Publication number: 20140248639Abstract: The present invention is based on applicants' discovery, disclosed herein, of agonists for the TAS2R receptors TAS2R1, TAS2R4, TAS2R9, TAS2R13, TAS2R14, TAS2R16, TAS2R44, TAS2R46, and TAS2R60. The assignment of agonists to these receptors makes assays for identifying compounds that modulate bitter taste possible. For example, the present invention provides methods of identifying compounds that inhibit the bitter taste due to these agonists. The present invention also provides methods of identifying compounds that selectively inhibit the bitter taste due to these agonists. The present invention further provides methods of identifying compounds that mimic the bitter taste due these agonists. The present invention also provides methods of identifying compounds that enhance the bitter taste due to these agonists.Type: ApplicationFiled: October 22, 2012Publication date: September 4, 2014Applicants: KRAFT FOODS GROUP BRANDS LLC, CHROMOCELL CORPORATIONInventors: Kambiz Shekdar, Purvi Manoj Shah, Joseph Gunnet, Jane V.
