This study explored the chemical profile of the aerial parts of Ononis spinosa and further investigated its biological activities. Chemical profiling of the extract revealed the presence of 63 different compounds: phenolic acids, flavonoid glycosides and aglycones, isoflavonoid glycosides and aglycones, and other related compounds. Our results revealed that the extract was active against 8 strains of free floating bacteria. It showed anti-biofilm potential against Staphylococcus aureus and was able to supress the production of staphyloxanthin in S. aureus at sub-minimal inhibitory concentrations. Its antioxidant activity was evaluated by using several assays (phosphomolybdenum, DPPH, ABTS, CUPRAC, FRAP, and metal chelating assay), which showed that the extract exhibited a dose dependent activity. Inhibition of AChE, BChE, amylase, glucosidase and tyrosinase was achieved by the extract, demonstrating its anti-enzymatic activity. The antiproliferative potential of the extract towards human cancer cell lines (HepG2, MCF-7, SiHa and A172) was determined by using the crystal violet assay. Ki67, a marker of proliferation was downregulated in the A172 glioblastoma cell line.
Ononis spinosa L. is a plant traditionally used as folk remedy. There are numerous studies regarding chemical constituents and health beneficial properties of Ononidis Radix. The following study was designed to investigate chemical composition and antifungal potential of the methanolic extract obtained from the O. spinosa L. herb. Chemical analyses regarding phenolic compounds of O. spinosa were performed by liquid chromatography with mass spectrometry (LC-DAD-ESI/MSn). Antifungal activity, antibiofilm properties and antifungal mode of action of the extract were evaluated, as well as cytotoxicity. Chemical analyses revealed the presence of flavonoids, isoflavonoids and phenolic acids in O. spinosa, with kaempherol-O-hexoside-pentoside being the most abundant compound (5.1 mg/g extract). Methanolic extract was active against all of the tested microfungi with Penicillium aurantiogriseum being the most sensitive to the extract inhibitory effect at 0.02 mg/mL; and effectively inhibited biofilms formed by Candida strains. Minimum fungicidal concentrations of extract rose in the presence of ergosterol and leakage of cellular components was detected. The extract showed no cytotoxicity to human gingival fibroblast (HGF-1) cells. This study significantly contributes to overall knowledge about medicinal potential of O. spinosa herbal extract and enlightens previously unrevealed properties. O. spinosa aerial parts seem to be an interesting candidate for the development of antifungal preparations, non-toxic to human cells.
Glioblastoma (GBM) is the most common and highly lethal type of brain tumor, with poor survival despite advances in understanding its complexity. After current standard therapeutic treatment, including tumor resection, radiotherapy and concomitant chemotherapy with temozolomide, the median overall survival of patients with this type of tumor is less than 15 months. Thus, there is an urgent need for new insights into GBM molecular characteristics and progress in targeted therapy in order to improve clinical outcomes. The literature data revealed that a number of different signaling pathways are dysregulated in GBM. In this review, we intended to summarize and discuss current literature data and therapeutic modalities focused on targeting dysregulated signaling pathways in GBM. A better understanding of opportunities for targeting signaling pathways that influences malignant behavior of GBM cells might open the way for the development of novel GBM-targeted therapies.
