We are reporting the synthesis, characterization, and calf thymus DNA binding studies of novel chiral macrocyclic Mn(III) salen complexes S-1, R-1, S-2, and R-2. These chiral complexes showed ability to bind with DNA, where complex S-1 exhibits the highest DNA binding constant 1.20 × 10 6 M-1. All the compounds were screened for superoxide and hydroxyl radical scavenging activities; among them, complex S-1 exhibited significant activity with IC50 1.36 and 2.37 μM, respectively. Further, comet assay was used to evaluate the DNA damage protection in white blood cells against the reactive oxygen species wherein complex S-1 was found effective in protecting the hydroxyl radicals mediated plasmid and white blood cells DNA damage.
