A class of compounds that reduces the secretion of H+ ions by the proximal kidney tubule through inhibition of CARBONIC ANHYDRASES.
One of the CARBONIC ANHYDRASE INHIBITORS that is sometimes effective against absence seizures. It is sometimes useful also as an adjunct in the treatment of tonic-clonic, myoclonic, and atonic seizures, particularly in women whose seizures occur or are exacerbated at specific times in the menstrual cycle. However, its usefulness is transient often because of rapid development of tolerance. Its antiepileptic effect may be due to its inhibitory effect on brain carbonic anhydrase, which leads to an increased transneuronal chloride gradient, increased chloride current, and increased inhibition.

Does gill boundary layer carbonic anhydrase contribute to carbon dioxide excretion: a comparison between dogfish (Squalus acanthias) and rainbow trout (Oncorhynchus mykiss). (1/420)

In vivo experiments were conducted on spiny dogfish (Squalus acanthias) and rainbow trout (Oncorhynchus mykiss) in sea water to determine the potential role of externally oriented or gill boundary layer carbonic anhydrase in carbon dioxide excretion. This was accomplished by assessing pH changes in expired water using a stopped-flow apparatus. In dogfish, expired water was in acid-base disequilibrium as indicated by a pronounced acidification (delta pH=-0.11+/-0.01; N=22; mean +/- s.e.m.) during the period of stopped flow; inspired water, however, was in acid-base equilibrium (delta pH=-0.002+/-0.01; N=22). The acid-base disequilibrium in expired water was abolished (delta pH=-0.005+/-0.01; N=6) by the addition of bovine carbonic anhydrase (5 mg l-1) to the external medium. Addition of the carbonic anhydrase inhibitor acetazolamide (1 mmol l-1) to the water significantly reduced the magnitude of the pH disequilibrium (from -0.133+/-0.03 to -0.063+/-0.02; N=4). However, after correcting for the increased buffering capacity of the water caused by acetazolamide, the acid-base disequilibrium during stopped flow was unaffected by this treatment (control delta [H+]=99.8+/-22.8 micromol l-1; acetazolamide delta [H+]=81.3+/-21.5 micromol l-1). In rainbow trout, expired water displayed an acid-base disequilibrium (delta pH=0.09+/-0.01; N=6) that also was abolished by the application of external carbonic anhydrase (delta pH=0.02+/-0.01). The origin of the expired water acid-base disequilibrium was investigated further in dogfish. Intravascular injection of acetazolamide (40 mg kg-1) to inhibit internal carbonic anhydrase activity non-specifically and thus CO2 excretion significantly diminished the extent of the expired water disequilibrium pH after 30 min (from -0.123+/-0.01 to -0.065+/-0.01; N=6). Selective inhibition of extracellular carbonic anhydrase activity using a low intravascular dose (1.3 mg kg-1) of the inhibitor benzolamide caused a significant reduction in the acid-base disequilibrium after 5 min (from -0.11+/-0.01 to -0.07+/-0. 01; N=14). These results demonstrate that the expired water acid-base disequilibrium originates, at least in part, from excretory CO2 and that extracellular carbonic anhydrase in dogfish may have a significant role in carbon dioxide excretion. However, externally oriented carbonic anhydrase (if present in dogfish) plays no role in catalysing the hydration of the excretory CO2 in water flowing over the gills and thus is unlikely to facilitate CO2 excretion.  (+info)

Synaptic activation of GABAA receptors induces neuronal uptake of Ca2+ in adult rat hippocampal slices. (2/420)

Synaptically evoked transmembrane movements of Ca2+ in the adult CNS have almost exclusively been attributed to activation of glutamate receptor channels and the consequent triggering of voltage-gated calcium channels (VGCCs). Using microelectrodes for measuring free extracellular Ca2+ ([Ca2+]o) and extracellular space (ECS) volume, we show here for the first time that synaptic stimulation of gamma-aminobutyric acid-A (GABAA) receptors can result in a decrease in [Ca2+]o in adult rat hippocampal slices. High-frequency stimulation (100-200 Hz, 0.4-0.5 s) applied in stratum radiatum close (+info)

