Carbonic Anhydrase

Carbonic anhydrase inhibitor 6 is a potent human carbonic anhydrase (hCA) inhibitor that inhibits hCA IX, hCA II, hCA XII, and hCA I. It is used in the study of diseases caused by abnormalities in carbonic anhydrase.

Carbonic Anhydrase Inhibitor 12 is a potent inhibitor of CA II, with additional inhibitory activity against CA I, exhibiting K_i values of 1.72 nM for CA II and 271 nM for CA I. Moreover, it demonstrates significant anticancer activity across various cancer cell lines [1].

Carbonic Anhydrase Inhibitor 15 (Compound 8), with an inhibitory constant (K_i) of 8.5 nM for hCA II, exhibits analgesic effects [1].

Compound 1e, also known as ALP/Carbonic anhydrase-IN-1, is a dual inhibitor targeting both carbonic anhydrase (CA) isozymes II, IX, and XII, as well as alkaline phosphatase (ALP). It exhibits inhibitory IC50 values of 0.44 µM for CA-II, 1.61 µM for CA-IX, 0.51 µM for CA-XII, and 0.107 µM for ALP [1].

Enpp/Carbonic anhydrase-IN-1 (compound 1e) is a potent inhibitor of Enpp and carbonic anhydrase, exhibiting IC50s of 1.36, 1.35, 3.00, 0.88, and 1.02 µM for NPP1, NPP2, NPP3, CA-II, and CA-IX respectively. Enpp/Carbonic anhydrase-IN-1 also demonstrates selective antiproliferative activity for cancer cells.

Sultiame is an inhibitor of carbonic anhydrase. Sultiame can be used in antiepileptic research.

EMD57033 is a cardiac troponin C (cTnC) activator, a dominant Ca2+ sensitizer, which functions by binding to cardiac/slow skeletal troponin C heterodimers to promote cardiac contraction.

(Iso)-Samixogrel shows activity against Carbonic anhydrase and Cyclooxygenase 2.

Halazone (Pantocid) is fine white powder with an odor of chlorine. It has been widely used to disinfect drinking water.

Methazolamide (CL 8490) is a carbonic anhydrase inhibitor that is used as a diuretic and in the treatment of glaucoma.

Trichlormethiazide (Naqua) is a short-acting, 3-dichloromethyl derivative of hydrochlorothiazide, belonging to the class of thiazide diuretics. Trichlormethiazide appears to block the active reabsorption of chloride and possibly sodium in the ascending loop of Henle, altering electrolyte transfer in the proximal tubule.

Brinzolamide (AL-4862) is a Carbonic Anhydrase Inhibitor. Its mechanism of action involves inhibiting the enzyme Carbonic Anhydrase.

Zonisamide (AD 810), a sulfonamide anticonvulsant, is approved for use as an adjunctive treatment in adults with partial-onset seizures. It may inhibit a carbonic anhydrase although this is not one of the main mechanisms of action. Zonisamide may act by blocking repetitive firing of voltage-gated sodium channels results in a reduction of T-type calcium channel currents, or by binding allosterically to GABA receptors. This latter action may lower the uptake of the inhibitory neurotransmitter GABA while increasing the uptake of the excitatory neurotransmitter glutamate.

Ellagic acid (Gallogen), a thickened tetracyclic natural product, is a potent CK2 inhibitor (IC50=40 nM; Ki=20 nM) with ATP-competitive properties. Ellagic acid is an antioxidant and also possesses antiproliferative activity.

Tioxolone is a metalloenzyme carbonic anhydrase I inhibitor.

Topiramate (RWJ 17021) is a unique antiseizure medication that is used in the treatment of partial and generalized seizures. Topiramate has been rarely associated with hepatic injury and largely when used in combination with other anticonvulsant medications.

Urea (Carbonyldiamide) is formed in the liver from ammonia produced by the deamination of amino acids. It is the principal end metabolite of protein catabolism and accounts for about one-half of the total urinary solids.

Benzthiazide (Lemazide) is used in the therapy of edema and hypertension. Like other thiazides, benzthiazide accelerates water loss from the body (diuretics). They inhibit Na+/Cl- reabsorption from the distal convoluted tubules in the kidneys. Thiazides also cause loss of potassium and an increase in serum uric acid. Thiazides are often used to treat hypertension, but their hypotensive effects are not necessarily due to their diuretic activity. Thiazides have been shown to prevent hypertension-related morbidity and mortality although the mechanism is not fully understood. Thiazides cause vasodilation by activating calcium-activated potassium channels (large conductance) in vascular smooth muscles and inhibiting various carbonic anhydrases in vascular tissue.

Acetazolamide (Diamox) is a Carbonic Anhydrase Inhibitor. The mechanism of action of acetazolamide is as a Carbonic Anhydrase Inhibitor. The chemical classification of acetazolamide is Sulfonamides.

Mafenide hydrochloride (4-Aminomethylbenzenesulfonamide hydrochloride) is a sulfonamide that inhibits the enzyme carbonic anhydrase and is used as topical anti-infective, especially in burn therapy.

Methocarbamol (AHR 85) is a centrally acting muscle relaxant whose mode of action has not been established. It is used as an adjunct in the symptomatic treatment of musculoskeletal conditions associated with painful muscle spasm.

Hydrochlorothiazide (HCTZ) is a Thiazide Diuretic. The physiologic effect of hydrochlorothiazide is by means of Increased Diuresis.

Dorzolamide hydrochloride (MK507 hydrochloride) is the hydrochloride salt form of dorzolamide, an inhibitor of carbonic anhydrase, a zinc-containing enzyme that catalyzes the rapid conversion of carbon dioxide and water into carbonic acid, protons and bicarbonate ions. Distributed throughout many cells and tissues, various carbonic anhydrases play important roles in mineral and metabolic homeostasis.

Orthanilamide (Orthanilamide) is a molecule containing the sulfonamide functional group attached to an aniline.
