describe the design, synthesis, and biological evaluation of novel low-molecular PSMA ligands and conjugates with fluorescent dyes FAM-5, SulfoCy5, and SulfoCy7. In vitro evaluation of synthesized PSMA ligands on the activity of PSMA shows that the addition of aromatic amino acids into a linker structure leads to a significant increase in inhibition. The conjugates of the most potent ligand with FAM-5
前列腺特异性膜抗原(PSMA),也称为谷氨酸羧肽酶II(GCPII),由于其在前列腺癌细胞中的过表达而成为抗肿瘤药物和诊断剂特异性递送的合适靶标。在当前的工作中,我们描述了新型的低分子PSMA配体和缀合物与荧光染料FAM-5,SulfoCy5和SulfoCy7的设计,合成和生物学评估。合成的PSMA配体对PSMA活性的体外评估表明,将芳香族氨基酸添加到接头结构中会导致抑制作用的显着增加。最有效的配体与FAM-5以及SulfoCy5的结合物在体外表现出对表达PSMA的肿瘤细胞的高亲和力。体内具有新型PSMA配体的PSMA-SulfoCy5和PSMA-SulfoCy7偶联物在Balb / c裸鼠的22Rv1异种移植物中的生物分布显示了表达PSMA的肿瘤的良好可视化。而且,缀合物PSMA-SulfoCy7证明不存在任何高达87.9 mg / kg的明确毒性。
