Abstract:
The present study aimed to investigate the antitumor activity of two extracts obtained from Glinus oppositifolius aerial parts
in MCF-7, A549, PC3 and CACO2 cancer cell lines using the cell viability, cell cycle and DCFH-DA assays. FT-IR analysis
revealed triterpenes and carbohydrates in both extracts and sterols in the ethanolic one. The results from the viability assay
showed that the aqueous extract had a promising cytotoxic effect on CACO2 cells (IC50 = 97.69 ± 2.03 μg/mL). Induction of
apoptosis in CACO2 cells was supported by an increase in the cell population in the sub-G1 phase (55.7 ± 4.03% vs. 8.35 ±
3.85% in control). The DCFH-DA assay revealed that another possible mechanism by which the aqueous extract reduced
CACO2 cell viability was an increase in the intracellular oxidative stress. Further in vitro studies are necessary to elucidate
other mechanisms underlying the antitumor activity and thus to find new possible therapeutic applications of this plant.
