A group of enzymes called carbonic anhydrases are responsible for the secretion of aqueous humour, but sometimes they get carried away and produce too much fluid, causing a rise in intraocular pressure. | Puccetti L, Fasolis G, Vullo D, Chohan ZH, Scozzafava A, Supuran CT.

Anion Inhibition Profile of the β-Carbonic Anhydrase from the Opportunist Pathogenic Fungus, The first activation study of the β-carbonic anhydrases from the pathogenic bacteria. This leads to a direct increase in urinary bicarbonate excretion and secondarily to mild increases in sodium and potassium excretion. To tackle problem carbonic anhydrase inhibitors (CAIs are used to suppress the activity of carbonic anhydrase enzymes.

To date, catechols have been only poorly investigated as carbonic anhydrase (CA) inhibitors. Claudiu T. Supuran. Several nanomolar (K(i)'s in the range of 6-54 nM) CA IX inhibitors have also been detected. 2005 May 2;15(9):2359-64. doi: 10.1016/j.bmcl.2005.02.087. Examples of carbonic inhibitor medications currently available are acetazolamide, methazolamide, dorzolamide, brinzolamide, diclofenamide, ethoxzolamide, and zonisamide. 2019 Jul 18;9(7):147. doi: 10.3390/metabo9070147. | Here we report the first structural information on the CA inhibition mechanism of these molecules, showing that they adopt a peculiar binding mode to the enzyme active site which involves the zinc-bound water molecule and the “deep water”. Inorganic anions, such as I −, CN −, SH −, CNO −, SCN −, and Br −, and sulfonamides are inhibitors of the enzyme carbonic anhydrase (Maren 1967). Pharmacology: Carbonic anhydrase (CA) is an enzyme found in many tissues of the body including the eye.It catalyzes the reversible reaction involving the hydration of carbon dioxide and the dehydration of carbonic acid. 2003 Mar 24;13(6):1005-9. doi: 10.1016/s0960-894x(03)00091-x.

Carbonic anhydrase inhibitors: inhibition of the tumor-associated isozyme IX with aromatic and heterocyclic sulfonamides. This reduces the resorption of bicarbonate from the proximal tubule in the kidneys, which causes a direct increase in bicarbonate excretion and mild increases in sodium, and potassium excretion. The successful treatment of schisis cavities with carbonic anhydrase inhibitor has been previously reported.111 Genead et al.112 treated 29 eyes of 15 XLRS patients with topical dorzolamide for 441 months and noted some positive effects on visual acuity, cystoid macular lesions, and central foveal thickness.
