  Synthesis of licochalcones and inhibition effects on radical-induced oxidation of DNA

  摘要：

  This study deals with the influence of phenolic hydroxyl groups on the antioxidant capacities of licochalcones. (E)-3-[5-(1,2-Dimethyl-2-propenyl)-4-hydroxy-3-methoxyphenyl]-1-(4-hydroxyphenyl)-2-propen-1-one (HMP), (E)-3-[5-(1,2-dimethyl-2-propenyl)-4-hydroxy-3-methoxyphenyl]-1-(2,4-dihydroxyphenyl)-2-propen-1-one (DHM), and (E)-3-[5-(1,2-dimethyl-2-propenyl)-4-hydroxy-3-methoxyphenyl]-1-(2,4,6-trihydroxyphenyl)-2-propen-1-one (HMT) were synthesized via abnormal Claisen rearrangement and Claisen-Schmidt condensation. The antioxidant capacities were evaluated in hydroxyl radical ((OH)-O-aEuro cent)-, Cu2+/glutathione (GSH)-, and 2,2'-azobis(2-amidinopropane hydrochloride) (AAPH)-induced oxidation of DNA. It was found that only HMP possessed weak ability to inhibit (OH)-O-aEuro cent-induced oxidation of DNA, and DHM and HMT cannot protect DNA against the oxidation. All the licochalcones employed herein can retard Cu2+/GSH-induced oxidation of DNA, the activity followed the order of HMP > DHM > HMT. Hence, more hydroxyl groups did not ameliorate the antioxidant effectiveness in the aforementioned experimental systems. On the other hand, HMT, DHM, and HMP can scavenge 5.61, 2.42, and 1.68 radicals, respectively, when they were applied to protect DNA against AAPH-induced oxidation. This result demonstrated that more hydroxyl groups enhanced the antioxidant capacities of licochalcones in this case. The obtained information was beneficial for designing novel licochalcones.Effects on (OH)-O-aEuro cent-, Cu2+/glutathione-, and AAPH-induced oxidation of DNA.
