title: Reversed effects of DNA on hydride transfer and electron transfer reactions of acridinium and quinolinium ions.
abstract: DNA inhibits hydride transfer from 1-benzyl-1,4-dihydronicotinamide to the 10-methylacridinium ion, whereas DNA accelerates photoinduced electron transfer from the excited state of Ru(bpy)3(2+) to the 1-methylquinolinium ion. The reason of such reversed effects of DNA on the hydride transfer and electron transfer reactions is clarified.
