Abstract
INTRODUCTION Carbonic anhydrases (CAs, EC 4.2.1.1) have been established drug targets for decades, with their inhibitors and activators possessing relevant pharmacological activity and applications in various fields. At least 11 sulfonamides/sulfamates are clinically used as diuretics, antiglaucoma, antiepileptic, or antiobesity agents and one derivative, SLC-0111, is in clinical trials as antitumor/antimetastatic agent. The activators were less investigated with no clinically used agent. AREAS COVERED Drug interactions between CA inhibitors/activators and various other agents are reviewed in publications from the period March 2020 - January 2024. EXPERT OPINION Drug interactions involving these agents revealed several interesting findings. Acetazolamide plus loop diuretics is highy effective in acute decompensated heart failure, whereas ocular diseases such as X-linked retinoschisis and macular edema were treated by acetazolamide plus bevacizumab or topical NSAIDs. Potent anti-infective effects of acetazolamide and other CAIs, alone or in combination with other agents were demonstrated for the management of Neisseria gonorrhoea, vancomycin resistant enterococci, Acanthamoeba castellanii, Trichinella spiralis, and Cryptococcus neoformans infections. Topiramate, in combination with phentermine is incresingly used for the management of obesity, whereas zonisamide plus levodopa is highly effective for Parkinson's disease. Acetazolamide, methazolamide, ethoxzolamide, and SLC-0111 showed synergistic antitumor/antimetastatic action in combination with many other antitumor drugs.

Abstract
Carbonic anhydrases (CAs) are ubiquitous enzymes that catalyze the reversible carbon dioxide hydration reaction. Among the eight different CA classes existing in nature, the α-class is the largest one being present in animals, bacteria, protozoa, fungi, and photosynthetic organisms. Although many studies have been reported on these enzymes, few functional, biochemical, and structural data are currently available on α-CAs isolated from photosynthetic organisms. Here, we give an overview of the most recent literature on the topic. In higher plants, these enzymes are engaged in both supplying CO2 at the Rubisco and determining proton concentration in PSII membranes, while in algae and cyanobacteria they are involved in carbon-concentrating mechanism (CCM), photosynthetic reactions and in detecting or signaling changes in the CO2 level in the environment. Crystal structures are only available for three algal α-CAs, thus not allowing to associate specific structural features to cellular localizations or physiological roles. Therefore, further studies on α-CAs from photosynthetic organisms are strongly needed to provide insights into their structure–function relationship.

Zeta-carbonic anhydrases show CS 2 hydrolase activity: A new metabolic carbon acquisition pathway in diatoms? Comput Struct Biotechnol J 2021; 19:3427-3436. [PMID: 34194668 PMCID: PMC8217695 DOI: 10.1016/j.csbj.2021.05.057] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2021] [Revised: 05/27/2021] [Accepted: 05/30/2021] [Indexed: 12/26/2022] Open
Abstract
CDCA1 is a carbonic anhydrase that can utilize Zn(II) or Cd(II) as catalytic metal. CDCA1 has been the first enzyme to show an efficient utilization of Cd(II) ions in Nature. By using a multidisciplinary approach, we discovered that CS2 is a substrate for this enzyme. CDCA1 is the unique enzyme, known so far, able to use both CS2 and CO2 as substrates.
CDCA1 is a very peculiar member of the Carbonic Anhydrase (CA) family. It has been the first enzyme to show an efficient utilization of Cd(II) ions in Nature and a unique adaptation capability to live on the surface ocean. Indeed, in this environment, which is extremely depleted in essential metal ions, CDCA1 can utilize Zn(II) or Cd(II) as catalytic metal to support the metabolic needs of fast growing diatoms. In this paper we demonstrate a further catalytic versatility of this enzyme by using a combination of X-ray crystallography, molecular dynamics simulations and enzymatic experiments. First we identified the CO2 binding site and the way in which this substrate travels from the environment to the enzyme active site. Then, starting from the observation of a structural similarity with the substrate entry route of CS2 hydrolase from Acidanius A1-3, we hypothesized and demonstrated that also CS2 is a substrate for CDCA1. This finding is new and unexpected since until now only few CS2 hydrolases have been characterized, and none of them is reported to have any CO2 hydratase action. The physiological implications of this supplementary catalytic activity still remain to be unveiled. We suggest here that it could represent another ability of diatoms expressing CDCA1 to adapt to the external environment. Indeed, the ability of this enzyme to convert CS2 could represent an alternative source of carbon acquisition for diatoms, in addition to CO2.

