The invention describes novel nitrosated and / or nitrosylated compounds of the invention and pharmaceutically acceptable salts thereof, and novel compositions comprising at least one nitrosated and / or nitrosylated compound of the invention, and, optionally, at least one
nitric oxide donor and / or at least one therapeutic agent. The invention also provides novel compositions comprising at least one compound of the invention, and at least one
nitric oxide donor and / or at least one therapeutic agent. The invention also provides novel kits comprising at least one compound of the invention, that is optionally nitrosated and / or nitrosylated, and, optionally, at least one
nitric oxide donor and / or at least one therapeutic agent. The invention also provides methods for (a) treating bacterial infections; (b) treating viral infections; (c) treating fungal infections; and (d) treating lesions. The nitrosated and / or nitrosylated compounds of the invention are preferably nitrosated and / or nitrosylated
antimicrobial compounds, nitrosated and / or nitrosylated
adenosine antagonists, nitrosated and / or nitrosylated LTB4 antagonists, nitrosated and / or nitrosylated mucoregulators and nitrosated and / or nitrosylated
purine agonists. The methods of the invention are preferably for the treatment of bacterial infections associated with pulmonary diseases such as
cystic fibrosis.
