Background:Research into oxidative stress, cancer, and natural products revealed
promising avenues for therapeutic intervention. Natural products are considered potent pharmaceuticals in combating oxidative stress and its relationship with cancer.Methods:This study was carried out to evaluate the chemical profile and antioxidant activities using
DPPH, ABTS, Phenanthroline, Cupric, Phosphomolybdenum, FRAP, Hydroxyl, Iron chelation in
vitro assays, and anticancer properties by MTT method of Cistus creticus extracts. The chemical
composition was determined using the LC/MS-MS technique. Therefore, in silico methods, particularly molecular docking and dynamic simulation were applied for molecular interaction analysisResults:The obtained results revealed a wide variety of phenolic compounds in all studied fractions, in their qualitative and quantitative distribution. In most antioxidant assays, the butanol and
ethyl acetate extracts exhibited the most effective effects, followed by the aqueous extract, while
the petroleum ether and chloroform fractions exhibited much lower activity in comparison with
standards. In parallel, ethyl acetate, n-butanol, and chloroform extracts exhibited potent antiproliferative activity against T47D and A549 cell lines, while the aqueous extract showed an IC50 in the
range of mg/ml. Moreover, the analysis of interactions identified compounds against particular
targets in studied cell lines using molecular docking showed a great affinity, especially for the
ligands Hesperidin, Luteolin-7-O-glucoside and Rutin. Also, the molecular dynamic simulation of
the interacting complexes Hesperidin-mTOR, Lutin-EGFR and Apigenin-HER2 revealed precise
interaction, providing insights into their stability and dynamic behavior. FurtheConclusion:These findings confirmed the potential of Algerian Cistus creticus L. leaf extracts as
promising therapeutic molecules for combating oxidative stress and cancer.