Abstract
Prosystemin, originally isolated from Lycopersicon esculentum, is a tomato pro-hormone of 200 aminoacid residues which releases a bioactive peptide of 18 aminoacids called Systemin. This signaling peptide is involved in the activation of defense genes in solanaceous plants in response to herbivore feeding damage. Using biochemical, biophysical and bioinformatics approaches we characterized Prosystemin, showing that it is an intrinsically disordered protein possessing a few secondary structure elements within the sequence. Plant treatment with recombinant Prosystemin promotes early and late plant defense genes, which limit the development and survival of Spodoptera littoralis larvae fed with treated plants.

Abstract
The Mediterranean fruitfly Ceratitis capitata (medfly) is an invasive agricultural pest of high economic impact and has become an emerging model for developing new genetic control strategies as an alternative to insecticides. Here, we report the successful adaptation of CRISPR-Cas9-based gene disruption in the medfly by injecting in vitro pre-assembled, solubilized Cas9 ribonucleoprotein complexes (RNPs) loaded with gene-specific single guide RNAs (sgRNA) into early embryos. When targeting the eye pigmentation gene white eye (we), a high rate of somatic mosaicism in surviving G0 adults was observed. Germline transmission rate of mutated we alleles by G0 animals was on average above 52%, with individual cases achieving nearly 100%. We further recovered large deletions in the we gene when two sites were simultaneously targeted by two sgRNAs. CRISPR-Cas9 targeting of the Ceratitis ortholog of the Drosophila segmentation paired gene (Ccprd) caused segmental malformations in late embryos and in hatched larvae. Mutant phenotypes correlate with repair by non-homologous end-joining (NHEJ) lesions in the two targeted genes. This simple and highly effective Cas9 RNP-based gene editing to introduce mutations in C. capitata will significantly advance the design and development of new effective strategies for pest control management.

Dithiocarbamates effectively inhibit the β-carbonic anhydrase from the dandruff-producing fungus Malassezia globosa. Bioorg Med Chem 2016; 25:1260-1265.

Abstract
A series of dithiocarbamates (DTCs) was investigated for the inhibition of the β-class carbonic anhydrase (CAs, EC 4.2.1.1) from the fungal parasite Malassezia globosa, MgCA, a validated anti-dandruff drug target. These DTCs incorporate various scaffold, among which those of N,N-dimethylaminoethylenediamine, the aminoalcohols with 3-5 carbon atoms in their molecule, 3-amino-quinuclidine, piperidine, morpholine and piperazine derivatives, as well as phenethylamine and its 4-sulfamoylated derivative. Several DTCs resulted more effective in inhibiting MgCA compared to the standard sulfonamide drug acetazolamide (KI of 74μM), with KIs ranging between 383 and 6235nM. A computational approach, involving a homology modeling of the enzyme and docking inhibitors within its active site, helped us rationalize the results. This study may contribute to better understand the inhibition profile of MgCA, and offer new ideas for the design of modulators of activity which belong to less investigated chemical classes, thus potentially useful to combat dandruff and other fungal infections.

Abstract
Carbonic anhydrases (CAs) III and VII are two cytosolic isoforms of the α-CA family which catalyze the physiological reaction of carbon dioxide hydration to bicarbonate and proton. Despite these two enzymes share a 49% sequence identity and present a very similar three-dimensional structure, they show profound differences when comparing the specific activity for CO2 hydration reaction, with CA VII being much more active than CA III. Recently, CA III and CA VII have been proposed to play a new role as scavenger enzymes in cells where oxidative damage occurs. Here, we will examine functional and structural features of these two isoforms giving insights into their newly proposed protective role against oxidative stress.

Abstract
Inhibition of the β-carbonic anhydrases (CAs, EC 4.2.1.1) from pathogenic fungi (Cryptococcus neoformans, Candida albicans, Candida glabrata, Malassezia globosa) and bacteria (three isoforms from Mycobacterium tuberculosis, Rv3273, Rv1284 and Rv3588), as well from the insect Drosophila melanogaster (DmeCA) and the plant Flaveria bidentis (FbiCA1) with the boronic acid peptidomimetic proteosome inhibitor bortezomib was investigated. Bortezomib was a micromolar inhibitor of all these enzymes, with KIs ranging between 1.12 and 11.30μM. Based on recent crystallographic data it is hypothesized that the B(OH)2 moiety of the inhibitor is directly coordinated to the zinc ion from the enzyme active site. The class of boronic acids, an under-investigated type of CA inhibitors, may lead to the development of anti-infectives with a novel mechanism of action, based on the pathogenic organisms CA inhibition.

