N2 - Mounting evidence suggests that mitochondrial dysfunction plays a causal role in the etiology and progression of Alzheimers disease (AD). We recently showed that the carbonic anhydrase inhibitor (CAI) methazolamide (MTZ) prevents amyloid β (Aβ)-mediated onset of apoptosis in the mouse brain. In this study, we used MTZ and, for the first time, the analog CAI acetazolamide (ATZ) in neuronal and cerebral vascular cells challenged with Aβ, to clarify their protective effects and mitochondrial molecular mechanism of action. The CAIs selectively inhibited mitochondrial dysfunction pathways induced by Aβ, without affecting metabolic function. ATZ was effective at ...

The inhibition of a newly cloned human carbonic anhydrase (CA, EC 4.2.1.1), isozyme VII (hCA VII), has been investigated with a series of aromatic and heterocyclic sulfonamides, including some of the clinically used derivatives (acetazolamide, methazolamide, ethoxzolamide, dichlorophenamide, dorzolamide, brinzolamide and benzolamide), as well as the sulfamate antiepileptic drug topiramate. Inhibition data for the the other physiologically relevant cytosolic isoforms hCA I, hCA II and mCA XIII are also provided for comparison. hCA VII shows a high catalytic activity for the CO(2) hydration reaction, with a k(cat) of 9.5 x 10(5)s(-1) and k(cat)/K(m) of 8.3 x 10(7)M(-1)s(-1) at pH7.5 and 20 degrees C. A very interesting inhibition profile against hCA VII with this series of 32 sulfonamides/sulfamates was observed. hCA VII shows high affinity for all the investigated compounds, with inhibition constants in the range of 0.45-210 nM. Topiramate, ethoxzolamide and benzolamide showed subnanomolar hCA ...

Acetazolamide is a potent carbonic anhydrase inhibitor, effective in the control of fluid secretion, in the treatment of certain convulsive disorders and in the promotion of diuresis in instances of abnormal fluid retention. Acetazolamide is not a mercurial diuretic. Rather, it is a nonbacteriostatic sulfonamide possessing a chemical structure and pharmacological activity distinctly different from the bacteriostatic sulfonamides ...
This study focused on the synthesis and characterization of hydrazide ligands and their respective Pd(II) complexes and used high throughput screening to determine their α-glucosidase and carbonic anhydrase II enzyme inhibition activities. The physical, analytical (elemental analyses for C, H, N and Pd) and spectral (FT-IR, 1H NMR, 13C NMR, EI-mass) techniques utilized during characterization revealed the formation of square planar, neutral and 1:2 Pd(II)-hydrazide complexes with the general formula [PdL2Cl2]. In these Pd(II) complexes, the hydrazide ligands are monodentate; the terminal nitrogen is the donor atom. The uncoordinated hydrazide ligands were inactive against both α-glucosidase and carbonic anhydrase II enzymes; however, the respective Pd(II)-hydrazide complexes were approximately 300 times more potent α-glucosidase inhibitors than the standard compound, 1-deoxynojirimycin (DNJ). Some of the Pd(II) complexes also demonstrated potential carbonic anhydrase (CA) inhibition ...

Although acetazolamide is rarely used in heart failure, carbonic anhydrase inhibitors are quite valuable in patients with edema and metabolic alkalosis. The high bicarbonate levels in these patients make them particularly susceptible to the action of carbonic anhydrase inhibitors. Digoxin is useful in chronic systolic failure but is not first-line therapy. Dobutamine is appropriate only when diuresis has already been accomplished in severe acute failure. Hydrochlorothiazide and spironolactone are not adequate for first-line therapy of edema in failure. The answer is A. ...

