Aminoethyl nitrate – the novel super nitrate? [PDF]

British Journal of Pharmacology, 2009
Long‐term use of most organic nitrates is limited by development of tolerance, induction of oxidative stress and endothelial dysfunction. In this issue of the BJP, Schuhmacher et al. characterized a novel class of organic nitrates with amino moieties (aminoalkyl nitrates).
