- Small-molecule modulators of TRP-P8 activity
-
Provided are small-molecule Trp-p8 modulators, including Trp-p8 agonists and Trp-p8 antagonists, and compositions comprising small-molecule Trp-p8 agonists as well as methods for identifying and characterizing novel small-molecule Trp-p8 modulators and methods for decreasing viability and/or inhibiting growth of Trp-p8 expressing cells, methods for activating Trp-p8-mediated cation influx, methods for stimulating apoptosis and/or necrosis, and related methods for the treatment of diseases, including cancers such as lung, breast, colon, and/or prostate cancers as well as other diseases, such as benign prostatic hyperplasia, that are associated with Trp-p8 expression.

- Radioligands for the TRP-M8 receptor and methods therewith
-
One embodiment of the invention is a composition that comprises a radioactive [18F], [123I], [125I], or [131I]—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 [18F], [123I], [125I], or [131I]—N-radiohaloaryl-alkylcarboxamide ligand may be used for radioreceptor binding studies, for diagnostic studies, and for radiotherapy of cancerous tissues. Affinity of the [125I] or [131I]—N-radiohaloaryl-alkylcarboxamide ligand for the TRP-M8 receptor confers selectivity and specificity in delivering lethal radiation to the diseased cells.
