Potency (IC50, micromolar) of BAY36-7620 in inhibiting the action of glutamate on the wild-type mGlu1 and various chimeric mGlu receptors. For each receptor, the origin of the ECD (from mGlu1, mGlu2, or mGlu5) and the 7TM [from mGlu1, DmGluA, mGlu2, mGlu5, or mGlu1 and mGlu5 (1/5)] are indicated. Data are means ± S.E.M. of at least three independent experiments performed in triplicate. >100 means that no significant inhibition of the Glu-induced IP formation was detected with 100 μM BAY36-7620.
