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.
