So, there is an urgent need to explore efficient broad-spectrum antimicrobial compounds that can prevent and eradicate biofilms. In this work, we propose the use of simple, economical, and low molecular weight amino acid-based surfactants to fight against AR. These compounds consist of one amino acid (phenylalanine or tryptophan) linked through an amide bond to one C<sub>8</sub>–C<sub>14</sub> alkyl chain. Surface tension measurements and SAXS analysis show the formation of prolate ellipsoidal micelles at low critical micelle concentration (CMC around 0.2–11 mM). These compounds exhibit antifungal activity against a broad-spectrum Candida strain, with the C<sub>14</sub> derivatives being the most efficient agents with MIC values of 16–32 µM. They can disrupt mature <em>C. albicans</em> biofilms at very low concentrations, and the long-chain derivatives can easily condense DNA. Interestingly, these surfactants exhibited lower aquatic toxicity and better biodegradability than the widely used quaternary ammonium cationic surfactants (QAC<sub>S</sub>). This is an important property given that non-biodegradable compounds lead to persistence in the environment, increasing the proliferation of antimicrobial resistance. The results obtained in this work allow for establishing a structure–activity relationship that can help in designing new biodegradable and biocompatible antimicrobial surfactants. Moreover, given their biological and physicochemical properties, these surfactants can be an interesting alternative to the existing antimicrobials for medical and industrial applications.</div></div>","PeriodicalId":371,"journal":{"name":"Journal of Molecular Liquids","volume":"429 ","pages":"Article 127620"},"PeriodicalIF":5.3,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143869420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This distribution reduces attraction between ion pairs and balances the energy between them, facilitating the formation of an IL. In this work, we designed the ILs containing the natural anions and cations. In the designed ILs, the anions contain various amino acids and sugars, and the cation contains methylated DNA base adenine. Our study has focused on intramolecular hydrogen bonding (H-bond) within the anion and intermolecular H-bond between methylated adenine cation and the various anions. Our objective in creating these structures is to investigate H-bonds’ influence on the negative charge distribution in the anion and to explore the anomeric effect on the stability of the cation in the designed ILs. In particular, using quantum mechanics (QM) calculations, we examined how intermolecular H-bonds affect the interaction energy between the ions in our newly designed ILs. At the same time, molecular dynamics (MD) simulations were utilized to validate the QM results. The QM average interaction energy (Δ<em>E<sub>int</sub></em>) between the anion and cation of the designed ILs is −73.39 kcal/mol, consistent with the Δ<em>E<sub>int</sub></em> typically reported for the common ILs.

Innovative sorbents are expected to foster green technologies, in which no adverse environmental influences are included. We herein report classical molecular dynamics (MD) simulations to evaluate the absorption of carbon dioxide (CO<sub>2</sub>) and hydrogen sulfide (H<sub>2</sub>S) by the newly developed deep eutectic solvents (DESs). The novel DESs represent binary mixtures of menthol (MEN) and diamines (hexyl-ethylene-diamine, HEX, and nonyl-ethylene-diamine, NON,). The simulations revealed that both DESs exhibit a higher affinity to CO<sub>2</sub> rather than to H<sub>2</sub>S due to larger partial atomic electrostatic charges on the oxygen atoms. The increase in pressure resulted in a linear boost in the gas capacities of HEX/MEN and NON/MEN. In turn, no synergistic effect was detected while investigating CO<sub>2</sub>/H<sub>2</sub>S simultaneous absorption. The performance of HEX/MEN as an absorbent is somewhat higher as compared to that of NON/MEN in the case of H<sub>2</sub>S and within the computation uncertainty in the case of CO<sub>2</sub>. The revealed potential of HEX/MEN and NON/MEN to capture CO<sub>2</sub> and H<sub>2</sub>S suggests that novel interesting gas scavengers were identified and comprehensively characterized.</div></div>","PeriodicalId":371,"journal":{"name":"Journal of Molecular Liquids","volume":"429 ","pages":"Article 127609"},"PeriodicalIF":5.3,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143859427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
