Abstract:
Isoquinolinesulfonamides inhibit human carbonic anhydrases (hCAs) and display selectivity toward therapeutically relevant isozymes. The crystal structure of hCA II in complex with 6,7-dimethoxy-1-methyl-1,2,3,4-tetrahydroisoquinolin-2-ylsulfonamide revealed unusual inhibitor binding. Structural analyses allowed for discerning the fine details of the inhibitor binding mode to the active site, thus providing clues for the future design of even more selective inhibitors for druggable isoforms such as the cancer associated hCA IX and neuronal hCA VII.

Phase II Reactions: Miscellaneous Conjugation Reactions
A key example involves the conjugation of cyanide ions, which impair cellular respiration and alter hemoglobin into non-oxygen-carrying cyanmethemoglobin. To neutralize this threat, a sulfur atom from thiosulphate is transferred to the cyanide ion, catalyzed by the enzyme rhodanese, resulting in an inactive compound called thiocyanate. The production of...
