General description
A blood-brain barrier permeable and bioavailable chromenone compound that acts as a potent, selective, and reversible antagonist of mGlu7 receptor (IC50 = 3.5 and 2.8 µM for mGlu7a and mGlu7b in CHO cells). Docks within the Venus flytrap domain (VFTD) close to the binding site of L-glutamate and functions as an orthosteric-like antagonist. Reduces DL-2-amino-4-phosphonobutyric acid (DL-AP4)-induced activation of human mGlu7b receptor (IC50 = 2.8 µM), but does not affect DL-AP4-induced activation of [35S]GTPγS binding by mGlu4 and mGlu6. Shown to diminish [35S]GTPγS binding by the human mGlu7/6 chimeric receptor harboring mGlu7 VFTD (IC50 = 2.5 µM). Displays weak binding affinity towards mGlu5 and mGlu8 receptors (IC50 >20 and 33 µM, respectively) and has no effect on GABA-induced activation of [35S]GTPγS binding by GABA-B receptors. Displays antidepressant and anxiolytic-like properties and selectively blocks long-term potentiation (LTP) in the lateral amygdala of wild type (IC50 = 88 nM), but not of mGlu7- deficient mice.
