AbstractLaser flash photolysis studies have been carried out to investigate the reactions of ciprofloxacin ( CPX) with 2' deoxyguanosine- 5'-monophosphate ( dGMP), N, N, N', N'- tetramethyl- p- phenylenediamine ( TMPD) and ferulic acid ( FCA) in neutral aqueous solutions, respectively. CPXtriplet state ( (CPX)-C-3 *) can be quenched by TMPD, FCA and dGMP, with rate constants of 1.8 X 10(9), 1.5 X 10(9) and 5.8 X 10(7) dm(3) mol)(-1)s(-1), respectively. TMPD radical cation ( TMPD.+) and FCA radical cation ( FCA(.+)) were observed directly. The formation rate of CPX radical anion ( CPX.+)) was determined to be 1.5 X 10(9) dm (-3) mol(-1)s(-1). Redox reaction of dGMP was investigated through competing reactions using TMPD and FCA as probe. The triplet energy of CPX was determined to be 262 kJ mol(-1). Electron transfer from TMPD, FCA and dGMP to (CPX)-C-3 * was proposed.
