In vitro antioxidant activities of resveratrol, cinnamaldehyde and their synergistic effect against cyadox-induced cytotoxicity in rabbit erythrocytes. Drug and chemical toxicology, 2017, Volume: 40, Issue:2 This study was conducted to explore the potential benefits of using cinnamaldehyde (CIN), resveratrol (RES) separately or in combination on cyadox (CYA)-induced alterations in isolated rabbit erythrocytes. Erythrocytes suspensions were partitioned into 7 groups (5 replicates/group), 1st kept as control treated with phosphate buffered saline (PBS) with dimethyl sulphoxide (DMSO); 2nd group was subjected to CYA (40 μg/ml), 3rd group was incubated with CIN (40 μM), 4th group was subjected to RES (40 μM), 5th group was co-exposed to CYA (40 μg/ml) and CIN (40 μM), 6th group was co exposed to CYA (40 μg/ml) and RES (40 μM), and 7th group was exposed to CYA in combination with both CIN and RES at the same indicated concentrations. The reaction mixtures of different groups were incubated at 37 °C for 3 h with gentle shaking every 15 minutes. Our results revealed that exposure to CYA caused a significant decrease (linear and quadratic) in superoxide dismutase (SOD) and catalase (CAT) activities and the contents of reduced glutathione (GSH) and glutathione transferase (GST). Incubation of erythrocytes with CYA increased GSSG content, GSSG/GSH ratio, malonaldehyde (MDA) and protein carbonyl (PrC) concentrations while it decreased the total protein (TP). CYA also lead to hemolysis and energy depletion of erythrocytes beside activation of caspase cascades, suggesting the pro-oxidant effect CYA that could be implicated in eryptosis. CIN and RES were able to inverse these hazardous effects of CYA. However, CIN was more effective than RES, their combination showed a positive synergistic effect in protecting the cells against oxidative injury caused by CYA.

One-pot construction of sterically challenging and diverse polyarylphenols via transition-metal-free benzannulation and their potent in vitro antioxidant activity. Organic & biomolecular chemistry, 2017, Mar-01, Volume: 15, Issue:9 This paper reports the novel and efficient one-pot synthesis of highly functionalized polyarylphenols from readily available 1,3-diarylpropan-2-ones and chalcones or cinnamaldehyde derivatives via benzannulation under transition-metal-free and aerobic conditions. This benzannulation proceeds through cascade Michael addition/intramolecular aldol/tautomerization/oxidation. This protocol produces various tetra- and tri-aryl substituted phenols in moderate to good yield. The synthesized compounds exhibited potent antioxidant activities compared to the standard BHT.
