5. 9. Exploring Catalytic Tellurium-Based Antioxidants : Synthesis and Evaluation

   Författare :Jia-fei Poon; Lars Engman; John Murphy; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antioxidant; tellurium; selenium; radical-trapping; chain-breaking; ROS; glutathione peroxidase; tocopherol; aromatic amine; oxidative stress;

   Sammanfattning : This thesis is concerned with the synthesis and evaluation of various tellurium-based chain-breaking antioxidants. The purpose is to find novel regenerable compounds with improved radical-trapping capacity.In the first part of this work, we explore the possibilities to incorporate tellurium into tocopherols and aromatic amines.
