ABSTRACT
Triclosan (TCS) is commonly used worldwide in a range of personal care and sanitizing products. A number of studies have revealed the presence of TCS in human tissues. It has recently been shown that TCS can interact with AhR in mouse neurons and the one of its effects is the stimulation of reactive oxygen species (ROS) production. Reactive oxygen species perform a wide spectrum of functions in neuronal cells, where they are generated as by-products of cellular metabolism. Therefore the aim of the study was to investigate effects of two synthetic naphthoflavones, the beta-naphthoflavone (ßNF) and alpha-naphthoflavone (αNF), well known agonist and antagonist of AhR on TCS-stimulated cytotoxicity, apoptosis and ROS production in mouse primary cortical neurons in vitro cultures. The results showed that both agonist (ßNF) and antagonist (αNF) of AhR enhanced the LDH release and caspase-3 activity stimulated by TCS. Interestingly, both naphthoflavones decreased the TCS-stimulated ROS production, however, they showed no scavenging properties as revealed by ABTSâ¢+ and DPPH⢠methods. What's more, both ßNF as well as αNF inhibited the activity of xanthine oxidase (XO) stimulated by TCS. Thus, we can assume that αNF or ßNF act in a competitive way over TCS and inhibit its effect on antioxidant enzyme activity.
