Study of Chalcogen Aspirin Derivatives with Carbonic Anhydrase Inhibitory Properties for Treating Inflammatory Pain. ACS Med Chem Lett 2024; 15:1559-1565. [PMID: 39291024 PMCID: PMC11403731 DOI: 10.1021/acsmedchemlett.4c00284] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2024] [Revised: 08/02/2024] [Accepted: 08/08/2024] [Indexed: 09/19/2024] Open
Abstract
Carbonic anhydrase (CA) inhibitors represent intriguing tools for treating pain. This study aims at studying the pharmacological profile of chalcogen bioisosteres of aspirin, as inhibitors of CA isoforms (hCA I, II, IV, VII, IX, and XII). Our results show that selenoaspirin (5) displayed markedly superior inhibitory potency across all tested isoforms compared to thioaspirin (7) and aspirin, with a strong selectivity against the isoform CA IX. X-ray crystallography confirmed that both compounds bind effectively within the active site of hCA II, revealing unique structural characteristics compared to those of aspirin. In a preclinical model of inflammatory pain, compound 7 exhibited a longer lasting antihyperalgesic effect than aspirin, though with a lower potency. Conversely, compound 5 exhibited both lower potency and efficacy than aspirin in reducing pain, which entailed both adverse effects. Nevertheless, the therapeutic potential of chalcogen-based aspirin derivatives as novel CA inhibitors deserves to be further explored for clinical applications.

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
Differently substituted β-hydroxy- and β-amino dialkyl and alkyl-aryl tellurides and selenides have been prepared through ring-opening reactions of epoxides and aziridines with selenium- or tellurium-centered nucleophiles. The antioxidant properties and the cytotoxicity of such compounds have been investigated on normal human dermal fibroblasts. Most of the studied compounds exhibited a low cytotoxicity and a number of them proved to be non-toxic, not showing any effect on cell viability even at the highest concentration used (100 μM). The obtained results showed a significant antioxidant potential of the selected organotellurium compounds, particularly evident under conditions of exogenously induced oxidative stress. The antioxidant activity of selenium-containing analogues of active tellurides has also been evaluated on cells, highlighting that the replacement of Se with Te brought about a significant increase in the peroxidase activity.

Abstract
The one-pot multistep ethyltellurenylation reaction of epoxides with elemental tellurium and lithium triethylborohydride is described. The reaction mechanism was experimentally investigated. Dilithium ditelluride and triethyl borane, formed from elemental tellurium and lithium triethylborohydride, were shown to be the key species involved in the reaction mechanism. Epoxides undergo ring-opening reaction with dilithium ditelluride to afford β-hydroxy ditellurides, which are sequentially converted into the corresponding β-hydroxy-alkyl ethyl tellurides by transmetalation with triethyl borane, reasonably proceeding through the SH2 mechanism.

Abstract
Carbonic anhydrases (CAs, E.C. 4.2.1.1) are metalloenzymes expressed on a variety of cell types. Their overexpression leads to serious pathologies, including cancer. The discovery of a series of selenolesters with high structural diversity as novel CA inhibitors is reported here. These compounds show remarkable in vitro inhibition against a panel of human CA isoforms such as hCA I, II, IX and XII. We observed that they undergo a CA mediated hydrolysis, releasing different active selenol fragments, which act as CA inhibitors. Notably, to the best of our knowledge, this is the first example of an enzyme with selenolesterase activity. In addition, X-ray crystallographic data support the proposed mechanism, proving selenolesters as novel pro-drug inhibitors with potential pharmacological applications.
