F. Gasparini et al., (+)-4-phosphonophenylglycine (PPG) a new group III selective metabotropic glutamate receptor agonist, BIOORG MED, 10(11), 2000, pp. 1241-1244
A new synthesis of (R,S)-PPG (4-phosphonophenylglycine) and the separation
of the protected enantiomers leading after deprotection to (+)- and (-)-PPG
are described. Pharmacological characterization at the group III metabotro
pic glutamate receptors hmGluR4a and hmGluR7b revealed (+)-PPG as the activ
e enantiomer. (C) 2000 Elsevier Science Ltd. All rights reserved.
