  • Polyiodinated triglyceride analogs as radiologic agents
    Patent number: 5093042
    Abstract: Novel iodinated arylaliphatic triglyceride analogs as radiologic agents are liver and hepatocyte site-specific. The triglyceride backbone structure is preferably 1,3-disubstituted or 1,2,3-trisubstituted with, in some embodiments, a 3-substituted-2,4,6-triiodophenyl aliphatic chain wherein the chain has a structure similar to naturally occurring fatty acids. In another embodiment, a monoiodophenyl aliphatic chain is utilized. Any position remaining on the triglyceride backbone is substituted with a saturated or unsaturated aliphatic hydrocarbon chain of the type found in naturally occurring fatty acids. The triglyceride analogs can be radioiodinated. In a preferred embodiment, a lipid emulsion is provided as the carrier vehicle.
    Type: Grant
    Filed: April 20, 1990
    Date of Patent: March 3, 1992
    Assignee: The University of Michigan
    Inventors: Raymond E. Counsell, Marc A. Longino, Jamey P. Weichert, Susan P. Schwendner

The triglyceride backbone structure is preferably 1,3-disubstituted or 1,2,3-trisubstituted with, in some embodiments, a 3-substituted-2,4,6-triiodophenyl aliphatic chain wherein the chain has a structure similar to naturally occuring fatty acids. In another embodiment, a monoiodophenyl aliphatic chain is utilized. Any position remaining on the triglyceride backbone is substituted with a saturated or unsaturated aliphatic hydrocarbon chain of the type found in naturally occurring fatty acids. The triglyceride analogs can be radioiodinated. In a preferred embodiment, a lipid emulsion is provided as the carrier vehicle.
