title: Carbonic anhydrase inhibitors: Selective inhibition of the extracellular, tumor-associated isoforms IX and XII over isozymes I and II with glycosyl-thioureido-sulfonamides.
abstract: A series of glycosyl-thioureido sulfonamides incorporating glucosamine, galactosamine, and mannosamine tails, and sulfanilamide, halogenosulfanilamide, and metanilamide heads was synthesized. Many of the new compounds showed micromolar-submicromolar affinity for the inhibition of the cytosolic isoforms I and II of the metalloenzyme carbonic anhydrase (CA, EC 4.2.1.1), but low nanomolar binding to the tumor-associated isozymes, CA IX and XII. The selectivity ratios for the inhibition of the tumor-associated over the cytosolic isozymes were in the range of 107-955 for the most selective such inhibitors.
