Endogenous reactive intermediates including photoexcited states of tissue chromophores, reactive oxygen species (ROS), reactive carbonyl species (RCS), transition metal ions, and Schiff bases have been implicated in the initiation and progression of diverse human pathologies including tumorigenesis, atherosclerosis, diabetes, and neurodegenerative disease. In contrast to structure-based approaches that target macromolecules by selective ligands, reactivity-based drug discovery uses chemical reagents as therapeutics that target reactive chemical species involved in human pathology. Reactivity-based design of prototype agents that effectively antagonize, modulate, and potentially even reverse the chemistry underlying tissue damage from oxidative and carbonyl stress therefore holds great promise in delivering significant therapeutic benefit. Apart from its established role as an essential cofactor for numerous enzymes, a large body of evidence suggests that B6-vitamers contain reactive pharmacophores-that mediate therapeutically useful non-vitamin drug actions as Potent antioxidants, metal chelators carbonyl scavengers, Schiff base forming agents, and photosensitizers. Based on the fascinating chemical versatility of B6-derived pharmacophores. B6-vitamers are therefore promising lead compounds for reactivity-based drug design.
