Publication number: 20030119814Abstract: The present invention relates to novel prodrugs of pharmaceutical compounds containing one or more N—H bonds. More specifically, the present embodiment of the invention relates to prodrugs wherein sulfur-containing promoieties are attached to pharmaceutical compounds which contain one or more N—H bonds to produce prodrugs containing at least one N—S bond. These N—S bond-containing prodrugs could have optimized stability, solubility, cell membrane permeability, pharmacokinetic properties and other pharmaceutical properties over the pharmaceutical compounds from which they are formed, depending upon the nature of the promoiety. Reversion of the prodrug to the parent pharmaceutical compound occurs by the reaction of the prodrugs with thiol molecules such as cysteine, glutathione or any other thiol containing molecule.Type: ApplicationFiled: October 16, 2002Publication date: June 26, 2003Applicant: The University of KansasInventors: Victor R.
