  • Patent number: 5186923
    Abstract: The invention relates to compositions that comprise (1) lipophilic cationic organometallic complexes, particularly hexakis(2-methoxyisobutylisonitrile)technetium(I) complex, and (2) an agent that decreases the intramembrane potential of a living cell. Agents which decrease the intramembrane potential of a living cell include the lipophilic anions, especially tetraphenylborate anion. The invention also relates to methods in which the compositions are administered in vivo and in vitro when it is desirable to obtain enhanced cellular accumulation of lipophilic cationic organometallic complexes. The compositions and methods are useful for diagnosis and treatment, particularly in vivo tissue imaging.

  • Patent number: RE34579
    Abstract: The monamine oxidase inhibitor drug L-deprenyl (phenylisopropyl methyl propynyl amine) is safely and conveniently used for the treatment of mental depression in a formulation applied to the skin of the patient. In this way the danger of side reaction due to the consumption of foods containing tyramine (the cheese effect) is minimized. Unlike other monamine oxidase drugs, such as Parnate, L-deprenyl does not cause skin irritation when used in this way.
