SP-203 is a potent selective mGlu(5) ligand. It was found to have exceptionally high affinity (IC50 = 36 pM) and potency in a phosphoinositol hydrolysis assay (IC50 = 0.714 pM) for mGluR5. Labeled with fluorine-18 it is useful as a PET radioligand for mGluR5 in human subjects. [(18)F]SP-203 (3-fluoro-5-(2-(2-([(18)F]fluoromethyl)-thiazol-4-yl)ethynyl)benzonitrile) is an effective high-affinity and selective radioligand for imaging metabotropic 5 receptors (mGluR5) in human brain with PET.