Modulation of chloride, potassium and bicarbonate transport by muscarinic receptors in a human adenocarcinoma cell line. (3/420)

1. Short-circuit current (I(SC)) responses to carbachol (CCh) were investigated in Colony 1 epithelia, a subpopulation of the HCA-7 adenocarcinoma cell line. In Krebs-Henseleit (KH) buffer, CCh responses consisted of three I(SC) components: an unusual rapid decrease (the 10 s spike) followed by an upward spike at 30 s and a slower transient increase (the 2 min peak). This response was not potentiated by forskolin; rather, CCh inhibited cyclic AMP-stimulated I(SC). 2. In HCO3- free buffer, the decrease in forskolin-elevated I(SC) after CCh was reduced, although the interactions between CCh and forskolin remained at best additive rather than synergistic. When Cl- anions were replaced by gluconate, both Ca2+- and cyclic AMP-mediated electrogenic responses were significantly inhibited. 3. Basolateral Ba2+ (1-10 mM) and 293B (10 microM) selectively inhibited forskolin stimulation of I(SC), without altering the effects of CCh. Under Ba2+- or 293B-treated conditions, CCh responses were potentiated by pretreatment with forskolin. 4. Basolateral charybdotoxin (50 nM) significantly increased the size of the 10 s spike of CCh responses in both KH and HCO3- free medium, without affecting the 2 min peak. The enhanced 10 s spike was inhibited by prior addition of 5 mM apical Ba2+. Charybdotoxin did not affect forskolin responses. 5. In epithelial layers prestimulated with forskolin, the muscarinic antagonists atropine and 4-diphenylacetoxy-N-methylpiperidine methiodide (4-DAMP, both at 100 nM) abolished subsequent 10 microM CCh responses. Following addition of p-fluoro hexahydro-sila-difenidol (pF-HHSiD, 10 microM) or pirenzepine (1 microM), qualitative changes in the CCh response time-profile also indicated a rightward shift of the agonist concentration-response curve; however, 1 microM gallamine had no effect. These results suggest that a single M3-like receptor subtype mediates the secretory response to CCh. 6. It is concluded that CCh and forskolin activate discrete populations of basolateral K+ channels gated by either Ca2+ or cyclic AMP, but that the Cl- permeability of the apical membrane may limit their combined effects on electrogenic Cl- secretion. In addition, CCh activates a Ba2+-sensitive apical K+ conductance leading to electrogenic K+ transport. Both agents may also modulate HCO3- secretion through a mechanism at least partially dependent on carbonic anhydrase.  (+info)

Effects of maternal acetazolamide treatment on body weights and incisor development of the fetal rat. (4/420)

The incisor development of fetal rats on gestation day 19 was well correlated with their fetal weights. The number of odontoblasts in the mandibular incisors, an index of incisor development, increased more than that of the maxillary incisors with increase in fetal body weights. Maternal acetazolamide treatments were observed to suppress the mean fetal weight and to retard incisor development. A smaller incisor size, a thinner predentin layer, and fewer odontoblasts were characteristic of the acetazolamide group. There was also a good correlation between the fetal weights and the number of odontoblasts in the acetazolamide group. From these results, we postulated that the retarded incisor development of the fetal rats caused by the maternal acetazolamide treatment was related to their suppressed fetal weights. However, the regression coefficient of the fetal weights and the number of odontoblasts in the acetazolamide group was smaller than that of the vehicle control group. It may indicate that retarded incisor development in response to maternal acetazolamide treatment is to some extent independent of suppressed fetal weight.  (+info)

Endogenous pH shifts facilitate spreading depression by effect on NMDA receptors. (5/420)

