Biological Activity

In vitro: VU6005649 is a CNS penetrant mGlu7/8 receptor agonist with EC50s of 0.65 μM and 2.6 μM 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.

In vivo: 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.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
