GSK682753A is a selective and highly potent inverse agonist of the epstein-barr virus-induced receptor 2 ( EBI2 ) with an IC 50 of 53.6 nM.
In Vitro
GSK682753 is a selective and highly potent inverse agonist for murine as well as human EBI2 with inhibition of G protein-dependent signals as well as signals that are probably G protein-independent. In cAMP-response element-binding protein-based reporter and guanosine5'-3-O-(thio)-triphosphate (GTPγS) binding assays, the potency of this compound is 2.6-53.6 nM, and its inhibitory efficacy is 75%. GSK682753A dose-dependently inhibits EBI2 with an IC 50 of 53.6 nM. GSK682753A inhibits ERK phosphorylation, GTPγS binding, and cAMP-response element-binding protein activation with similar potency. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
