  • Patent number: 10048274
    Abstract: In one aspect, the present invention relates to a mammalian cell-based high-throughput assay for the profiling and screening of human epithelial sodium channel (hENaC) cloned from a human kidney c-DNA library and is also expressed in other tissues including human taste tissue. The present invention further relates to amphibian oocyte-based medium-throughput electrophysiological assays for identifying human ENaC modulators, preferably ENaC enhancers. Compounds that modulate ENaC function in a cell-based ENaC assay are expected to affect salty taste in humans.

  • Publication number: 20180106801
    Abstract: This invention relates to assays which screen for compounds that modulate taste elicited by the T1R2/T1R3 sweet taste receptor which include a novel counter screen to eliminate false positives. In addition, the invention contemplates assays which screen for compounds that modulate taste elicited by the T1R1/T1R3 umami taste receptor which include a novel counter screen to eliminate false positives. Preferably the assays are conducted in high throughput format thereby enabling the screening of many hundreds of different compounds whereby the counter screen significantly improves assay efficiency. Further, the invention relates to the use of the compounds identified in the subject screening assays to modulate T1R associated taste perception.

  • Patent number: 9244081
    Abstract: This invention relates to improved electrophysiological assays that measure sodium conductance activity of a delta or alpha human epithelial sodium channel (ENaC) expressed in a test cell in the presence and absence of delta hENaC enhancers. The improvement comprises contacting the test cells with an amount of sodium ion, typically from at least 15 mM to 140 mM, for a time sufficient, e.g. for at least 5 minutes to an hour, prior to the test cells being screened against at least one putative enhancer. It has been surprisingly discovered that this sodium pretreatment enhances assay sensitivity, especially assays that use membrane potential or ion sensitive dyes that detect changes in conductance fluorimetrically. These enhancer compounds have potential application in modulating (enhancing) salty taste perception and for treating disorders involving aberrant hENaC function.
