چکیده انگلیسی
The membrane-associated mouse isozyme of carbonic anhydrase XV (mCA XV), has been investigated for its interaction with anion inhibitors. mCA XV is an isoforms possessing a very particular inhibition profile by anions, dissimilar to that of all other mammalian CAs investigated earlier. Many simple inorganic anions (thiocyanate, cyanide, azide, bicarbonate, hydrogen sulfide, bisulfite and sulfate) showed low micromolar inhibition constants against mCA XV (KIs of 8.2-10.1 μM), whereas they acted as much weaker (usually millimolar) inhibitors of other isoforms. Halides, nitrate, nitrite, carbonate, sulfamate, sulfamide and phenylboronic/arsonic acid were weaker inhibitors, with inhibition constants in the range of 27.6-288 μM. Our data may be useful for the design of more potent inhibitors of mCA XV (considering various zinc binding groups present in the anions investigated here, e.g., the sulfonate one) and for understanding some physiologic/pharmacologic consequences of mCA XV inhibition by anions such as bicarbonate or sulfate which show quite high affinity for it.
