摘要:
Anchimeric chelates are disclosed which are capable of rapidly forming stable chelates with radionuclide metals at or below physiological temperature. Bifunctional anchimeric chelates having these same properties are also disclosed which are useful for radiolabeling target specific molecules such as monoclonal antibodies and fragments thereof.
摘要:
The present invention relates to novel prodrugs of pharmaceutical compounds containing one or more NnullH 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 NnullH bonds to produce prodrugs containing at least one NnullS bond. These NnullS 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 NnullS bond-containing prodrugs of pharmaceutical compounds containing one or more NnullH bonds whereby sulfur-containing promoieties are attached to the parent compounds to create at least one NnullS bond.
