  • Patent number: 9247759
    Abstract: The present invention relates to the discovery that specific human taste receptors in the T2R taste receptor family respond to particular bitter compounds present in, e.g., coffee. Also, the invention relates to the discovery of specific compounds and compositions containing that function as bitter taste blockers and the use thereof as bitter taste blockers or flavor modulators in, e.g., coffee and coffee flavored foods, beverages and medicaments. Also, the present invention relates to the discovery of a compound that antagonizes numerous different human T2Rs and the use thereof in assays and as a bitter taste blocker in compositions for ingestion by humans and animals.

  • Patent number: 9181276
    Abstract: The present invention includes methods for identifying modifiers of chemosensory receptors and their ligands, e.g., by determining whether a test entity is suitable to interact with one or more interacting sites within the Venus flytrap domains of the chemosensory receptors, and modifiers capable of modulating chemosensory receptors and their ligands. The present invention also includes modifiers of chemosensory receptors and their ligands having Formula (I), its subgenus, and specific compounds. Furthermore, the present invention includes ingestible compositions comprising the modifiers of chemosensory receptors and their ligands and methods of using the modifiers of chemosensory receptors and their ligands to enhance the sweet taste of an ingestible composition or treat a condition associated with a chemosensory receptor. In addition, the present invention include processes for preparing the modifiers of chemosensory receptors and their ligands.

  • Publication number: 20150223503
    Abstract: The present invention relates to processes and intermediates for the preparation of compounds of formula (I): or a salt or oxide thereof, wherein Alk, M1, M2, R1, R2, R3, R4, R5, R6, R7, and n are as described herein. The present invention also relates to compounds of formula (I) and composition comprising a compound of formula (I). Also disclosed is a method of altering or improving the taste of a composition that includes adding to the composition at least one compound of formula (I), in an amount effective to obtain a modified composition having altered or improved taste relative to an otherwise identical composition lacking said compound.
