Elucidating the antimicrobial and anticarcinogenic potential of methanolic and water extracts of edible <i>Tragopogon coelesyriacus</i> Boiss.

Abstract Tragopogon coelesyriacus is a pharmacotherapeutic herbaceous plant belonging to the Asteraceae family and consumed as a vegetable. Here, the methanolic and water extracts of T. coelesyriacus were obtained from its aboveground parts (stem, leaves, and flowers), and the phytochemical potentials were investigated by LC‐HRMS (liquid chromatography–high resolution mass spectrometry) analysis for the first time. The antibacterial, antifungal, and anticarcinogenic activities of T. coelesyriacus extracts were investigated using experimental and in silico methods. T. coelesyriacus methanol extract revealed remarkable inhibitory activity against Staphylococcus aureus , Pseudomonas aeruginosa , and Klebsiella pneumonia (MICs = 0.83, 1.67, and 1.67 mg/mL, respectively) compared to Escherichia coli and Enterobacter aerogenes (MIC = 53.3 mg/mL). Inhibitory effects of T. coelesyriacus methanolic extracts were also observed in all Candida species tested, with the highest inhibition on Candida krusei (MIC = 0.83 mg/mL), whereas no inhibitory effect was identified from the water extract. Additionally, both T. coelesyriacus methanolic (IC50 = 86 μg/mL) and water (IC50 = 92 μg/mL) extracts revealed significant selective anticarcinogenic effects on AR42J pancreatic cancer cells. HeLa and MDA‐MB‐231 cells were, however, more resilient to methanol and water extract, respectively. In silico analyses further elucidated the noteworthy antibacterial potential of keracyanin chloride on S. aureus MurB enzyme and the remarkable inhibitory potential of naringin on FYN kinase specific for pancreatic cancer (AR42J) development. In conclusion, T. coelesyriacus phytochemicals with antibacterial, antifungal, and anticancer properties were revealed for the first time, and molecular docking studies on potential targets confirmed good agreement with experimental findings. Therefore, the current studies on T. coelesyriacus provide the basis for investigating new pharmaceutical potentials of other Tragopogon members.