Brinzolamide is a highly specific, non-competitive, reversible carbonic anhydrase inhibitor. 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. In humans, carbonic anhydrase exists as a number of isoenzymes, the most active being carbonic anhydrase II (CA-II). Inhibition of carbonic anhydrase in the ciliary processes of the eye decreases aqueous humor secretion, presumably by slowing the formation of bicarbonate ions with subsequent reduction in sodium and fluid transport. The result is a reduction in intraocular pressure. Brinzolamide is indicated in the treatment of elevated intraocular pressure in patients with ocular hypertension or open-angle glaucoma.
Trithiocarbonate (CS32-) inhibits with low micromolar affinities several mammalian carbonic anhydrases, CAs, EC 4.2.1.1 [Innocenti et al., Bioorg. Med. Chem. Lett. 2009, 19, 1855]. Here we report the X-ray crystal structure of the hCA II-trithiocarbonate adduct. Trithiocarbonate is monodentately bound to the Zn(II) ion and makes several hydrogen bonds with Thr199 and two water molecules from the enzyme active site. Its binding is different from that of ureate, another small inhibitor isosteric with trithiocarbonate but somehow mimicks the binding of the SO(2)NH moiety present in the sulfonamide inhibitors and is similar to that of bicarbonate. Compounds incorporating this new zinc-binding group, CS2-, may thus lead to new classes of potent inhibitors. Carbonic anhydrase inhibitors.

A tentative diagnosis of BDUMP was made. In an attempt to treat the serous detachments, ocular treatment was first initiated. Intravitreal 1.25 mg bevacizumab (Avastin, Genentech/Hoffmann-La Roche) was administered OS, and treatment with topical and systemic carbonic anhydrase inhibitors was prescribed: acetazolamide (Diamox) 250 mg once a day and dorzolamide hydrochloride ophthalmic solution 20 mg/mL (Trusopt) two times a day. However, no benefit was noted in terms of visual acuity or fundus lesions, until plasmapheresis was initiated 9 days after the tentative diagnosis. A total of seven sessions of plasma exchange were carried out during the following several weeks. In the meantime, investigations continued in search of a primary neoplasm. Positron emission tomography (PET) imaging showed enhanced activity in subclavicular, axillary and mediastinal lymph nodes. The mediastinal lymph nodes were biopsied and histopathological analysis demonstrated malignancy compatible with metastatic ...

ANS: C. In the distal tubule, sodium is typically exchanged for potassium and hydrogen. Blocking this exchange is what makes these agents potassium-sparing diuretics. Thiazide diuretics block NaCl reabsorption at the distal tubule. Loop diuretics are often called "high-ceiling" diuretics because they can cause 20% of the filtered load of NaCl and water to be excreted in the urine. They inhibit the reabsorption of NaCl at the thick ascending limb of the loop of Henle, where about 20% of filtered NaCl is usually reabsorbed. Carbonic anhydrase inhibitors (CAIs) prevent the normal breakdown of carbonic acid and decrease bicarbonate reabsorption. CAIs also inhibit NaCl reabsorption at the proximal tubule. The decreased osmotic gradient for water reabsorption results in increased delivery of NaHCO3, NaCl, and water from the proximal tubule. Osmotic diuretics are freely filtered at the glomerulus but are not reabsorbed. These agents remain in the tubule lumen and impair the ability of the proximal ...
Because of diurnal variations of intraocular pressure in individual patients, satisfactory response to twice a day therapy is best determined by measuring intraocular pressure at different times during the day. Therapy should be individualised. If the intraocular pressure of the patient is not adequately controlled on this regimen, concomitant therapy with pilocarpine, other miotics, epinephrine or systemically administered carbonic anhydrase inhibitors can be instituted. When a patient is transferred from several concomitantly administered anti-glaucoma agents individualization is required. Adjustment should involve one agent at a time made at intervals of not less than one week. A recommended approach is to continue the agents being used and add one drop of BETOPTIC in the affected eye(s) twice a day. On the following day, discontinue one of the other anti-glaucoma agents. The remaining anti-glaucoma agents may be decreased or discontinued according to the patients response to treatment ...

MK-417, a potent carbonic anhydrase inhibitor capable of reducing intraocular pressure after topical application, is currently under investigation for the treatment of glaucoma. The purposes of this study were to characterize dose-dependent pharmacokinetics of MK-417 and to determine the accumulating effect of the drug during chronic topical administration in rabbits. Because the drug resided primarily in the erythrocytes, kinetic analyses were performed on whole blood concentration data. Following i.v. administration, both total blood clearance and apparent volume of distribution for MK-417 increased disproportionately between the low and high dose, while the half-life of the drug appeared to be independent of dose. Total blood clearance and apparent volume of distribution increased from 0.993 +/- 0.224 ml/hr/kg (mean +/- SD) and 88.6 +/- 9.4 ml/kg at a dose of 0.05 mg/kg to 2.73 +/- 0.17 ml/hr/kg and 272 +/- 5.5 ml/kg at a dose of 1 mg/kg. The dose-dependent kinetics of MK-417 are probably due ...

