One embodiment of the invention is a composition that comprises a radioactive
32
P or
33
P phosphine oxide molecule. The said composition is designed to bind to the transient potential receptor-M8 (TRP-M8) receptor of cells. The radioactive
32
P or
33
P phosphine oxide ligand may be used for radioreceptor binding studies and for diagnostic studies of cancerous tissues. The TRP-M8 receptor is selectively expressed in malignant tissues such as prostate cancer cells. Affinity of the
32
P or
33
P phosphine oxide ligand for the TRP-M8 receptor confers selectively and specificity in delivering lethal radiation to the diseased cells.
本发明的一种实施例是一种组合物,其包含一种放射性32P或33P膦氧化物分子。该组合物被设计用于结合细胞的瞬时电位受体-M8(TRP-M8)受体。放射性32P或33P膦氧化物
配体可用于放射性受体结合研究和癌组织诊断研究。TRP-M8受体选择性地表达在恶性组织中,如前列腺癌细胞。32P或33P膦氧化物
配体对TRP-M8受体的亲和力赋予了选择性和特异性,可将致命辐射传递给患病细胞。
