  Synthesis of 4-methylcoumarin derivatives containing 4,5-dihydropyrazole moiety to scavenge radicals and to protect DNA

  摘要：

  A series of 4-methylcoumarin derivatives containing 4,5-dihydropyrazole moiety were synthesized and their antioxidant activities were evaluated in AAPH (2,2'-azobis(2-amidinopropane hydrochloride))-induced oxidation of DNA, and in trapping DPPH (2,2'-diphenyl-1-picrylhydrazyl) and ABTS(+center dot) (2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonate) cationic radical), respectively. Among coumarin derivatives, 3a-d and 4a-c exhibited the termination of radical propagation-chains in AAPH-induced oxidation of DNA. The ortho dihydroxyphenyl substitution at 5 position and 1-unsubstitution of the 4,5-dihydroxylpyrazole was found enhancing the antioxidant activities of these coumarin derivatives.

  Coumarin and chalcone are naturally occurring compounds, and coumarin as a functional group was combined with chalcone in this work, aiming to test the inhibitory effects of coumarin-substituted chalcones on the oxidation of DNA and on scavenging radicals. It was found that the antioxidant activity of hydroxyl group attaching to coumarin can be increased by hydroxyl groups attaching to chalcone. The double hydroxyl groups at adjacent position exhibited high abilities to inhibit Cu2+/glutathione-induced oxidation of DNA and to trap 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonate) cationic radical (ABTS.) as well as 2,2'-dipheny1-1-picrylhydrazyl radical (DPPH). Especially, the double hydroxyl groups in chalcone were able to protect DNA against 2,2'-azobis(2-amidinopropanehydrochloride) (AAPH)-induced oxidation significantly. On the other hand, the hydroxyl group attaching to coumarin exhibited high ability to inhibit (OH)-O-center dot-induced oxidation of DNA. Therefore, coumarin-appended chalcones exhibited higher antioxidant effectiveness with only single or double phenolic hydroxyl groups contained. (C) 2014 Elsevier Ltd. All rights reserved.
