A set of chiral crystal solids with odd and even numbers of carbon atoms based on S-naproxen, ester S-naproxen-R1 (R1 = H, methyl, ethyl, n-propyl, n-butyl, and n-amyl), has been prepared, alternatively crystallizing in the space groups P21 and P212121, respectively, which shows the multi odd-even effects on cell parameters, melting points, and optical properties.

The discovery of new antimicrobial molecules is crucial for combating drug-resistant bacterial and fungal infections that pose a dangerous threat to human health. In the current research, we applied a molecular hybridization approach to synthesize original thiosemicarbazide-triazole derivatives starting from (S)-naproxen (7a–7k). After structural characterization using FT-IR, 1H-NMR, 13C-NMR, and HR-MS, the obtained compounds were screened for their antimicrobial activities against Staphylococcus aureus ATCC 29213, Escherichia coli ATCC 25922, Candida albicans ATCC 10231 and their isolates, as well. Although all compounds were found to be moderate antimicrobial agents, in general, their antibacterial activities were better than antifungal effects. Among the tested compounds, 7j carrying nitrophenyl group on the thiosemicarbazide functionality represented the best MIC value against S. aureus isolate. Finally, molecular docking studies were performed in the active pocket of S. aureus flavohemoglobin to rationalize the obtained biological data.

Oxidative stress and inflammation are two conditions that coexist in many multifactorial diseases such as atherosclerosis and neurodegeneration. Thus, the design of multifunctional compounds that can concurrently tackle two or more therapeutic targets is an appealing approach. In this study, the basic NSAID structure was fused with the antioxidant moieties 3,5-di-tert-butyl-4-hydroxybenzoic acid (BHB), its reduced alcohol 3,5-di-tert-butyl- 4-hydroxybenzyl alcohol (BHBA), or 6-hydroxy-2,5,7,8-tetramethylchromane-2-carboxylic acid (Trolox), a hydrophilic analogue of α-tocopherol. Machine learning algorithms were utilized to validate the potential dual effect (anti-inflammatory and antioxidant) of the designed analogues. Derivatives 1-17 were synthesized by known esterification methods, with good to excellent yields, and were pharmacologically evaluated both in vitro and in vivo for their antioxidant and anti-inflammatory activity, whereas selected compounds were also tested in an in vivo hyperlipidemia protocol. Furthermore, the activity/binding affinity of the new compounds for lipoxygenase-3 (LOX-3) was studied not only in vitro but also via molecular docking simulations. Experimental results demonstrated that the antioxidant and anti-inflammatory activities of the new fused molecules were increased compared to the parent molecules, while molecular docking simulations validated the improved activity and revealed the binding mode of the most potent inhibitors. The purpose of their design was justified by providing a potentially safer and more efficient therapeutic approach for multifactorial diseases.
