    摘要: A biotinylated cobalamin, formed from a vitamin B.sub.12 molecule coupled to a biotin molecule, is disclosed. In a preferred embodiment, the vitamin B.sub.12 molecule is cyanocobalamin. The biotin molecule can also be coupled to a rerouting moiety, optionally through a biotin binding protein such as avidin or streptavidin. The biotinylated cobalamin binds to a cell surface receptor, is invaginated, and once internalized affects the receptor trafficking pathway.

    摘要: Highly iodinated borane and carborane cage molecules, having from 60% to 90% w/w iodine, are disclosed as new and useful X-ray contrast media when combined with a pharmaceutically acceptable carrier. The inclusion of appropriate functional group substituents, such as hydrophilic moieties, increases solubility and lowers toxicity.

    摘要: Haloaryl compounds are lithiated and thereafter metalated with one of the following organometallic groups: Sn(n--Bu).sub.3 or SnMe.sub.3. The resulting aryltin compound can be transmetalated in site-specific reaction with one of the following organometallic groups: HgX, Hg(OAc).sub.2, BX.sub.3, or BZ.sub.2, wherein X is Cl, Br, or I, and Z is alkyl or alkoxy. The metalated compounds are subsequently radiohalogenated via a demetalation reaction. A functional group suitable for conjugation to protein can be added subsequent or preferably prior to the radiohalogenation.Also compounds of the formula: R.sub.1 --Ar--R.sub.2, wherein R.sub.1 is either a radiohalogen or any one of the organometallic groups stated above, Ar is aromatic or heteroaromatic ring, and R.sub.2 is a short-chain substituent that does not activate the aromatic ring and that bears a functional group, or a precursor thereof, suitable for conjugation to protein under conditions that preserve the biological activity of the protein.The radiohalogenated small molecules are conjugated to proteins such as monoclonal antibodies for use in diagnosis and therapy.
