Compounds for site-enhanced delivery of radionuclides |
| abstract |
A dihydropyridine⃡pyridinium salt type of redox, or chemical, delivery system for the site-specific and/or site-enhanced delivery of a radionuclide to the brain. A chelating agent capable of chelating with a radionuclide and having a reactive hydroxyl, carboxyl, amino, amide or imide group is coupled to a carrier moiety comprising a dihydropyridinie⃡pyridinium salt nucleus and then complexed with a radionuclide to provide a new radionuclide pharmaceutial that, in its lipoidal dihydropyridine form, penetrates the blood-brain barrier (`BBB`) and allows increased levels of radionuclide concentration in the brain, particularly since oxidation of the dihydropyridine carrier moiety in vivo to the ionic pyridinium salt retards elimination from the brain while elimination from the general circulation is accelerated. This radionuclide delivery system is well suited for use in scintigraphy and similar radiographic techniques. |
