MNI 137 is a negative allosteric modulator of mGlu2. MNI 137 inhibits glutamate-induced calcium mobilization with IC50s of 8.3 and 12.6 nM for human and rat.

SBC-110736 is a proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitor.

Basimglurant is a potent, selective and orally available modulator of mGlu5 negative allosteric(Kd of 1.1 nM). In competition binding experiments on human recombinant mGlu5, Basimglurant (RG7090) fully displaces [3H]-MPEP with a Ki of 35.6 nM and [3H]-ABP688 with a Ki of 1.4 nM. In HEK293 cells stably expressing human mGlu5, Basimglurant (RG7090) inhibits quisqualate induced Ca2+ mobilization with an IC50 of 7.0 nM and [3H]-inositolphosphate accumulation (IC50 of 5.9 nM).
