HgX3) were obtained with a complex counterion in the second coordination sphere of copper(II). With C(NO2)4 the intermediate reaction product in non-polar solvents was assumed to be Cu(dtc)·NO2 which dissociates to Cu(dtc)+…NO2− in polar solvents. Similar EPR spectra were obtained with SnEt4 and PbEt4. The reaction of Cu(dtc)2 with CoCl2, AsBr3 and SbCl3 yielded the mixed-ligand complexes of the type Cu(dtc)Xn

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. Further, the present invention relates to methods of making N—S bond-containing prodrugs of pharmaceutical compounds containing one or more N—H bonds whereby sulfur-containing promoieties are attached to the parent compounds to create at least one N—S bond.