Rapid extracellular alkalinizations accompany normal neuronal activity and have been implicated in the modulation of N-methyl-D-aspartate (NMDA) receptors. Particularly large alkaline transients also occur at the onset of spreading depression (SD). To test whether these endogenous pH shifts can modulate SD, the alkaline shift was amplified using benzolamide, a poorly permeant inhibitor of interstitial carbonic anhydrase. SD was evoked by microinjection of 1.2 M KCl into the CA1 stratum radiatum of rat hippocampal slices and recorded by a proximal double-barreled pH microelectrode and a distal potential electrode. In Ringer solution of pH 7.1 containing picrotoxin (but not at a bath pH of 7.4), addition of 10 microM benzolamide increased the SD alkaline shift from 0.20 +/- 0.07 to 0.38 +/- 0.17 unit pH (means +/- SE). This was correlated with a significant shortening of the latency and an increase in the conduction velocity by 26 +/- 16%. In the presence of the NMDA receptor antagonist DL-2-amino-5-phosphonovaleric acid (APV), benzolamide still amplified the alkaline transient, however, its effect on the SD latency and propagation velocity was abolished. The intrinsic modulation of SD by its alkaline transient may play an important role under focal ischemic conditions by removing the proton block of NMDA receptors where interstitial acidosis would otherwise limit NMDA receptor activity.  (+info)

Inhibition of carbonic anhydrase accounts for the direct vascular effects of hydrochlorothiazide. (6/420)

Hydrochlorothiazide has been shown to exert direct vasodilator effects by activation of calcium-activated potassium (KCa) channels in human and guinea pig isolated resistance arteries. Since hydrochlorothiazide binds to and inhibits the enzyme carbonic anhydrase and because KCa channel activation is pH sensitive, we investigated the role of intracellular and extracellular carbonic anhydrase in the vascular effects of thiazide diuretics. Small arteries were isolated from guinea pig mesentery and studied by use of a microvascular myograph technique. In some experiments, tone and intracellular pH (pHi) were measured simultaneously with 2', 7'-bis(2-carboxyethyl)-5(6)'-carboxyfluorescein (BCECF-AM). Bendroflumethiazide, a thiazide diuretic with minimal inhibitory effects on carbonic anhydrase, had little effect on noradrenaline-induced tone (16+/-8% relaxation) compared with hydrochlorothiazide (74+/-12% relaxation). In contrast to hydrochlorothiazide, the action of bendroflumethiazide was unaffected by 100 nmol/L charybdotoxin, a selective blocker of KCa channels. All inhibitors of carbonic anhydrase relaxed noradrenaline-induced tone in a concentration-dependent manner, and this effect was blocked by charybdotoxin. Hydrochlorothiazide and the inhibitors of carbonic anhydrase failed to relax tone induced by a depolarizing potassium solution. Acetazolamide and hydrochlorothiazide increased pHi by 0.27+/-0.07 and 0.21+/-0.04, respectively, whereas bendroflumethiazide had a much smaller effect: 0.06+/-0.03. The rise in pHi induced by any agent was not inhibited by charybdotoxin. The vasorelaxant effect of hydrochlorothiazide is shared by other inhibitors of carbonic anhydrase. Inhibitors of carbonic anhydrase, but not bendroflumethiazide, cause intracellular alkalinization, which is associated with KCa channel opening. These data suggest that the vasodilator effect of thiazide diuretics results primarily from inhibition of vascular smooth muscle cell carbonic anhydrase, which results in a rise in pHI, leading to KCa channel activation and vasorelaxation.  (+info)

Topical therapies for glaucoma: what family physicians need to know. (7/420)

Medication classes historically used in the management of glaucoma include beta blockers, miotics, sympathomimetics and carbonic anhydrase inhibitors. Because topically applied medications are more site specific, they are preferred in the treatment of glaucoma. Compared with oral medications, topical agents are associated with a decreased incidence of systemic side effects. With topical administration, conjunctival and localized skin allergic reactions are relatively common, whereas severe reactions, including death, are rare. Recently introduced topical agents for glaucoma therapy include dorzolamide and brinzolamide, the first topical carbonic anhydrase inhibitors; brimonidine and apraclonidine, more ocular-specific alpha agonists; and latanoprost, a prostaglandin analog, which is a new class of glaucoma medication. Latanoprost has the unique side effect of increasing iris pigmentation. Like their predecessors, the newer agents lower intraocular pressure by a statistically significant degree. Preservation of visual field, the more substantial patient-oriented end point, continues to be studied.  (+info)

VCO2 and VE kinetics during moderate- and heavy-intensity exercise after acetazolamide administration. (8/420)

