Therefore, MMP imaging for example with radiolabelled MMP inhibitors (MMPIs) potentially represents a valuable tool for clinical diagnostics using non-invasive single photon emission computed tomography (SPECT) or positron emission tomography (PET) imaging. This work includes the organic chemical syntheses and in vitro evaluation of five iodinated barbiturate based MMPIs and the selection of derivative 9 for radiosyntheses of isotopologues [123I]9 potentially useful for MMP SPECT imaging and [124I]9 for MMP PET imaging.<\/jats:p>","DOI":"10.3390\/ph10020049","type":"journal-article","created":{"date-parts":[[2017,5,30]],"date-time":"2017-05-30T10:26:55Z","timestamp":1496140015000},"page":"49","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Syntheses of Radioiodinated Pyrimidine-2,4,6-Triones as Potential Agents for Non-Invasive Imaging of Matrix Metalloproteinases"],"prefix":"10.3390","volume":"10","author":[{"given":"Hans-J\u00f6rg","family":"Breyholz","sequence":"first","affiliation":[{"name":"Department of Nuclear Medicine, University Hospital M\u00fcnster, Albert-Schweitzer-Campus 1, Building A1, D-48149 M\u00fcnster, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Klaus","family":"Kopka","sequence":"additional","affiliation":[{"name":"Division of Radiopharmaceutical Chemistry, German Cancer Research Center (DKFZ), Im Neuenheimer Feld 280, D-69120 Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Sch\u00e4fers","sequence":"additional","affiliation":[{"name":"European Institute for Molecular Imaging (EIMI), University of M\u00fcnster, Waldeyerstra\u00dfe 15, D-48149 M\u00fcnster, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan","family":"Wagner","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, University Hospital M\u00fcnster, Albert-Schweitzer-Campus 1, Building A1, D-48149 M\u00fcnster, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,5,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"663","DOI":"10.2967\/jnumed.109.065698","article-title":"Matrix-metalloproteinases as imaging targets for inflammatory activity in atherosclerotic plaques","volume":"51","author":"Schober","year":"2010","journal-title":"J.
