Inhibition of carbonic anhydrase (CA, EC 4.2.1.1) has pharmacologic applications in the treatment of glaucoma, a disease affecting a large number of people and characterized by an elevated intraocular pressure (IOP).

They usually coordinate the catalytic Zn(II) ion in the active site (e.g., deprotonated primary and secondary sulfonamides and their bioisosteres, … Carbonic anhydrase inhibitors. The "receptor" for the clinically most important diuretics, i.e. Mechanism of the anticonvulsant action of acetazoleamide, a carbonic anhydrase inhibitor. Such a system would help maintain intracellular pH for the enzymes involved in ion transport.Some authorities propose that CAIs influence aqueous humor formation by altering systemic acid–base or electrolyte balance. Inhibition of the enzyme carbonic anhydrase increases the concentration of hydrogen ions intracellularly and decreases the pH. Their mechanism of action consists in inhibition of CA isozymes present in ciliary processes of the eye (such as CA II, IV and XII), with the consequent reduction of bicarbonate and aqueous humour secretion, and of elevated … Both drugs are used alone or in combination with β-blockers or PG receptor agonists. Epub 2013 Apr 30.de Leval X, Ilies M, Casini A, Dogné JM, Scozzafava A, Masini E, Mincione F, Starnotti M, Supuran CT.J Med Chem. Studies are underway to better understand mechanisms of the Rap1 isoforms.CAIs work by inhibition of luminal and cellular carbonic anhydrase, resulting in an alkaline diuresis with impaired reabsorption of NaAcetazolamide (Diamox) is readily absorbed. The drug is contraindicated in those with sulfonamide hypersensitivity.
They can be used with NaHCOLethargy, abnormal taste, paresthesia, gastrointestinal distress, malaise, and decreased libido are among the adverse effects seen with treatment. This issue of Expert Opinion on Therapeutic Patents is dedicated to carbonic anhydrase (CA, EC 4.2.1.1) inhibitors (CAIs), a highly dynamic research topic in the last years. They do not seem to be effective in treating acute, primary glaucoma.Carbonic anhydrase (CA) inhibitors block CA on the luminal membrane and inside proximal tubule cells (As diuretics, these agents have limited utility because of a rapid depletion of body bicarbonate stores and metabolic acidosis. For the reduction of intraocular pressure (IOP), acetazolamide inactivates carbonic anhydrase and interferes with the sodium pump, which decreases aqueous humor formation and thus lowers IOP. 2014 Nov 13;57(21):9152-67. doi: 10.1021/jm501314c. 2004 May 20;47(11):2796-804. doi: 10.1021/jm031116j.Curr Pharm Des. Macri and CevarioAs stated previously, we lack a complete understanding of the mechanism of action of CAIs.
Carbonic anhydrases (CAs, EC 4.2.1.1) are widespread metalloenzymes all over the phylogenetic tree, with at least 4 distinct gene families encoding for them.
Rap1B, on the other hand, appeared important in dynamic reformation of the barrier integrity following pathologic stress.
