The invention provides novel amino acid compounds of use in detecting and evaluating brain and body tumors. These compounds combine the advantageous properties of α-aminoisobutyric acid (AIB) analogs namely, their rapid uptake and prolonged retention in tumors with the properties of halogen substituents, including certain useful halogen isotopes such as fluorine-18, iodine-123, iodine-124, iodine-125, iodine-131, bromine-75, bromine-76, bromine-77, bromine-82, astatine-210, astatine-211, and other astatine isotopes. In addition the compounds can be labeled with technetium and rhenium isotopes using known chelation complexes. The amino acid compounds disclosed herein have a high specificity for target sites when administered to a subject in vivo. The labeled amino acid compounds are useful as imaging agents in detecting and/or monitoring tumors in a subject by Positron Emission Tomography (PET) and Single Photon Emission Computer Tomography (SPECT).
本发明提供了新型氨基酸化合物,用于检测和评估大脑和身体肿瘤。这些化合物结合了α-氨基异丁酸(AIB)类似物的优越性能,即它们在肿瘤中的快速摄取和长时间保留,以及卤素取代基的性质,包括某些有用的卤素同位素,如氟-18,碘-123,碘-124,碘-125,碘-131,溴-75,溴-76,溴-77,溴-82,砹-210,砹-211和其他砹同位素。此外,这些化合物可以使用已知的螯合配合物标记为锝和铼同位素。在体内给予受试者时,本文所披露的氨基酸化合物具有高度特异性的靶向位点。标记的氨基酸化合物可用作成像剂,通过正电子发射断层扫描(PET)和单光子发射计算机断层扫描(SPECT)检测和/或监测受试者的肿瘤。
