The (2S,4R)- and (2S,4S)-4-hydroxyglutamates activate cloned mGlu(1a), mGlu(2), and mGlu(8a) receptors with different potencies. Best results were obtained with the (2S,4S) isomer being almost as potent as glutamate on mGlu(1a)R and mGlu(8a)R. Data are interpreted on the basis of the
Lennart Bunch et al.
ChemMedChem, 4(11), 1925-1929 (2009-09-05)
Subtype-selective ligands are of great interest to the scientific community, as they provide a tool for investigating the function of one receptor or transporter subtype when functioning in its native environment. Several 4-substituted (S)-glutamate (Glu) analogues were synthesized, and altogether
Sebastien Alaux et al.
Journal of medicinal chemistry, 48(25), 7980-7992 (2005-12-13)
A series of nine L-2,4-syn-4-alkylglutamic acid analogues (1a-i) were synthesized in high yield and high enantiomeric excess (>99% ee) from their corresponding 4-substituted ketoglutaric acids (2a-i), using the enzyme aspartate aminotransferase (AAT) from pig heart or E. coli. The synthesized
