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.

242. A method of screening for a candidate of a chemosensory receptor ligand modifier comprising
determining whether a test entity is suitable to interact with a chemosensory receptor via a first interacting site within the Venus flytrap domain of the chemosensory receptor.
-
243. A method of screening for a candidate of a chemosensory receptor ligand modifier comprising
determining whether a test entity is suitable to interact with a chemosensory receptor via a first interacting site within the Venus flytrap domain of the chemosensory receptor, wherein the first interacting site is identified in light of a second interacting site identified based on the interaction between a chemosensory receptor ligand and the chemosensory receptor.
-
244. A method of screening for a candidate of a chemosensory receptor modifier comprising
determining whether a test entity is suitable to interact with a chemosensory receptor via an interacting site within the Venus flytrap domain of the chemosensory receptor, wherein the interacting site includes an interacting residue selected from the group consisting of N143, S144, I167, S40, S144, S165, Y103, D142, P277, K65, R383, D307, E302, D278, P185, T184, T326, E302, V384, A305, I325, I306, D307, E382, I279, I67, V66, V309, S303, T242, F103, Q328, and S168 of a human T1R2 and a combination thereof, wherein a test entity suitable to interact with the interacting site of the chemosensory receptor is indicative of a candidate of a chemosensory receptor modifier.

246. A method of modulating the activity of a chemosensory receptor ligand comprising contacting a chemosensory receptor ligand modifier with a cell containing T1R2 Venus flytrap domain in the presence of a chemosensory receptor ligand, wherein the chemosensory receptor ligand modifier interacts with an interacting site of the chemosensory receptor.
-
