Abstract: The invention provides an assay system for detecting a molecule that interacts with a membrane channel, the assay system including cell membranes including one or more membrane channels; support bodies including scintillant and a coupling agent that associates with the cell membrane; a ligand that is selected to bind the membrane channel, the ligand including a scintillant-activating label. According to the invention, association of the support bodies with the cell membrane and binding of the ligand to the membrane channel results in emission from the scintillant of the support bodies, and, in the presence of a test molecule that interacts with the membrane channel, the emission from the scintillant of the support bodies changes. Methods of identifying a molecule that interacts with a cell membrane channel are also described.

Abstract: This invention is directed to a method for preventing or treating neuropathic pain and cluster and migraine headache-associated pain comprising administering to a subject in need thereof a therapeutically effective amount of a compound of Formula (I): wherein phenyl is substituted at X with one to five halogen atoms independently selected from the group consisting of fluorine, chlorine, bromine and iodine; and; R1, R2, R3 and R4 are independently selected from the group consisting of hydrogen and C1-C4 alkyl; wherein C1-C4 alkyl is optionally substituted with phenyl (wherein phenyl is optionally substituted with substituents independently selected from the group consisting of hydrogen, halogen, C1-C4 alkyl, C1-C4 alkoxy, amino, nitro and cyano).

Abstract: The present invention describes an assay in which pH alters RTX affinity to VR1 receptors. The RTX affinity was increased with increasing pH from 4.1 to 8.6. Both the RTX affinity and apparent number of RTX binding sites were decreased with increasing pH from 8.6 to 10.6. The high pH may be causing the cell membranes to denature. These pH conditions (pH 8.0 to pH 9.0) provide a high signal to noise ratio, give a more robust assay and require use of less experimental materials.
