A compound containing carboxylate ester and N2S2 ligand bi-functional groups and a manufacturing method thereof are disclosed. The S in the N2S2 ligand of the compound containing carboxylate ester and N2S2 ligand bi-functional groups includes a protective group so as to avoid to be oxidized and easy storage. In a complex reaction, the protective group is automatically released As to the active carboxylate ester, it is for reacting with compounds having amino groups such as amines, amino acids, peptides, or protein etc while the N2S2 ligand is for bonding with technetium or rhenium so as to form neutral complex. The compound containing carboxylate ester and N2S2 ligand bi-functional groups is applied to radiopharmaceuticals such as contrast agents for tissues and target agents.
揭示了一种含有羧酸酯和N2S2配体双功能基团的化合物及其制备方法。所述化合物中N2S2配体中的S包含有保护基团,以避免氧化并便于储存。在复杂反应中,保护基团会自动释放,使活性羧酸酯可以与具有氨基的化合物(如胺、氨基酸、肽或蛋白质等)反应,而N2S2配体则与锝或铼结合,形成中性配合物。含有羧酸酯和N2S2配体双功能基团的化合物应用于放射性药物,如组织对比剂和靶向药物。
