Abstract:

<p>Background: The plants of high phenolic contents are perfect antioxidant and anti-inflammatory agents and participate in biological studies as effective agents towards different cancer cell lines. </P><P> Objective: To investigate the antioxidant, anti-inflammatory, and cytotoxic activities of the hydromethanolic leaf extract of Jasminum multiflorum (Burm. f.) Andrews. (J. multiflorum), and phenolic profiling of the extract. </P><P> Methods: The antioxidant activity for the extract was estimated using &#946;-Carotene-linoleic and Ferric Reducing Antioxidant Power (FRAP) assays. The anti-inflammatory activity was evaluated by histamine release assay. Cytotoxicity of J. multiflorum was performed using a neutral red uptake assay towards breast cancer (MCF-7) and colorectal cancer (HCT 116) cell lines. Phenolic profiling of the leaves was characterized using high performance liquid chromatography coupled to photodiode array detector-mass spectroscopy-mass spectroscopy (HPLC-PDA-MS/MS), and chromatographic isolation and identification of the isolated compounds were performed using spectroscopic and NMR data, and virtual docking was performed to the isolated compounds against HSP90 (HEAT SHOCK PROTEIN 90). </P><P> Results: At a concentration of 75 μg mL-1, J. multiflorum extract showed high antioxidant power; 68.23±0.35 % inhibition and 60.30±0.60 a TEAC (μmol Trolox g-1) for &#946;-Carotene-linoleic assay and FRAP assay; respectively, and possessed anti-inflammatory activity with IC50 67.2 μg/ml. J. multiflorum showed high cytotoxic activity with IC50 of 24.81 μg/ml and 11.38 μg/ml for MCF-7 and HCT 116 cell lines, respectively. HPLC-PDA-MS/MS analysis tentatively identified 39 compounds; major compounds are secoiridoid glycosides, kaempferol, and quercetin glycosides, in addition to simple phenylethanoid compounds. Isolation of active metabolites was performed and led to the isolation and identification of four compounds. On the basis of docking study using HSP90 legend, kaempferol neohesperidoside showed a high cytotoxic potential supported by a high affinity score towards HSP90 legend protein. </P><P> Conclusion: Jasminum multiflorum is a good candidate to isolate cytotoxic agents.</p>
