    摘要: Described herein are D4 receptor-selective compounds of the formula: ##STR1## wherein R.sup.1 is selected from H and an acid labile protecting group; and R.sup.2 and R.sup.3 are independently selected from H, radioisotopic halo, loweralkoxy and tri(loweralkyl)tin; and salts, solvates or hydrates thereof.Also described is the use of these compounds as pharmaceuticals to treat indications for which a dopamine D4 receptor antagonist is indicated. Radiolabeled compounds are useful particularly to image localization of D4 receptor in the human brain, and can therefore aid in the diagnosis of schizophrenia and other medical conditions in which the D4 receptor is implicated.

    摘要: Herein described are radiolabeled compounds and their precursors useful to image D4 receptors in vivo, of the formula: ##STR1## wherein R is selected from iodo, tri(loweralkyl)tin and a radioisotopically labeled iodide and R.sup.1 is selected from H and alkoxycarbonyl, with the proviso that R is not iodo when R.sup.1 is H. The radiopharmaceutical compounds are useful particularly to image localization of D4 receptor in the human brain, and can therefore aid in the diagnosis of schizophrenia and other medical conditions in which the D4 receptor is implicated.

    摘要: The invention includes methods and compounds for labelling conjugates with metals which comprise the steps of coupling the conjugate to a support surface; introducing a complex-forming metal to the support; and collecting the metal-conjugate complex released from the support. The metal catalyzes cleavage of the conjugate from the support upon complex formation resulting in a solutions substantially free of unlabeled conjugate.

    摘要: Described is a process for labelling ligands with metals comprising the steps of covalently coupling the ligand to a solid support via a metal-cleavable linker; introducing a complex-forming metal to the support; and collecting the metal-ligand complex released from the support. The metal catalyzes cleavage of the ligand from the support upon complex formation resulting in a solution substantially free of unlabelled ligand.

    摘要: 1,10-phenanthroline-2,9-dicarboxylic acid and novel derivatives thereof such as 4,7-diphenyl-1,10-phenanthroline-2,9-dicarboxylic acid and 4,5,9,14-tetraaza-(1,2,3,4)-dibenzanthracene-3,5-dicarboxylic acid can be coupled to proteins through coupling groups to form conjugates which form higly fluorescent chelates in the presence of lanthanide salts. Derivatives of the above acids reactive toward proteins can be readily manufactured by relatively simple synthetic routes, and are useful in fluorescent immunoassay.

    摘要: Compounds useful for high resolution diagnostic imaging incorporate an imaging agent having a chelator that is linked by a metal-cleavable bond to a ligand that has affinity for a site removed from the site of diagnostic interest. Upon labelling, the ligand is cleaved leaving the labelled imaging agent free to localize at the site of diagnostic interest unhindered, while the ligand and any unlabelled imaging agent is sequestered to the removed site. By sequestering unlabelled imaging agent, the labelled imaging agent does not compete to occupy the site of interest, resulting in images of enhanced resolution.