Methazolamide is a potent inhibitor of carbonic anhydrase.. Methazolamide is well absorbed from the gastrointestinal tract. Peak plasma concentrations are observed 1 to 2 hours after dosing. In a multiple-dose, pharmacokinetic study, administration of methazolamide 25 mg b.i.d., 50 mg b.i.d. and 100 mg b.i.d. demonstrated a linear relationship between plasma methazolamide levels and methazolamide dose. Peak plasma concentrations (Cmax) for the 25 mg, 50 mg and 100 mg b.i.d. regimens were 2.5 mcg/mL, 5.1 mcg/mL and 10.7 mcg/mL, respectively. The area under the plasma concentration-time curves (AUC) were 1130 mcg. min/mL, 2571 mcg. min/mL and 5418 mcg. min/mL for the 25 mg, 50 mg and 100 mg dosage regimens, respectively.. Methazolamide is distributed throughout the body including the plasma, cerebrospinal fluid, aqueous humor of the eye, red blood cells, bile and extracellular fluid. The mean apparent volume of distribution (Varea/F) ranges from 17 to 23 L. Approximately 55% is bound to plasma ...

We sought to determine whether carbonic anhydrase inhibition with acetazolamide would prevent CO2-mediated inhibition of LPS-stimulated TNF release. Murine peritoneal macrophages were treated with acetazolamide for 1 h under control atmosphere (95% air/5% CO2) and then switched to incubator modules containing: 1) 80% CO2/20% O2, 2) 80% He/20% O2, or 3) 100% air. Before transfer to experimental atmospheric conditions the ...
Though carcinoids are slow growing tumors, which can be treated by surgery, the survival in metastatic carcinoids is very low because the treatment strategies for other cancers are not effective for dealing with advanced stage carcinoids [36]. Therefore, the investigations concerning the discovery of new strategies for treating pulmonary carcinoids need to be focused on therapies that can inhibit the growth and invasiveness of advanced stage disease. Carcinoid tumors are proving moderately responsive to newer therapies targeting tumor vasculature and survival pathways [1, 2]. The mammalian target of rapamycin (mTOR) inhibitor, everolimus, has shown promising initial results alone or combined with other agents [37-39]. Bronchial AC, which is characterized by high mTOR expression, has been reported to be responders to mTOR inhibition, indicating that therapies targeting the critical survival pathways are potential candidates to treat bronchial carcinoids [40]. The evidence seems to indicate that ...

Prostaglandin derivatives, parasympathomimetics, β blockers, and carbonic anhydrase inhibitors are the major drug classes that are used in the management of glaucoma.4,5 Prostaglandin derivatives, such as latanoprost and bimatoprost, increase the aqueous humor (AH) outflow through the uveoscleral pathway. Several mechanisms have been proposed to explain how prostaglandin derivatives reduce the IOP. Relaxation of the ciliary muscles, which causes the connective tissue-filled spaces in the trabecular meshwork to widen, is thought to be a factor that is involved in the initial drop in IOP.6 Prostaglandin analogs also induce the release of matrix metalloproteinase enzymes and cause the dissolution of types I and III collagen within the connective tissue-filled spaces.7 This process also leads to an increase in the AH outflow through the trabecular meshwork. Pilocarpine is a direct-acting cholinergic parasympathomimetic agent. It directly stimulates the muscarinic receptors and smooth muscles of the ...

ISSN 0718-5839. http://dx.doi.org/10.4067/S0718-58392012000100022.. Carbonic anhydrase (CA) (EC: 2.4.1.1) catalyzes the rapid conversion of carbon dioxide plus water into a proton and the bicarbonate ion (HCO3-) that can be found in prokaryotes and higher organisms; it is represented by four different families. Carbonic anhydrase is a metalloenzyme that requires Zn as a cofactor and is involved in diverse biological processes including pH regulation, CO2 transfer, ionic exchange, respiration, CO2 photosynthetic fixation, and stomatal closure. Therefore, the review includes relevant aspects about CA morphology, oligomerization, and structural differences in the active site. On the other hand, we consider the general characteristics of Zn, its geometry, reactions, and physiology. We then consider the CA catalysis mechanism that is carried out ...
