Description: WUN55267, also known as GPR40/FFAR1 modulator 1, is an agonist and an allosteric modulator for Gq-coupled free fatty acid receptor 1 (GPR40/FFAR1). This molecule was first reported in Proceedings of the National Academy of Sciences of the United States of America (2019), 116(14), 7123-7128. This product has no formal name at the moment. For the convenience of communication, a temporal code name was therefore proposed according to MedKoo Chemical Nomenclature (see web page: https://www.medkoo.com/page/naming).
