Detection of free radicals in the presence of DMPO (100 mM). Panel A, (a) hydralazine (125 μM) and Cu2+ (25 μM); (b) + SOD (500 U/ml); and (c) + 2′-deoxyadenosine (5 mM). Panel B, Radical adducts obtained from (a) 2′-deoxyguanosine (5 mM), (b) 2′-deoxycytidine (5mM) and (c) thymidine (5 mM) from hydralazine and Cu2+. These studies were carried out at pH 7.4 as described in the Methods section.
