摘要
Compounds comprising a 3-pyridinol or 5-pyrimidinol ring carrying an organoseleno- or organotelluro- substituent on the pyridine or pyrimidine ring, exhibit useful antioxidant properties. The compounds may for example be in accordance with the following formula (I) as defined herein. Catalytic chain-breaking and hydroperoxide decomposing antioxidant properties are also disclosed. Furthermore the compounds may be used in combination with a reducing agent. The compounds are useful for the stabilization of man-made and natural materials, or for the prevention or treatment of disorders caused by or involving free radical-mediated or oxidative tissue damage.
