The present invention relates to nitric oxide releasing prodrugs of known drugs or therapeutic agents which are represented herein as compounds of formula (I) wherein the drugs or therapeutic agents contain one or more functional groups independently selected from a carboxylic acid, an amino, a hydroxyl and a sulfhydryl group. The invention also relates to processes for the preparation of the nitric oxide releasing prodrugs (the compounds of formula (I)), to pharmaceutical compositions containing them and to methods of using the prodrugs.
The invention relates to novel compounds having the general formula (I), and which compounds are useful to treat a disorder or disease characterized by bronchoconstriction, e.g. COPD and asthma.

Microspheres are produced by contacting a solution of a macromolecule or small molecule in a solvent with an antisolvent and a counterion, and chilling the solution. The microspheres are useful for preparing pharmaceuticals, nutraceuticals, cosmetic products and the like of defined dimensions.
time, as a result of using 100 MHz n.m.r. spectroscopy in the product analysis of the oxidation of (−) scopolamine with hydrogen peroxide in ethanol. A similar n.m.r. study was undertaken with atropine and tropine and correlation of chemical shifts with N-configuration in the N-oxides, 3–6, was attempted. N-oxidation of scopolamine, and by analogy of related tropane bases, has taken a preferentially equatorial
