S 18986 is a selective, orally active, brain-penetrant positive allosteric modulator of AMPA-type receptors that enhances cognition in rodents by inducing the release of noradrenaline and acetylcholine in the rat hippocampus, subsequently improving object-recognition memory.

(S)-4CPG ((S)-4-Carboxyphenylglycine) is a competitive mGlu1 receptor antagonist that attenuates nociceptive hypersensitivity and nociceptive abnormalities associated with sciatic nerve constriction injuries in rats, and may be used in the study of neurological disorders.

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).
