Superoxide or singlet oxygen: The chemiluminescence of Cypridina luciferin analogues in photodynamic solutions the chemiluminecent measurement of the black and green tea antioxidant capacity and the comparision with their antimicrobial activity

Original language description

Luminol, CLA and MCLA CL were studied in three ROS generating chemical systems in vitro (HRP - H2O2, CuSO4 - H2O2 and NaClO - H2O2 system). Measurements were carried out in phosphate buffer (pH 7.4) at 25°C and 37°C using luminometer Fluoroskan Ascent FL. Superoxide dismutase and sodium azide were used as specific scavenger of superoxide anion radical and quencher of singlet oxygen, respectively. Their effect was compared with that of Trolox (water soluble analogue of vitamin E), which should scavenge all reactive species present in the reaction mixture, and tryptophan. As the photodynamic systems we used e.g. phthalocyanines and chlorophyll a. The declared specifity of Cypridina luciferin analogues chemiluminescence based on superoxide and singlet oxygen and the suitability of this prove is discussed.