The effect of carbonic anhydrase inhibition with acetazolamide (Acz) on CO2 output (VCO2) and ventilation (VE) kinetics was examined during moderate- and heavy-intensity exercise. Seven men [24 +/- 1 (SE) yr] performed cycling exercise during control (Con) and Acz (10 mg/kg body wt iv) sessions. Each subject performed step transitions (6 min) in work rate from 0 to 100 W [below ventilatory threshold (VET)]. VE and gas exchange were measured breath by breath. The time constant (tau) was determined for exercise VET by using a three-component model (fit from the start of exercise). VCO2 kinetics were slower in Acz (VET, MRT = 75 +/- 10 s) than Con (VET, MRT = 54 +/- 7 s). During VET kinetics were faster in Acz (MRT = 85 +/- 17 s) than Con (MRT = 106 +/- 16 s). Carbonic anhydrase inhibition slowed VCO2 kinetics during both moderate- and heavy-intensity exercise, demonstrating impaired CO2 elimination in the nonsteady state of exercise.

Background Glaucoma is a leading cause of blindness worldwide. Chronic primary open-angle glaucoma is the most common form among Caucasian patients. The key feature of glaucoma is damage to the optic nerve head, which is not necessarily related to an increase in intraocular pressure (IOP). The actual therapeutic armamentarium for glaucoma includes miotics, beta-blockers, alpha-adrenergic agonists, oral and topical carbonic anhydrase inhibitors, and prostaglandin analogues, the latter being the latest addition to the armamentarium and the most potent topical IOP lowering drugs. Besides IOP, ocular blood flow alterations have been incriminated in glaucoma. Hence, it is of relevance to assess the effect of anti-glaucomatous drugs on ocular blood flow.. Rationale of the study Vasoactivity of topical drugs may be of prognostic relevance in glaucoma. There is very little information for a major class, the prostaglandin analogues with regard to this aspect. The vascular activity of two prostaglandin ...

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 ...

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.

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 ...

2h15: Carbonic anhydrase inhibitors: clash with Ala65 as a means for designing inhibitors with low affinity for the ubiquitous isozyme II, exemplified by the crystal structure of the topiramate sulfamide analogue.
In eukaryotes, some transcriptional repressors compete with activators for the same DNA sequence - think of it as similar to how an enzyme inhibitor works e.g. in a similar way to how carbonic anhydrase inhibitors used as diuretics (to get rid of excess fluid from the body by increasing urine volume) compete with H2CO3 (the normal substrate) for active sites of the enzyme. Here the repressor has affinity for a particular set of nucleotides for which the activator also has affinity, yeah ...

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.

N2 - We previously showed that incubation in carbon dioxide (CO2), but not air or helium (He), markedly decreased macrophage intracellular pH (pHi) and resulted in reversible inhibition of lipopolysaccharide- (LPS) stimulated tumor necrosis factor (TNF) and interleukin-1 release. 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 ...

One of the four discrete isoenzymes of carbonic anhydrase hitherto characterized, CA III, has the lowest turnover rate and the greatest resistance to inhibition by sulphonamides. Streptozotocin-induced diabetes mellitus resulted in a reduction in acetazolamide-resistant activity of carbonic anhydrase in the liver, but not in tonic skeletal muscle, of adult male rats. The hepatic activity declined with apparent first-order kinetics [calculated rate constant (k) 0.089 day-1] to a minimum of approx. 6% of control values; the reduction in activity was moderated by administration of insulin. ...

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 ...

In this study, bovine articular and human chondrocytes from the C-20/A4 cell line were tested for the functional activity and molecular presence of the enzyme carbonic anhydrase. This enzyme is classically considered to be important in the maintenance of high cellular buffering capacity by catalysing the slow attainment of equilibrium between CO(2) and HCO(3)(-). The first functional assay measured the rate of pH equilibration after administration of a fixed dose of CO(2) solution to cell lysates. Compared to positive controls (human erythrocytes, murine M1 cells and purified carbonic anhydrase), chondrocyte lysates attained equilibrium at a significantly slower rate, similar to the rate obtained with a negative control (Xenopus oocytes). A second functional assay studied CO(2) hydration kinetics in intact C-20/A4 cells, using a pH-sensitive fluorescent dye, as the CO(2) content of the extracellular solution was changed. It was shown that C-20/A4 cells accelerate hydration only to a small degree.
The enzyme carbonic anhydrase has been well characterized in mammalian systems, but the structural properties of the plant isozymes remain elusive.

