Fig. 3 in Cannabinoid-like meroterpenoids from Peperomia incana

Fig. 3. Cytotoxic effect of compounds 1–10 from Peperomia incana on A549, MDA-MB-231, HeLa, DU 145, 5637, Hep G2, and MIA PaCa-2 cancer cell lines.Cell viability was analyzed by using an XTT assay for cells treated with different concentrations of tested compounds for 48 h. Doxorubicin was used as a positive control. Data are mean ± SEM of three independent experiments (N = 3).

Fig. 6. Quantitative determination of the formation of multidrug resistant S. aureus biofilms in the presence of the compounds 3 (A) and 9 (B), which were obtained after 24 h of growth.The values represent the mean of three independent experiments ± SEM. * indicates statistical significance (p <0.02) in a two tailed Student's t- test. Compound 3 (MIC = 12.7 μM), compound 9 (MIC = 11.5 μM).

Fig. 5 in Determination of phenolic profiles of Herniaria polygama and Herniaria incana fractions and their in vitro antioxidant and anti-inflammatory effects

Fig. 5. Antioxidant activity of the examined fractions isolated from Herniaria incana (HIhfr) and Herniaria polygama (HPfr) in blood plasma under the ONOO - induced oxidative stress in vitro. Protective effects of the examined Herniaria fractions were evaluated based on measurements of protein thiol groups (panel A), 3- nitrotyrosine (panel B), and the ferric reducing ability of plasma (panel C); n = 7, 8, and 9 for –SH groups, 3-nitrotyrosine, and FRAP assay, respectively.

Fig. 2. UHPLC – diode array detector (DAD) and charged aerosol detector (CAD) profiles of the Herniaria polygama phenolic fraction.

Fig. 6 in Determination of phenolic profiles of Herniaria polygama and Herniaria incana fractions and their in vitro antioxidant and anti-inflammatory effects

Fig. 6. Evaluation of protective effects of fractions isolated from Herniaria incana (HIhfr) and Herniaria polygama (HPfr) on the oxidative stress-induced modification of human fibrinogen structure. The figure contains an electrophoretic pattern of fibrinogen samples separated on gradient SDS-PAGE gel (4–20%) under the reducing conditions. Exposure of fibrinogen to ONOO resulted in the formation of high molecular weight protein aggregates (HMW), mainly derived from its Aα-chain and detectable over the fibrinogen pattern. The Herniaria fractions partly reduced these oxidative modifications to fibrinogen molecule; n = 3.

Fig. 7 in Determination of phenolic profiles of Herniaria polygama and Herniaria incana fractions and their in vitro antioxidant and anti-inflammatory effects

Fig. 7. Anti-inflammatory actions of the examined fractions isolated from Herniaria incana (HIhfr) and Herniaria polygama (HPfr) in the concanavalin A-stimulated PBMCs. Effects of the examined plant fractions were evaluated based on measurements of IL-2 (panel A) and TNF-α (panel B) secretion into the cell culture medium. The samples were assayed using the ELISA kits; *p <0.05, **p <0.01, ***p <0.001; n = 4.
