VU6053371
VU6053371 (BI03738809) is a first-in-class (FIC), selective, orally active, and brain-penetrant metabotropic glutamate receptor subtype 3 (mGlu3) positive allosteric modulator (PAM) with EC50s of 103 nM and 112 nM for human and rat mGlu3. VU6053371 exhibits selectivity for mGlu3 over other mGlu receptor subtypes. VU6053371 exhibits pro-cognitive effects in mouse models. VU6053371 can be used in research schizophrenia, Alzheimer’ s disease and other forms of dementia and cognitive impairment.

mGluR3 103 nM (EC50, human) |
mGluR3 112 nM (EC50, rat) |
VU6053371 (compound 13I) is an equipotent mGlu3 PAM for both human (EC50 = 113 nM, 61% Glu Max) and rat (EC50 = 112 nM, 58% Glu Max) and, importantly, inactive (EC50 > 30 μM) for both human and rat mGlu2[1].
VU6053371 is metabolized in mouse, rat, minipig, dog, monkey, and human hepatocytes, with the oxidation product M402A being the most abundant metabolite, whereas the glutathione conjugate M562 is not represented in any species tested[1].
VU6053371 displays a good CYP450 profile (IC50s: 3A4 (>30 μM), 2D6 (>30 μM), 2C9 (16 μM), 1A2 (26 μM)), even against 1A2[1].
VU6053371 shows no time-dependent CYP450 inhibition at 3A4, is negative in the mini-AMES (with and without S9), and exhibits no CV/QT concern in a functional EP hERG assay (IC50 > 30 μM)[1].
VU6053371 (10 μM 1 h) leeds to the identification of a GSH conjugate (M691) and forms 5.9% of this adduct after incubation in fortified microsomes with human liver cytosol and GSH[1].

VU6053371 (1-10 mg/kg; p.o.) affords a robust PK/PD relationship for efficacy in the NOR paradigm when unbound brain exposures are at or above the rat mGlu3 PAM EC50[1].
VU6053371 (100-300mg/kg; p.o.; twice a day; 9 days) exhibits an unfavorable toxicological profile in rats[1].

Dosage:1 mg/kg, 3 mg/kg, 10 mg/kg
-
Administration:p.o.;single dose
-
Result:Dose-dependently enhanced recognition memory in rats with a minimum effective dose (MED) of 3 mg/kg PO and a near maximum response at 10 mg/kg PO.
-
Animal Model:Male Sprague-Dawley rats (PO 0.5% natrosol/0.015% Tween 80 in water, 30 min) [1].
