Agonist Comments
Indicated affinities were determined by displacement studies of [3H]quisqualate bound on HEK cell membranes expressing a recombinant rat mGlu5. This is the only study describing affinity values for these compounds. More information on agonist potencies determined from functional studies can be obtained from [85]. So far no differences have been reported for the agonist affinities between the rat and the human receptor.

Antagonist Comments
Indicated affinities were determined by displacement studies of [3H]quisqualate bound on HEK cell membranes expressing a recombinant rat mGlu5 (except for LY341495 value determined from functional studies). This is the only study describing affinity values for these compounds.

More information on agonist potencies determined from functional studies can be obtained from [85]. So far no differences have been reported for the antagonist affinities between the rat and the human receptor.

Surprisingly, although LY367385 and AIDA displace Quisqualate binding, no antagonistic activity of these compounds have been observed in functional studies (see [85]). (S)-4C3HPG has been reported to have slight partial agonist activity at this receptor [41].
