Radical scavenging and chemical repair of rutin observed by pulse radiolysis: as a basis for radiation protection

Pulse radiolysis was conducted to investigate: several fundamental reactions of a natural flavonoid, rutin, and its glycosylated form (αG-rutin) as a basis for their radiation protection properties; the reactions with •OH (radical scavenging) and dGMP radical, dGMP• (chemical repair), which was used as a model of initial and not yet stabilised damage on DNA. Three absorption peaks were commonly seen in the reactions of the flavonoids with •OH,...
