    摘要: Iodinated clonidine derivatives useful, inter alia, as a probe for identification and characterization of .alpha..sub.2 -adrenergic receptor sites and as tracers for imaging techniques such as positron emission tomography or computer assisted tomography. Binding competition studies have indicated that p-iodoclonidine, for example, is a particularly efficacious binder for .alpha..sub.2 -adrenergic sites.

    摘要: 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.

    摘要: A surface-modified lipoprotein-like oil-in-water emulsion useful as a blood-pool selective delivery vehicle for lipophilic imaging agents or lipophilic derivatives of water-soluble imaging agents. The blood-pool selective delivery vehicle remains in the blood for several hours, shows very little early hepatic sequestration, and is cleared from the blood within 24 hours. The mean diameter of the oil phase is less than 150 nm which minimizes sequestration by the reticuloendothelial system. The surface of the oil phase is modified with a polyethyl glycol-modified phospholipid to prevent normal interactions with the receptor sites of the hepatocytes. In radiographic imaging, radioactive or stable, synthetic or semi-synthetic polyhalogenated triglycerides, such as 2-oleoylglycerol-1,3-bis[7-(3-amino-2,4,6-triiodophenyl)heptanoate], or lipid soluble derivatives of traditional water-soluble contrast agents, such as aliphatic esters of iopanoic, diatrizoic, and acetrizoic acid, may be incorporated into the lipophilic core of a lipoprotein-like emulsion particle.

The lipophilic core is surrounded by a phospholipid membrane comprising cholesterol and apolipoproteins. For hepatocyte-selective delivery, the emulsion is chylomicron remnant-like by being in a size range of 50 to 200 nm as measured by number weighting analysis with a narrow size distribution (
