Compounds that are PSMA ligands, pharmaceutical compositions comprising these compounds, methods for treating and detecting cancers in a subject, methods for identifying cancer cells in a sample are described herein. Prostate-specific membrane antigen (PSMA) is a 120 kDa protein expressed in prostate tissues and was originally identified by reactivity with a monoclonal antibody designated 7EII-C5 (Horoszewicz et al., 1987, Anticancer Res. 7:927-935; U.S. Pat. No. 5,162,504). PSMA is characterized as a type II transmembrane protein sharing sequence identity with the transferrin receptor (Israeli et al., 1994, Cancer Res. 54:1807 -1811).
本文描述了PSMA
配体化合物,包括这些化合物的制药组合物,治疗和检测患者癌症的方法,以及在样本中鉴定癌细胞的方法。前列腺特异性膜抗原(PSMA)是一种在前列腺组织中表达的120 kDa蛋白质,最初通过与单克隆
抗体7EII-C5(Horoszewicz等人,1987,抗癌研究。7:927-935;美国专利号5,162,504)反应而被鉴定出来。PSMA被描述为一种II型跨膜蛋白质,与
转铁蛋白受体共享序列同源性(Israeli等人,1994,癌症研究。54:1807-1811)。
