The present invention is directed to compounds that bind to glycoprotein IIb/IIIa and can be used for diagnostic imaging, in particular magnetic resonance imaging of thrombi. The disclosed compounds enable the binding to glycoprotein IIb/IIIa receptor combined with an adequate relaxivity.本發明係關於結合至醣蛋白IIb/IIIa且可用於血栓之診斷成像、尤其磁共振成像之化合物。該等所揭示化合物使得結合能至醣蛋白IIb/IIIa受體合併足夠弛緩率(relaxivity)。
