VU6066098 is a blood-brain barrier penetrant, orally active inhibitor of metabotropic glutamate receptor subtype 2 ( mGlu2 ), with IC50 values of 77 nM and 111 nM against human and rat targets, respectively. VU6066098 induces antidepressant-like activity, inhibits psychosis-like hyperlocomotion, enhances recognition memory and associative learning, and reverses cognitive deficits caused by blast-related traumatic brain injury. VU6066098 can be used in research on major depressive disorder, schizophrenia, Alzheimer's disease, and traumatic brain injury [1].
In Vivo, VU6066098 (1-10 mg/kg; p.o.; single dose) exerts rapid antidepressant-like effects in rats with an oral minimum effective dose of 1 mg/kg, showing efficacy comparable to ketamine at 10 mg/kg p.o[1]. VU6066098 (5.6-56.6 mg/kg; p.o.; single dose) exhibits antipsychotic-like activity in rats with an oral minimum effective dose of 30 mg/kg, reversing amphetamine-induced hyperlocomotion in a dose-dependent manner[1]. VU6066098 (1-10 mg/kg; p.o.; single dose) enhances long-term recognition memory in rats with an oral minimum effective dose of 3 mg/kg, producing a robust improvement in recognition index[1]. VU6066098 (0.1-1 mg/kg; p.o.; single dose) enhances associative learning and long-term memory in rats with an oral minimum effective dose of 0.3 mg/kg, increasing percent freezing behavior in contextual fear conditioning[1]. VU6066098 (10 mg/kg; i.p.; daily; 2 days) reverses cognitive deficits in a rat blast-related TBI model when administered at 10 mg/kg i.p. for 2 days, with effects lasting up to 30 days post-dose[1].
In Vitro, VU6066098 potently and selectively inhibits human mGlu2 receptors in an mGlu2/GIRK assay with an IC50 of 77 nM, while showing no significant activity against most other human mGlu receptor subtypes[1]. VU6066098 inhibits human mGlu2 receptor activity in a cAMP assay with an IC50 of 114 nM[1]. VU6066098 potently inhibits rat mGlu2 receptors with an IC50 of 111 nM, while showing no significant activity against most other rat mGlu receptor subtypes[1].
