| 内容記述タイプ | Abstract | |||||
| 内容記述 | Radical-scavenging reactivities of newly synthesized 7 planar catechin derivatives substituted by an amino acid, which is lysine, arginine, histidine, asparagine acid, glutamic acid, serine, or cysteine, have been examined by the quenching kinetics of galvinoxyl radical in an acetonitrile solution observed by stopped flow technique. Among the derivatives, one bearing arginine moiety showed an approximate 670-fold enhanced radical-scavenging activity than naturally occurring (+)-catechin, which is due to the strong intramolecular hydrogen bonding between the amino acid and catechin moieties. | |||||
