Abstract: The present invention relates to novel modified fatty acid analogs, where a positron or gamma-emitting label is placed at a position on a fatty acid backbone and an organic substituent is substituted at the 2,3; 3,4; 4,5; 5,6 and other sequence positions of a fatty acid backbone. These novel fatty acid analogs are designed to enter the tissues of interest by the same long chain fatty acid carrier mechanism as natural fatty acids, however, functional substituents in the 2,3; 3,4; 4,5; 5,6 and other sequence positions, block the catabolic pathway, thus trapping these analogs in a virtually unmodified form in the tissues of interest.

Abstract: Piperidine or piperazine compounds useful for treating neurodegenerated diseases characterized by the lack of dopamine neurons activity or for imaging the dopamine neurons are provided.

Abstract: A method of diagnosing attention deficient-hyperactivity disorder (ADHD) in a human patient by assessing the level of dopamine transporter in at least one region of the patient's central nervous system, where an elevated level of dopamine transporter in the patient is indicative of ADHD. In embodiments of the invention, assessment of dopamine transporter levels includes assessing binding of a dopamine transporter ligand to the dopamine transporters using PET or SPECT.

Abstract: The invention provides imaging agents comprising a label in association with a plaque specific targeting molecule. Methods for using the imaging agents to diagnose or monitor plaque formation and growth and kits containing the cardiovascular agents or components suitable for production of the imaging agents are also provided.

Abstract: Radiopharmaceutical compounds are disclosed. A tropane compound is linked through the N atom at the 8-position to a chelating ligand capable of complexing technetium or rhenium to produce a neutral labeled complex that selectively binds to the dopamine transporter over the serotonin transporter with a ratio of 10 or more. These compounds can be prepared as separate diastereoisomers as well as a mixture of diastereoisomers. Also disclosed are radiopharmaceutical kits for preparing the labeled radiopharmaceutical compounds.

Abstract: The invention provides targeted constructs comprising a targeting moiety, a nucleic acid, and a payload. The payload can be a detectable label or a therapeutic agent. The nucleic acid can be an antisense molecule that is complementary to RNA present in a target cell. The targeted constructs can be used to introduce the payload into a target cell in vivo or in vitro. Accordingly, the invention can be used for diagnostic purposes and for therapeutic purposes.

Abstract: Novel meta substituted arylalkylamine compounds are disclosed. These compounds can be administered as small molecule drugs to treat diseases or conditions associated with insufficient serotonin mediated nerve transmission (e.g., depression and obesity).

Abstract: Methods for determining lymphocyte distribution and trafficking in a mammal are described. Either a labeled ligand capable of interacting specifically with the lymphocytes of the mammal is administered to the mammal so that the labeled ligand interacts in vivo with the lymphocytes, resulting in labeled lymphocytes, or, the labeled ligand is contacted with the lymphocytes in vitro so that the labeled ligand interacts with the lymphocytes resulting in labeled lymphocytes, and these labeled lymphocytes are administered to the mammal. The distribution or trafficking of the labeled lymphocytes in the mammal is determined by imaging.

Abstract: The invention relates to a method of detecting a site of infection or inflammation, and a method for treating such infection or inflammation, in an individual by administering to the individual a diagnostically or therapeutically effective amount of detectably labeled, therapeutic, or therapeutically-conjugated, chemotactic peptide that accumulates substantially at the infected or inflamed site, said chemotactic peptide having the general structureX--Y--Leu--Phe--?Z!.sub.n --Wwherein:X is an amino protecting group,Y is an amino acid residue,Z is a spacer sequence,n is 0 or 1, andW is a labeling or attachment substituent.

Abstract: Novel biotin amide analogs that are useful for targeting therapeutic and imaging agents to sites of infection and tumors in vivo are disclosed.
