VU6005649 is a CNS penetrant mGlu7/8 receptor agonist with EC50s of 0.65 uM and 2.6 uM for mGlu7 receptor and mGlu8 receptor, respectively.
VU6005649 is a CNS penetrant mGlu7/8 receptor agonist with EC50s of 0.65 uM and 2.6 uM for mGlu7 receptor and mGlu8 receptor, respectively. VU6005649 displays a terminal Kp of 2.43 with total brain levels ~9× above the mGlu7 positive allosteric modulator (PAM) in vitro EC50[1].
When VU6005649 (compound 9f) is dosed at 30 mg/kg IP in 10% Tween 80/H2O (0.75 mg/kg. s.c. amphetamine), no efficacy is observed in this assay. VU6005649 shows modest but significant pro-cognitive effects on associative learning in wild-type mice and the first example of efficacy of an mGlu7/8 positive allosteric modulator (PAM) in this model[1].
