The present invention provides screening 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 as well as modifiers capable of modulating chemosensory receptors and their ligands.
The reactions of N-benzoyl-N′-(o-cyanoaryl)thioureas with ethyl bromoacetate under alkaline conditions led to the formation of either fused 2-(alkylsulfanyl)-4-aminopyrimidines or 2-(benzoylimino)-3-(o-cyanoaryl)thiazolidin-4-ones. The accurate application of slightly different reaction conditions allowed us to adjust the balance between the formation of the pyrimidine or thiazolidine heterocycles. Atropisomerism in the 3-(o-cyanoaryl)thiazolidin-4-ones was influenced by the size of the o-cyanoaryl ring, which was investigated by means of NMR measurements and theoretical calculations.
