Chelants and macrocyclic metal complexes thereof, methods of preparing the chelants and macrocyclic metal complexes, and radiopharmaceutical compositions comprising the macrocyclic metal complexes are disclosed. Methods of using the macrocyclic metal complexes as radiopharmaceuticals for the diagnosis of cardiovascular disorders, infectious diseases and cancer are also disclosed. Chelants as bifunctional chelators (BFCs) for the radiolabeling of target-specific biomolecules, such as proteins, peptides, peptidomimetics, non-peptide receptor ligands, enzyme inhibitors, and enzyme substrates are disclosed. Methods of using macrocyclic metal complexes containing the chelant-biomolecule conjugates as target-specific diagnostic radiopharmaceuticals that selectively localize at sites of disease and allow an image to be obtained of the loci using gamma scintigraphy are disclosed. Methods of use of the radiopharmaceuticals as imaging agents for the diagnosis of cardiovascular disorders, such as thromboembolic disease or atherosclerosis, infectious disease and cancer are further disclosed.
揭示了螯合剂和其中的大环金属配合物,以及制备螯合剂和大环金属配合物的方法,以及包括大环金属配合物的放射性药物组合物。还披露了将大环金属配合物用作放射性药物的方法,用于诊断心血管疾病、传染病和癌症。还披露了螯合剂作为双功能螯合剂(BFCs)用于标记靶特异性生物分子(如蛋白质、肽、肽类似物、非肽受体配体、酶抑制剂和酶底物)的方法。揭示了包含螯合剂-生物分子结合物的大环金属配合物的方法,用于靶特异性诊断放射性药物,能够选择性地定位在疾病部位并使用γ闪烁摄影获得图像的部位。进一步披露了将放射性药物用作心血管疾病(如血栓栓塞病或动脉粥样硬化)、传染病和癌症的诊断成像剂的方法。
