Biological Evaluation and Molecular Docking Studies of Novel Aza-Acyclic Nucleosides as Putative Antimicrobial, Anticancer, and Antioxidant Agents

This study aimed to synthesize new aza-acyclic nucleosides (aza-acyclovir) and evaluate the efficacy of these synthetic compounds as potential antimicrobial, anticancer, and antioxidant agents. We prepared two novel aza-acyclic nucleosides via two reactions. The first reaction involved trichloroisocyanuric acid and dibenzosulphonyl diethylamine, and the second reaction involved trichloroisocyanuric acid and diethanolamine. We then used one-dimensional nuclear magnetic resonance (NMR) spectroscopy, two-dimensional NMR spectroscopy, infrared spectroscopy, and mass spectrometry to determine the structures of the resulting compounds. In this regard, we first tested the antimicrobial activity of these compounds against various bacteria, including Bacillus cereus, B. subtilis, Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli, Proteus mirabilis, and Pseudomonas aeruginosa, and against fungal pathogens, including Aspergillus fumigatus, Candida tropicalis, and Alternaria solani. Next, the precise mode for the interaction between synthesized aza-acyclic nucleosides and the target protein 8HQ5 was elucidate using molecular docking analysis. Subsequently, we tested the synthesized compounds for putative anticancer activity at different concentrations (i.e., 12.5, 25, 50, 100, and 200 µg/mL) against A549 cell (Human epithelial lung carcinoma) and human umbilical vein endothelial cell (HUVEC) lines. In addition, compounds antioxidant activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl-based and cupric reducing antioxidant capacity-based methods at different concentrations (i.e., 31.25, 62.5, 125, 250, and 500 µg/mL). Results revealed that both aza-acyclic nucleosides inhibited both bacterial and fungal strains, although toxicity toward bacterial strains was generally greater than toward fungal strains. We also observed that the molecular docking results were consistent with the results of in vitro antimicrobial assessments. Further, both aza-cyclic nucleosides exhibited cytotoxic effects against both the A549 cell and HUVEC lines. Despite exhibiting lower radical scavenging activity than ascorbic acid (an antioxidant compound used as a standard), Compound 1 from the novel synthetic aza-acyclic nucleosides showed a higher reduction capacity, which was dose-dependent. Overall, we report newly synthesized compounds that show promising antimicrobial, anticancer, and antioxidant effects. © 2025 Elsevier B.V., All rights reserved.

ERUCA SATIVA MILL SEEDS OIL ALLEVIATES HYPERLIPIDEMIA AND NONALCOHOLIC FATTY LIVER DISEASE IN SYRIAN HAMSTER
(Journal of Animal & Plant Sciences, 2022) Alhilal, M.; Sulaiman, Y.A.M.; Subuh, A.M.; Habra, N.; Alhilal, S.
The impact of oils rich in long chain monounsaturated fatty acids (LCMUFA) against hyperlipidemia and non-alcoholic fatty liver disease (NAFLD) has been inadequately described. In addition, the chemical solvents and the high temperature used in vegetable oils extraction process from seeds cause severe loss of many vital compounds. So the goal of this paper was to examine the effect of cold pressed Eruca sativa Mill seeds oil (ESSO), as a source of LCMUFA, on hyperlipidemia and NAFLD in Syrian hamster. The ESSO content of fatty acids was analyzed using chromatographic methods. Fifty two (52) healthy male golden Syrian hamsters used in this experiment were randomly divided into 4 groups (Completely Randomized Design). Negative control group, CHD group, positive control group and ESSO group. This experiment was achieved in two periods. The first period continued 4 weeks, in which hyperlipidemia and NAFLD were induced in CHD, positive control and ESSO groups through feeding on a hyperlipidemic diet. The second period also lasted 4 weeks, in which ESSO was orally gavaged at 2 g/kg of the body weight daily to animals of ESSO group. The levels of total cholesterol (TC), triglycerides, HDL-C and glucose and the activities of ALT, AST, ALP, LDH and CK were analysed in the serum. One way analysis of variance (ANOVA) followed by Duncan's multiple range test was used for statistical analysis. The consumption of hyperlipidemic diet for 4 weeks caused a significant raise (P<0.05) of triglycerides, glucose, ALT, AST, LDH, CK and a significant reduction (P<0.05) of the HDL-C/TC ratio, at the same time created lipid accumulation in liver cells in CHD, positive control and ESSO groups in comparison with negative control group at the end of the first period. These negative influences were alleviated in ESSO group by administration of ESSO at the end of second period. In conclusion, The examined cold pressed ESSO has effective hypolipidemic and hepatoprotective effects in Syrian hamsters with hyperlipidemia and NAFLD.
