abstract |
The invention describes compositions and kits comprising at least one nitric oxide enhancing group antimicrobial compound, or pharmaceutically acceptable salts thereof, and novel compositions comprising at least one nitric oxide enhancing antimicrobial compound, and, optionally, at least one nitric oxide enhancing compound 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 antimicrobial compounds of the invention are preferably tobramycin, aztreonam, ciprofloxacin and doripenam. The nitric oxide enhancing antimicrobial compounds are substituted with at least one heterocyclic nitric oxide donor group and/or at least one nitroxide group. The nitric oxide enhancing groups are nitroxides and/or heterocyclic nitric oxide donors. The heterocyclic nitric oxide donors are furoxans, sydnonimines, oxatriazole-5-ones and/or oxatriazole-5-imines. In one embodiment the methods of the invention are for the treatment of bacterial infections associated with pulmonary diseases such as cystic fibrosis and for treating Bacillus anthracis infections. |
