Abstract
Metabolomics, the study of small-molecule metabolites within biological systems, has become a potent instrument for understanding cellular processes. Despite its profound insights into health, disease, and drug development, identifying the protein partners for metabolites, especially dietary phytochemicals, remains challenging. In the present study, we introduced an innovative in silico, structure-based target prediction approach to efficiently predict protein targets for metabolites. We analyzed 27 blood serum metabolites from nutrition intervention studies' blueberry-rich diets, known for their health benefits, yet with elusive mechanisms of action. Our findings reveal that blueberry-derived metabolites predominantly interact with Carbonic Anhydrase (CA) family proteins, which are crucial in acid-base regulation, respiration, fluid balance, bone metabolism, neurotransmission, and specific aspects of cellular metabolism. Molecular docking showed that these metabolites bind to a common pocket on CA proteins, with binding energies ranging from -5.0 kcal/mol to -9.0 kcal/mol. Further molecular dynamics (MD) simulations confirmed the stable binding of metabolites near the Zn binding site, consistent with known compound interactions. These results highlight the potential health benefits of blueberry metabolites through interaction with CA proteins.

Abstract
In the relentless search for new cancer treatments, organoselenium compounds, and carbonic anhydrase (CA) inhibitors have emerged as promising drug candidates. CA isoforms IX and XII are overexpressed in many types of cancer, and their inhibition is associated with potent antitumor/antimetastatic effects. Selenium-containing compounds, particularly selenols, have been shown to inhibit tumour-associated CA isoforms in the nanomolar range since the properties of the selenium atom favour binding to the active site of the enzyme. In this work, two series of selenoesters (1a-19a and 1b-19b), which gathered NSAIDs, carbo/heterocycles, and fragments from natural products, were evaluated against hCA I, II, IX, and XII. Indomethacin (17b) and flufenamic acid (19b) analogs exhibited selectivity for tumour-associated isoform IX in the low micromolar range. In summary, selenoesters that combine NSAIDs with fragments derived from natural sources have been developed as promising nonclassical inhibitors of the tumour-associated CA isoforms.

Abstract
Carbonic anhydrases (CAs) are drug targets for a variety of diseases. While many clinically relevant CA inhibitors are sulfonamide-based, novel CA inhibitors are being developed that incorporate alternative zinc-binding groups, such as carboxylic acid moieties, to develop CA isoform-specific inhibitors. Here, the X-ray crystal structure of human CA II (hCA II) in complex with the carboxylic acid ibuprofen [2-(4-isobutylphenyl)propanoic acid, a common over-the-counter nonsteroidal anti-inflammatory drug] is reported to 1.54 Å resolution. The binding of ibuprofen is overlaid with the structures of other carboxylic acids in complex with hCA II to compare their inhibition mechanisms by direct or indirect (via a water) binding to the active-site zinc. Additionally, enzyme-inhibition assays using ibuprofen, nicotinic acid and ferulic acid were performed with hCA II to determine their IC50 values and were compared with those of other carboxylic acid binders. This study discusses the potential development of CA inhibitors utilizing the carboxylic acid moiety.

Abstract
We report aryl sulfonamide inhibitors of human carbonic anhydrase (hCA; EC 4.2.1.1) enzymes containing short ureido alkoxy tails. The inhibition potency of such compounds was investigated in vitro on the major hCA isoforms (i.e. I, II, IX, and XII). A selection of the most potent inhibitory derivatives against the hCA IX isoform (i.e. 5a, 5c, and 6c) was studied, and their binding modes on either hCA II and IX-mimic isoform were assessed by X-ray crystallography on the corresponding ligand/protein adducts. This study adds to the field of developing hCA inhibitors at molecular level the critical interactions governing ligand selectivity.

Abstract
A series of benzoselenoates has been prepared and their inhibitory properties against the most relevant human Carbonic Anhydrases (CAs) isoforms, among which hCA I, II, IV, VII, IX, and XII were investigated. These inhibitors were designed considering the carboxylates and mono-/dithiocarbamates as lead and led to the observation that the COSe- is a new zinc-binding group (ZBG) for metalloenzymes possessing zinc ions at their active site. The substitution pattern on aromatic ring of the benzoselenoates is the crucial structural element influencing selectivity towards various isoforms. We elucidated the binding mode of benzoselenoates to hCA I and hCA II by using X-ray crystallography. The negatively charged selenium atom from the new ZBG was observed coordinated to the zinc ion from the CA active site at a distance of 2.30-2.40 Å from it. Overall, these data might be useful for the development of new inhibitors with higher selectivity and efficacy for various hCAs.

Abstract
To date, catechols have been only poorly investigated as carbonic anhydrase (CA) inhibitors. 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".

Abstract
Carbonic anhydrase II (CAII) is a metalloenzyme that catalyzes the reversible hydration/dehydration of CO2/HCO3−. In addition, CAII is attributed to other catalytic reactions, including esterase activity. Aspirin (acetyl-salicylic acid), an everyday over-the-counter drug, has both ester and carboxylic acid moieties. Recently, compounds with a carboxylic acid group have been shown to inhibit CAII. Hence, we hypothesized that Aspirin could act as a substrate for esterase activity, and the product salicylic acid (SA), an inhibitor of CAII. Here, we present the crystal structure of CAII in complex with SA, a product of CAII crystals pre-soaked with Aspirin, to 1.35Å resolution. In addition, we provide kinetic data to support the observation that CAII converts Aspirin to its deacetylated form, SA. This data may also explain the short half-life of Aspirin, with CAII so abundant in blood, and that Aspirin could act as a suicide inhibitor of CAII.
