The development of new antibiotics capable of combating drug resistance is critical. In various bacteria and plant species, 4-aminobenzoic acid (PABA) is produced and used as a substrate for folate generation. In this study, a new series of PABA analogs were synthesized and evaluated for their antimicrobial activity. Thirteen novel compounds were prepared by linking PABA hydrazide to sulfonate esters <em>via</em> a hydrazone bridge (<strong>4a</strong>–<strong>m</strong>). The structures of these compounds were characterized by ¹H and ¹³C NMR and FT-IR spectroscopy as well as by LC-MS. Following structural characterization, all compounds were tested for their antimicrobial activity against <em>Staphylococcus aureus</em> (ATCC 29213), <em>Enterococcus faecium</em> (ATCC 19434), <em>Escherichia coli</em> (ATCC 25922), <em>Pseudomonas aeruginosa</em> (ATCC 27853), and <em>Candida albicans</em> (ATCC 10231) strains. Four compounds were found to have moderate antimicrobial activity against the <em>P. aeruginosa</em> strain. These compounds, including <strong>4e, 4f, 4g</strong>, and <strong>4m</strong>, containing a hydrazide-hydrazone sulfonate functionality, showed the best MIC value of 64 μg/mL. In addition, synergistic effects of ascorbic acid, salicylic acid, and <em>N</em>-acetyl cysteine (NAC) with synthesized compounds were also investigated. It was observed that the combination of compounds <strong>4f</strong> and <strong>4g</strong> with NAC showed antipseudomonal activity with MIC values of 32 μg/mL and 16 μg/mL, respectively, against the <em>P. aeuriginosa</em> strain. The antimicrobial activity of <strong>4f</strong> and <strong>4g</strong> was enhanced by two folds in combination with NAC. Our findings in this study can be crucial for the development of new potent antimicrobial agents.</p></div>","PeriodicalId":20056,"journal":{"name":"Phosphorus, Sulfur, and Silicon and the Related Elements","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140666913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The investigations had the scope to improve the performance and to elucidate the effect of NHC-CO₂ adducts on the CO₂ cycloaddition reaction. The optimum catalyst DMSNs-Cb-1 and the optimum reaction conditions (200 mg, 100 °C, 10 h) were obtained <em>via</em> thermogravimetric analysis. CO₂ cycloaddition reaction with epoxide DMSNs-Cb-1 can convert CO₂ and epoxide to cyclic carbonate at ambient pressure without solvent and co-catalysts (1 bar, 100 °C). The reaction proceeds with high yield and high conversion frequency (TOF = 27.4 h⁻¹). The prepared catalyst is easily recovered and still has high activity after five cycles of experiments. The excellent catalytic performance of the obtained catalyst can be attributed to the synergy of hierarchical porous structure and NHC-CO₂ adducts acting as CO₂ adsorption sites as well as zwitterionic catalytic sites.
