Title Anti-inflammatory and anti-proliferative activities of the wild edible cruciferous: Diplotaxis simplex.
Journal Pharm Biol
Abstract Context The present study deals with new biological properties of the wild edible Diplotaxis simplex (Viv.) Spreng (Brassicaceae). Objectives The current study evaluates the antioxidant, the anti-inflammatory and the anti-cancer properties of ethyl acetate and ethanol extracts from D. simplex flowers. Materials and methods The anti-proliferative activity of the extracts (10-70 μg/mL) was assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) against human colon cancer cell line Caco-2. The anti-inflammatory potential was evaluated by the inhibitory effect of the extracts (1.5-7.5 mg/mL) on phospholipase A2 activity as well as on carrageenan-induced paw oedema in mice. Extracts (200 mg/kg) or indomethacin (50 mg/kg) as positive control were injected intraperitoneally for albino mice prior to the induction of the oedema by carrageenan. Antioxidant activities were investigated using various complementary methods. Results Flower extracts contained a high level of polyphenolics (17.10-52.70 mg GAE/g) and flavonoids (74.20-100.60 mg QE/g), which correlate with its appreciable antioxidant potential in β-carotene peroxidation (IC50 value: 12.50-27.10 μg/mL), DPPH(•) radical-scavenging (IC50 value: 0.20-0.40 mg/mL), Fe(3+ )reducing (EC50 value: 0.10-0.14 mg/mL) and Fe(2+ )chelating (IC50 value: 0.20-0.60 mg/mL) assays. These extracts were effective in inhibiting cancer cell growth (IC50 value: 62.0-63.25 μg/mL). Besides, the ethyl acetate extract inhibited phospholipase A2 activity (IC50 value: 2.97 mg/mL) and reduced the paw oedema in mice (from 0.38 ± 0.01 to 0.24 ± 0.01 cm), 4 h post-carrageenan challenge. Conclusion These data suggest that D. simplex may be useful as a candidate in the treatment of inflammation and the colon cancer.