Abstract
The genome of the newly identified bacterium Enterobacter sp. B13 encodes for a β-class carbonic anhydrases (CAs, EC 4.2.1.1), EspCA. This enzyme was recently cloned, and characterized kinetically by this group (J. Enzyme Inhib. Med. Chem. 2016, 31). Here we report an inhibition study with sulfonamides and sulfamates of this enzyme. The best EspCA inhibitors were some sulfanylated sulfonamides with elongated molecules, metanilamide, 4-aminoalkyl-benzenesulfonamides, acetazolamide, and deacetylated methazolamide (KIs in the range of 58.7-96.5nM). Clinically used agents such as methazolamide, ethoxzolamide, dorzolamide, brinzolamide, benzolamide, zonisamide, sulthiame, sulpiride, topiramate and valdecoxib were slightly less effective inhibitors (KIs in the range of 103-138nM). Saccharin, celecoxib, dichlorophenamide and many simple benzenesulfonamides were even less effective as EspCA inhibitors, with KIs in the range of 384-938nM. Identification of effective inhibitors of this bacterial enzyme may lead to pharmacological tools useful for understanding the physiological role(s) of the β-class CAs in bacterial pathogenicity/virulence.

Abstract
The genome of the pathogenic bacterium Vibrio cholerae encodes for three carbonic anhydrases (CAs, EC 4.2.1.1) belonging to the α-, β- and γ-classes. Here we report and anion inhibition study of the β-CA, VchCAβ with anions and other small molecules which inhibit metalloenzymes. The best VchCAβ anion inhibitors were sulfamide, sulfamate, phenylboronic acid and phenylarsonic acid, which showed KIs in the range of 54-86μM. Diethyldithiocarbonate was also an effective VchCAβ inhibitor, with an inhibition constant of 0.73mM. The halides, cyanate, thiocyanate, cyanide, bicarbonate, carbonate, nitrate, nitrite, stannate, selenate, tellurate, divanadate, tetraborate, perrhenate, perruthenate, peroxydisulfate, selenocyanide, trithiocarbonate, and fluorosulfonate showed affinity in the low millimolar range, with KIs of 2.3-9.5mM. Identification of selective inhibitors of VchCAβ (over the human CA isoforms) may lead to pharmacological tools useful for understanding the physiological role(s) of this under-investigated enzyme.

Abstract
Imine derivatives were obtained by condensation of sulfanilamide with substituted aromatic aldehydes. The Schiff bases were thereafter reduced with sodium borohydride, leading to the corresponding amines, derivatives of 4-sulfamoylphenyl-benzylamine. These sulfonamides were investigated as inhibitors of the human carbonic anhydrase (hCA, EC 4.2.1.1) isoforms hCA I and II (cytosolic isozymes), as well as hCA IX and XII (transmembrane, tumor-associated enzymes). We noted that the compounds incorporating secondary amine moieties showed a better inhibitory activity against all CA isozymes compared to the corresponding Schiff bases. Low nanomolar CA II, IX and XII inhibitors were detected, whereas the activity against hCA I was less potent. The secondary amines incorporating sulfonamide or similar zinc-binding groups, poorly investigated chemotypes for designing metalloenzyme inhibitors, may offer interesting opportunities in the field due to the facile preparation and possibility to explore a vast chemical space.

Abstract
The genome of the fungal parasite Malassezia globosa, the causative agent of dandruff, contains a single gene annotated as encoding a carbonic anhydrase (CAs, EC 4.2.1.1) belonging to the β-class (MgCA). In an earlier work (J. Med. Chem. 2012, 55, 3513) we have validated this enzyme as an anti-dandruff drug target, reporting that sulfonamide inhibitors show in vitro and in vivo effects, in an animal model of Malassezia infection. However, few classes of compounds apart the sulfonamides, were investigated for their activity against MgCA. Here we present an anion inhibition study of this enzyme, reporting that metal complexing anions such as cyanate, thiocyanate, cyanide, azide are weak MgCA inhibitors (KIs ranging between 6.81 and 45.2 mM) whereas bicarbonate (KI of 0.59 mM) and diethyldithiocarbamate (KI of 0.30 mM) together with sulfamide, sulfamate, phenylboronic acid and phenylarsonic acid were the most effective inhibitors detected so far, with KIs ranging between 83 and 94 μM. This study may help a better understanding of the inhibition profile of this enzyme and may offer the possibility to design new such modulators of activity belonging to different chemical classes.

