Mechanism of Action

Targets/IC50/Ki
mGlu4
1.1 μM(EC50)
In vitro
VU0364770 is a potent and effective positive allosteric modulator of mGlu4. VU0346770 exhibits a potency of 1.1 ± 0.2 μM at human mGlu4 in the presence of an EC20 concentration of glutamate and shifts the glutamate concentration-response curve 31.4 ± 4.0-fold to the left. VU0364770 exhibits a potency of 290 ± 80 nM at rat mGlu4 and induces an 18.1 ± 1.7-fold left shift of the glutamate concentration-response curve.
In vivo
VU0364770 shows efficacy alone or when administered in combination with l-DOPA or an adenosine 2A (A2A) receptor antagonist preladenant currently in clinical development. When administered alone, VU0364770 exhibits efficacy in reversing haloperidol-induced catalepsy, forelimb asymmetry-induced by unilateral 6-hydroxydopamine (6-OHDA) lesions of the median forebrain bundle, and attentional deficits induced by bilateral 6-OHDA nigrostriatal lesions in rats. In addition, VU0364770 enhances the efficacy of preladenant to reverse haloperidol-induced catalepsy when given in combination. The effects of VU0364770 to reverse forelimb asymmetry are also potentiated when the compound is coadministered with an inactive dose of l-DOPA, suggesting that mGlu4 positive allosteric modulator may provide l-DOPA-sparing activity.
