized using N-alpha-acetyl-L-lysine or gamma-aminobutyric acid as scaffolds followed by the conversion of their terminal amino group to the guanidine one. Their inhibition activity was assessed by determining their K(I)s values against the human (h) carbonic anhydrase (CA, EC 4.2.1.1) isoforms hCA I, II, IX and XII. Some of these compounds were medium potency inhibitors of the cytosolic (CA I, II) and transmembrane (CA IX) isoforms and highly effective, nanomolar inhibitors of the second transmembrane isoform hCA XII. Some of these sulfonamides possessing good selectivity inhibition for the tumor-associated CA XII isoform over the cytosolic and physiologically dominant isoforms CA I and II may be used as tools to develop new anticancer agents.
Sulfonamides with Potent Inhibitory Action and Selectivity against the α-Carbonic Anhydrase from Vibrio cholerae
摘要:
By using N-alpha-acetyl-L-lysine or GABA scaffolds and the conversion of the terminal amino group to the guanidine one, benzenesulfonamides incorporating water solubilizing moieties were synthesized. The new compounds were medium potency inhibitors of the cytosolic carbonic anhydrase (CA, EC 4.2.1.1) isoforms I and II, and highly effective, nanomolar inhibitors of the pathogenic bacterial alpha-CA from Vibrio cholerae. These sulfonamides possess good selectivity for inhibiting the bacterial over the mammalian isoforms and may be used as tools to understand the role of bacterial CAs in pathogenesis.
