Antibacterial and antioxidant activities of extracts and isolated compounds from the roots extract of Cucumis prophetarum and in silico study on DNA gyrase and human peroxiredoxin 5 (original) (raw)

Background Cucumis prophetarum is traditionally used to treat liver and lung disorders, heart failure, diarrhea, gonorrhea, skin infections, intestinal problems and cancer. In the present work, the isolation of two novel compounds along with their antibacterial and antioxidant activities is reported for the first time. Methods Silica gel column chromatography was applied to separate constituents of the roots of C. prophetarum. The structures of isolated compounds were established using 1H NMR, 13C NMR, DEPT-135, COSY, HSQC and HMBC. Agar well diffusion, DPPH assay and ferric thiocyante methods were used for antibacterial, radical scavenging and anti-lipid peroxidation activities, respectively. AutoDock Vina open source program was used for molecular docking analysis. Results Evaluation of the in vitro antibacterial activity of the constituents against S. aureus, B. subtilis, E. coli and S. thyphimurium revealed that the hexane extract were active against E. coli with IZ of 15.0 ± 1....