Protonography, a powerful tool for analyzing the activity and the oligomeric state of the γ-carbonic anhydrase identified in the genome of Porphyromonas gingivalis. Bioorg Med Chem 2015; 23:3747-50.

Abstract
Carbonic anhydrases (CAs, EC 4.2.1.1) are metalloenzymes, mostly containing zinc within their active site, which catalyze a simple but physiologically relevant reaction in all life kingdoms, carbon dioxide hydration to bicarbonate and protons. Six CA classes (α, β, γ, δ, ζ and η) and multiple CA isoforms evolved in organisms all over the phylogenetic tree, for facing the need to efficiently convert high amounts of CO2 to its hydration products. These enzymes are thus involved in many physiologic processes, such as photosynthesis, respiration, CO2 transport, electrolyte secretion in many tissues/organs; biosynthetic reactions (gluconeogenesis, lipogenesis, ureagenesis), etc. Recently, our group reported a new technique to assay CA activity on SDS-PAGE gels, named 'protonography' due to its similarity to zymography. By using protonography, the conversion of CO2 into protons can be visualized as a yellow band on a polyacrylamide gel. By using this technique we demonstrated the possibility to detect activity of the α-CA from Vibrio cholerae as well as the β- and γ-CAs present in Escherichia coli extracts. Furthermore, the activity of the newly discovered η-class enzyme from Plasmodium falciparum has also been evidenced with protonography, illustrating its wide use. Here we show that protonography can be also useful to reveal the oligomeric state of the γ-CA identified in the genome of the bacterial parasite colonizing the oral cavity, Porphyromonas gingivalis, possibly allowing for a simple and efficient diagnostic method.

Abstract
The oral pathogenic bacterium Porphyromonas gingivalis, encodes for two carbonic anhydrases (CAs, EC 4.2.1.1) one belonging to the γ-class (PgiCA) and another one to the β-class (PgiCAb). This last enzyme has been cloned and characterized here for its inhibition profile with the main class of CA inhibitors, the sulfonamides. Many of the clinically used sulfonamides as well as simple aromatic/heterocyclic sulfonamides were ineffective as PgiCAb inhibitors whereas better inhibition was observed with simple derivatives such as sulfanilamide, metanilamide, 4-aminoalkylbenzenesulfonamides (KIs of 364-475nM). The halogenosulfanilamides incorporating heavy halogens, 4-hydroxy- and 4-hydroxyalkyl-benzenesulfonamides, were also micromolar, ineffective PgiCAb inhibitors. The best inhibitors of the β-class enzyme were acetazolamide and ethoxzolamide, with KIs of 214-280nM. Interestingly, the γ-class enzyme was much more sensitive to sulfonamide inhibitors compared to the β-class one, PgiCAb. Identification of potent and possibly selective inhibitors of PgiCAb/PgiCA may lead to pharmacological tools useful for understanding the physiological role(s) of these enzymes, since this bacterium is the main causative agent of periodontitis and few treatment options are presently available.

Abstract
The model organism for the investigation of symbiotic nitrogen fixation in legumes Lotus japonicus encodes two carbonic anhydrases (CAs, EC 4.2.1.1) belonging to the α-class, LjCAA1 and LjCAA2. Here we report the kinetic characterization and inhibition of these two CAs with inorganic and complex anions and other molecules interacting with zinc proteins, such as sulfamide, sulfamic acid, and phenylboronic/arsonic acids. LjCAA1 showed a high catalytic activity for the CO2 hydration reaction, with a k(cat) of 7.4∗10(5) s(-1) and a k(cat)/K(m) of 9.6∗10(7) M(-1) s(-1) and was inhibited in the low micromolar range by N,N-diethyldithiocarbamate, sulfamide, sulfamic acid, phenylboronic/arsonic acid (K(I)s of 4-62 μM). LjCAA2 showed a moderate catalytic activity for the physiologic reaction, with a k(cat) of 4.0∗10(5) s(-1) and a k(cat)/K(m) of 4.9∗10(7) M(-1) s(-1). The same anions mentioned above for the inhibition of LjCAA1 showed the best activity against LjCAA2 (K(I)s of 7-29 μM). Nitrate and nitrite, anions involved in nitrogen fixation, showed lower affinity for the two enzymes, with inhibition constants in the range of 3.7-7.0 mM. Halides and sulfate also behaved in a distinct manner towards the two enzymes investigated here. As LjCAA1/2 participate in the pH regulation processes and CO2 metabolism within the nitrogen-fixing nodules of the plant, our studies may shed some light regarding these complex biochemical processes.
