Abstract
The surface binding association between a positively charged polymeric complex of hypocrellin A (HA) with La3+ (La3+-HA) and calf thymus DNA (CT DNA) was confirmed by ESR and laser flash photolysis techniques along with UV-Vis absorption and fluorescence emission spectra. This surface binding, in cooperation with the longer triplet excited state lifetime of La3+-HA, gave rise to a stronger photodamage of CT DNA both in aerobic and anaerobic conditions by La3+-HA compared with HA.