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 ...

The high metabolic rate required for tumor growth often leads to hypoxia in poorly-perfused regions. Hypoxia activates a complex gene expression program, mediated by hypoxia inducible factor 1 (HIF1alpha). One of the consequences of HIF1alpha activation is up-regulation of glycolysis and hence the production of lactic acid. In addition to the lactic acid-output, intracellular titration of acid with bicarbonate and the engagement of the pentose phosphate shunt release CO(2) from cells. Expression of the enzyme carbonic anhydrase 9 on the tumor cell surface catalyses the extracellular trapping of acid by hydrating cell-generated CO(2) into [see text] and H(+). These mechanisms contribute towards an acidic extracellular milieu favoring tumor growth, invasion and development. The lactic acid released by tumor cells is further metabolized by the tumor stroma. Low extracellular pH may adversely affect the intracellular milieu, possibly triggering apoptosis. Therefore, primary and secondary active transporters
We report the cloning, purification and characterization of the full domain of carbonic anhydrase (CA, EC 4.2.1.1) from Plasmodium falciparum, which incorporates 358 amino acid residues (from 181 to 538, in the sequence of this 600 amino acid long protein), called PfCAdom. The enzyme, which belongs to the η-CA class showed the following kinetic parameters: kcat of 3.8×10(5)s(-1) and kcat/Km of 7.2×10(7)M(-1)×s(-1), being 13.3 times more effective as a catalyst compared to the truncated form PfCA. PfCAdom is more effective than the human (h) isoform hCA I, being around 50% less effective compared to hCA II, one of the most catalytically efficient enzymes known so far. Intriguingly, the sulfonamides CA inhibitors generally showed much weaker inhibitory activity against PfCAdom compared to PfCA, prompting us to hypothesize that the 69 amino acid residues insertion present in the active site of this η-CA is crucial for the active site architecture. The best sulfonamide inhibitors for PfCAdom ...

Carbonic anhydrase IX (CAIX) is a hypoxia-induced, membrane-tethered enzyme that is highly expressed in many cancers. It catalyses the hydration of CO 2 to HCO3- and H+, and the reverse dehydration reaction. Recent studies have shown an important role for CAIX in pH regulation and it has been speculated that CAIX may play a role in supporting cancer progression towards more aggressive forms of the disease. Clinical correlative studies in many tumours have shown that high expression is related to poor outcome. In the present study, we have selected antigen-binding antibody fragments (Fab) against human CAIX by phage-display, and tested these for inhibitory potency on CAIX catalytic activity. Inhibition was assessed from the kinetics of the CAIX-catalysed reaction, using assays performed on intact cells over-expressing CAIX, and their CAIX-containing membrane fragments. Inhibition was also assessed in multi-cellular tissue-models (spheroids) from the kinetics of CO2 venting. We have identified a Fab

Carbonic anhydrase (CA; EC 4.2.1.1) is a zinc containing enzyme which catalyzes a reversible reaction to form bicarbonate from carbon dioxide and water [1, 2]. By facilitating the interconversion between CO2 and bicarbonate in vivo, CA activity was proposed to be required to ensure adequate level of CO2or HCO3- as the substrates for other enzymes [3]. Therefore, CAs have been found to play an essential role in a series of fundamental biological processes such as photosynthesis, respiration, pH homeostasis and ion transport [4]. Based on the origins and structural features, CAs are divided into six classes, termed α, β, γ, δ, ε and ζ, respectively [5]. The α-CAs were found in mammals, algae and prokaryotes to facilitate the exchange of CO2 in the respiratory cycle. The β-CAs were characterized in higher plants, algae and prokaryotes, and those in higher plants have been reported to play a critical role during photosynthesis [6]. The γ-class was first identified in the thermophilic ...
