摘要 |
One embodiment of the invention is a composition that comprises a radioactive [<SUP>18</SUP>F], [<SUP>123</SUP>I], [<SUP>125</SUP>I], or [<SUP>131</SUP>I]-N-radiohaloaryl-alkylcarboxamide molecule. The composition binds to the transient receptor potential-M8 (TRP-M8) receptor of cells. The TRP-M8 receptor is selectively expressed in sensory neurons and in malignant tissues such as prostate cancer cells. The [<SUP>18</SUP>F], [<SUP>123</SUP>I], [<SUP>125</SUP>I], or [<SUP>131</SUP>I]-N-radiohaloaryl-alkylcarboxamide ligand may be used for radioreceptor binding studies, for diagnostic studies, and for radiotherapy of cancerous tissues. Affinity of the [<SUP>125</SUP>I] or [<SUP>131</SUP>I]-N-radiohaloaryl-alkylcarboxamide ligand for the TRP-M8 receptor confers selectivity and specificity in delivering lethal radiation to the diseased cells.
