Patent number: 7875452Abstract: There exists a need in the art for high throughput screening assays that can identify compounds that specifically modulate the activity of fast-acting ion channels, such as TRPM5. Current methods, especially electrophysiological, suffer from a lack of sensitivity, rapid signal loss, low throughput, and are labor intensive. The claimed methods and compositions provide electrophysiology methods that allow prolonged sample testing and fluorescent assays with an optical readout that gives rapid readout of the results, has a high signal to noise background ratio, are easy to use, can be modified for automation and miniaturization, and provide verification that a compound specifically modulates TRPM5.Type: GrantFiled: September 30, 2008Date of Patent: January 25, 2011Assignee: Redpoint Bio CorporationInventors: Robert W. Bryant, S. Paul Lee, Rok Cerne, M. N. Tulu Buber, Ivona Bakaj, Roy Kyle Palmer

Publication number: 20100248987Abstract: The invention relates an assay useful for screening and identifying compounds as modulators of lower alkyl phenol activation of TRPA1. Thymol, a lower alkyl phenol anti-infective and the active ingredient in, e.g., mouthwashes, is stringent and has an objectionable burning taste sensation. Thymol activates the transient receptor potential like ion channel TRPA1. The assay described and claimed herein involves measurement of activation of TRPA1 and enables the screening of compounds that inhibit lower alkyl phenol, or thymol activation of TRPA1. Inhibitors of thymol activation of TRPA1 can be used to prevent the objectionable taste of thymol in medical uses where taste limits acceptance.Type: ApplicationFiled: February 4, 2010Publication date: September 30, 2010Applicant: Redpoint Bio CorporationInventors: Seunghun Paul Lee, Qifeng Yang, Robert W. Bryant, Tulu Buber
