Abstract: The present invention relates to compounds that are effective for targeting sites of angiogenesis for diagnostic and therapeutic purposes. The compounds are of the Formula (I) A-(B)n-C, wherein A is a chelator moiety capable of complexing a radionuclide metal or a moiety capable of binding to a halogen; B is a spacer group; C is an angiogenesis targeting molecule; and n is selected from the integers 0 and 1. The invention also relates to a method of imaging sites of angiogenesis and treating patients through the administration of the compounds of the present invention.

Abstract: A peptide-chelator conjugate that is useful for imaging sites of inflammation in humans comprises a metal chelator coupled to a glycopeptide antibiotic. The metal chelator and the glycopeptide are coupled by a linking group. The linking group may be the divalent radical NH--(CH.sub.2).sub.3 --NH. Alternatively the linking group may be .beta.Ala.sub.3 LysGly-OH and the glycopeptide may be coupled to the N.sup..epsilon. of Lys. A method of imaging a site of inflammation is also provided. The method comprises the step of administering a diagnostically effective amount of a composition comprising a glycopeptide-chelator conjugate comprising a metal chelator coupled to a glycopeptide antibiotic. The glycopeptide-chelator conjugate is in a form complexed with a diagnostically useful metal or an oxide or nitride thereof.
