AB  - Introduction: Phenols are a large family of natural and synthetic compounds with known antioxidant activity. The aim of this study was to perform in vitro screening of natural and natural-like phenol monomers and their C2-symmetric dimers (hydroxylated biphenyls) in order to identify those representatives whose pharmacophores have the strongest antioxidant and the lowest prooxidant activity. Material and methods: Antioxidative properties of 36 compounds (monomers and their C2-symmetric dimers) were evaluated in vitro. Different (red/ ox) assays were used to measure their total oxidative potential (TOP), their total antioxidative capacity (TAC), the pro-oxidative-antioxidant balance (PAB) and total SH-group content (SHG) in a biologically relevant environment. The Pro-oxidative Score, Antioxidative Score and the Oxy Score were also calculated. Trolox, a water soluble analogue of α-tocopherol, was used as a positive control. Results: In an assay consisting of pooled human serum, 6 of the 36 compounds showed significant antioxidant activity (compounds 6, 7, 12, 13, 26, and 27), whereas 4 showed extremely weak antioxidant activity (compounds 2, 29, 30, and 31). Within the 36 compounds comprising zingerone, dehydrozingerone, aurone, chalcone, and magnolol derivatives, in both monomeric and dimeric forms, the 2 compounds that indicated the highest antioxidant activity were dehydrozingerone derivatives (compounds 6 and 12). Trolox’s activity was found between the strong and weak antioxidant compounds analysed in our study. Conclusions: In this study selected dehydrozingerones were identified as good candidates for in-depth testing of their biological behaviour and for possible precursors for synthesis of novel polyphenolic molecules with potential therapeutic applications.

AB  - A comparative in vitro study of the antioxidant potential of natural phenols (zingerone, curcumin, raspberry ketone, magnolol) and their synthesized derivatives was performed. The antioxidant efficiency was evaluated in blood serum obtained from healthy individuals, by means of spectrophotometry, before and after the addition of pro-oxidant tert-butyl hydroperoxide (TBH). Moreover, the antioxidant effect of an equimolar mixture of curcumin and zingerone was investigated. Interpretation of our results reveals that in the blood serum of healthy individuals curcumin (C1), raspberry ketone (RK1), magnolol (M1) and synthesized derivative of zingerone (Z2) demonstrate remarkable antioxidant effects (p < 0.05). However, in the state of TBH-induced excessive oxidative stress natural magnolol and synthesized derivatives C1, Z1 and RK1 show powerful antioxidant activity and thus can be further investigated to obtain information about their metabolic transformations and their potential influence at the cellular level. Results obtained from measurements in an equimolar mixture of zingerone and curcumin indicate synergism (p < 0.05) between the two compounds. This combination is especially successful due to the fast and efficient neutralization of added pro-oxidant TBH. The commercial availability of turmeric and ginger and their frequent combined use in diet suggest ideas for further broader utilization of the beneficial synergistic effect of their phenolic components.
