References on (2R,3S)-Chlorpheg

Differential actions of 3-(4-chlorophenyl) glutamic acid stereoisomers and L-trans-pyrrolidine-2,4-dicarboxylic acid upon L-homocysteic acid- and L-glutamic acid-induced responses from rat spinal motoneurones.[Pubmed:8788956]

Neuropharmacology. 1995 Dec;34(12):1589-95.

The four recently synthesized stereoisomers of 3-(4-chlorophenyl) glutamic acid (chlorpheg) were individually examined for their abilities to potentiate depolarizations of neonatal rat motoneurones evoked by L-homocysteic acid (L-HCA, 10 microM). This property had previously been observed using the racemate and is believed to be mediated by uptake inhibition. Both the (2S,3S)- and (2S,3R)- isomers were selective potentiators of L-HCA- (vs L-Glu) induced depolarizations although the (2S,3S)- isomer was more effective. The (2R,3S)- isomer had a slight but significant depressant action which could be attributed to N-methyl-D-aspartate (NMDA) receptor antagonism. Comparison of the potentiating properties of (2S,3S)- and (2S,3R)-chlorpheg with those of L-trans-pyrrolidine-2,4-dicarboxylic acid (tPDC, a L-Glu uptake inhibitor) upon L-HCA- and L-Glu-evoked responses revealed that both chlorpheg isomers (500 microM each) selectively potentiated responses evoked by L-HCA (10 microM) but had no significant effect upon those evoked by L-Glu (50 microM). On the other hand, use of tPDC at the same concentration significantly enhanced the depolarizations evoked by both amino acids, although its action on L-Glu-evoked responses was greater. It is concluded that (i) the (2S,3S)- isomer and to a lesser extent, the (2S,3R)- isomer of chlorpheg are responsible for the potentiating actions seen with the chlorpheg racemate used in previous studies and (ii) (2R,3S)-Chlorpheg is a weak NMDA antagonist. The apparently selective action of (2S,3S)- and (2S,3R)-chlorpheg upon L-HCA-relative to L-Glu-induced depolarizations supports the existence of multiple excitatory amino acid uptake sites, some of which may yet be unidentified.

Diastereoselective synthesis of all four isomers of 3-(4-chlorophenyl) glutamic acid: identification of the isomers responsible for the potentiation of L-homocysteic acid-evoked depolarizations in neonatal rat motoneurons.[Pubmed:8941386]

J Med Chem. 1996 Nov 22;39(24):4738-43.

All four isomers of 3-(4-chlorophenyl)glutamic acid (5-8) were prepared by diastereoselective synthesis. Addition of (6S)-(+)-bis-lactim ether 15 to cis-4-chlorocinnamate 12 gave a mixture comprising mainly the (2R,3S)- and (2R,3R)-isomers 5 and 6, respectively (in a ratio of 56:40), while addition of (6R)-(-)-bis-lactim ether 16 to 4-chlorocinnamate 12 gave a mixture comprising mainly the (2S,3R)- and (2S,3S)-isomers 8 and 7, respectively (in a ratio of 56:42). The four stereoisomers (5-8) were therefore conveniently prepared by addition of either 3-lithio-(6S)- or -(6R)-bis-lactim ether (15 or 16, respectively) to 4-chlorocinnamate 12 and separation of the resultant mixtures of diastereoisomers (23-26) by flash silica gel chromatography. The absolute configurations of 6 and 7 were confirmed by X-ray crystallography. Both the (2S,3S)- and (2S,3R)-isomers (7 and 8, respectively) at a concentration of 100 microM significantly potentiated depolarizations induced by 10 microM L-homocysteic acid (L-HCA) (% control +/- sem: 130.4 +/- 3.6, n = 20 and 114.5 +/- 2.4, n = 11, respectively) while the (2R,3S)-isomer 5 significantly reduced L-HCA response amplitude (94.2 +/- 1.4, n = 9) and the (2R,3R)-isomer 6 was inactive. Experiments designed to compare the agonist-potentiating actions of 7 and 8 in the neonatal rat spinal cord with L-trans-pyrrolidine-2,4-dicarboxylic acid, the well-known L-Glu uptake inhibitor, provided additional evidence for the selective enhancement of depolarizations due to L-HCA and not those due to L-Glu. This selective action supports the existence of multiple excitatory amino acid uptake sites.
