Peroxynitrite is the product of the diffusion-controlled termination reaction between two radicals, nitric oxide and superoxide and is a strong oxidant and nitrating intermediate. Critical biomolecules like proteins, lipids and DNA react with peroxynitrite via direct or radical-mediated mechanisms, resulting in alterations in enzyme activities and signaling pathways. The biological consequences...

Information on drug toxicity is used primarily by three segments of the health care industry: the consumer or patient, healthcare practitioners, and research and development (R&D) scientists in the pharmaceutical industry. The major focus of both consumers and health care practitioners is the provision of suitable information for the safe use of drugs for both individuals and specific patient p...

Mitochondria have long been recognized as the generators of energy for the cell. Like any other power source, however, mitochondria are highly vulnerable to inhibition or uncoupling of the energy harnessing process and run a high risk for catastrophic damage to the cell. The exquisite structural and functional characteristics of mitochondria provide a number of primary targets for xenobiotic-in...
