Abstract: The present disclosure generally relates to various formulations and uses of N-(7-acetyl-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-2-(4-acetylpiperazin-1-yl) acetamide (TM1), or any comestibly acceptable salts thereof. In some aspects, the disclosure provides compositions that include TM1, or a comestibly acceptable salt thereof. In some embodiments, the compositions are ingestible compositions, including, but not limited to, packaged food and beverage products. In some other aspects, the disclosure provides uses of TM1, or a comestibly acceptable salt thereof, and related methods for reducing a bitter taste of an ingestible composition, such as an ingestible composition for use in a food, beverage, oral care, nutraceutical, or pharmaceutical product.

Abstract: The present disclosure generally relates to the expression of T1R1+3 taste receptors in eukaryotic cells, such as U2OS cells. The disclosure also relates to the expression of a chimeric T1R3 taste receptor subunit to enable the T1R1 taste receptor subunit to achieve a higher level of sensitivity to umami compounds. Also disclosed are methods of expressing T1R1+3 taste receptors in such cells, and methods of screening for substances that modulate T1R1+3 receptor sensing, and which, therefore, may be useful as modulators of umami taste.

Abstract: The present disclosure generally provides compounds that antagonize certain T2R taste receptors, including related uses, methods, and compositions for the reduction of bitter taste and/or the enhancement of sweet taste. In certain aspects, the disclosure provides flavored articles or flavored compositions comprising such compounds, as well as uses of such compounds to reduce the bitter taste and/or enhance the sweet taste of such flavored articles or flavored compositions.

Abstract: Disclosed herein are 5-Substituted 4-amino-1H-benzo[c][1,2,6]thiadiazine 2,2-dioxide compounds useful as sweet flavor modifiers. Also disclosed herein are ingestible compositions that include one or more of these compounds in combination with a natural or artificial sweetener.

Abstract: The present disclosure generally provides methods for identifying compounds that enhance kokumi taste, and related uses. In some particular aspects, the disclosure provides methods of identifying compounds that enhance kokumi taste by determining whether the compounds modulate the T1R1/T1R3 taste receptor. In some other aspects, the disclosure provides uses of such identified compounds to enhance the kokumi taste of an ingestible composition. In some further aspects, the disclosure provides flavored products, such as food or beverage products, that incorporate such ingestible compositions, and which thereby impart or enhance an umami taste in a flavored article. In some other aspects, the disclosure provides ingestible compositions that contain compounds known to impart or enhance umami taste, such as glutamates, aspartates, and purinic ribonucleotides, such as inosine monophosphate (IMP) and guanosine monophosphate (GMP).

Abstract: The present disclosure generally provides methods for imparting or enhancing an umami taste of a flavored article by introducing a compound that modulates a transmembrane (TM) region of a T1R taste receptor, such as the TM region of a T1r1 taste receptor. In some other aspects, the disclosure provides methods of identifying compounds that modulate a transmembrane (TM) region of a T1R taste receptor, and which thereby imparts or enhances an umami taste in a flavored article. In some other aspects, the disclosure provides compounds that modulate a transmembrane (TM) region of a T1R taste receptor, and their use in food or beverage products, in some cases, in combination with other compounds known to impart or enhance umami taste, such as glutamates, aspartates, and purinic ribonucleotides, such as inosine monophosphate (IMP) and guanosine monophosphate (GMP).

Abstract: The present disclosure relates generally to methods and materials for the identification of compounds that modulate (e.g., enhance, agonize, or antagonize) G protein-coupled receptor (GPCRs), such as those involved in taste. Examples of such GPCR include the TAS1R proteins and the TAS2R proteins that are involved in sensing sweet taste. In certain aspects, the disclosure provides cell-based and label-free assays that use highly sensitive biosensors to detect candidate taste modulator compounds by their alteration of GPCR activity. In some embodiments, such cell-based and label-free assays may be used to detect changes in cell mass distribution, cell adhesion, or cell morphology, resulting from contact with a candidate taste modulator compound. In some embodiments, such assays detect GPCR activation with greatly improved sensitivity compared to conventional assay methods.
