Abstract-IdB 1016 (Siliphos®) is a new silybin-phospholipid complex which is more bioavailable than the flavonoid silybin itself and displays free radical scavenging and antioxidant properties in liver microsomes. IdB 1016 (Siliphos®) at the concentration which completely prevented MDA formation also protected isolated hepatocytes against toxicity. Similar protection was also obtained in hepatocytes prepared in vivo with IdB 1016 (Siliphos®) while rat supplementation with pure silybin was totally inefficient. These results indicate IdB 1016 (Siliphos®) as being a potentially useful protective agent against free radical-mediated toxic liver injury.
Moreover, it was demonstrated here for the first time that IdB 1016 (Siliphos®) can counteract the hepatotoxic effect of several different compounds acting through oxidative mechanisms, indicating the potential usefulness of the compound as a hepatoprotective agent.
