Utilization of the resolved L-isomer of 2-amino-6-phosphonohexanoic acid (L-AP6) as a selective agonist for a quisqualate-sensitized site in hippocampal CA1 pyramidal neurons.[Pubmed:7953634]

Brain Res. 1994 Jun 27;649(1-2):203-7.

Brief exposure of rat hippocampal slices to quisqualic acid (QUIS) sensitizes neurons to depolarization by the alpha-amino-omega-phosphonate excitatory amino acid (EAA) analogues AP4, AP5 and AP6. These phosphonates interact with a novel QUIS-sensitized site. Whereas L-AP4 and D-AP5 cross-react with other EAA receptors, DL-AP6 has been shown to be relatively selective for the QUIS-sensitized site. This specificity of DL-AP6, in conjunction with the apparent preference of this site for L-isomers, suggested that the hitherto unavailable L-isomer of AP6 would be a potent and specific agonist. We report the resolution of the D- and L-enantiomers of AP6 by fractional crystallization of the L-lysine salt of DL-AP6. We also report the pharmacological responses of kainate/AMPA, NMDA, lateral perforant path L-AP4 receptors and the CA1 QUIS-sensitized site to D- and L-AP6, and compare these responses to the D- and L-isomers of AP3, AP4, AP5 and AP7. The D-isomers of AP4, AP5 and AP6 were 5-, 3- and 14-fold less potent for the QUIS-sensitized site than their respective L-isomers. While L-AP4 and L-AP5 cross-reacted with NMDA and L-AP4 receptors, L-AP6 was found to be highly potent and specific for the QUIS-sensitized site (IC50 = 40 microM). Its IC50 values for kainate/AMPA, NMDA and L-AP4 receptors were > 10, 3 and 0.8 mM, respectively. As with AP4 and AP5, sensitization to L-AP6 was reversed by L-alpha-aminoadipate.

Type 4a metabotropic glutamate receptor: identification of new potent agonists and differentiation from the L-(+)-2-amino-4-phosphonobutanoic acid-sensitive receptor in the lateral perforant pathway in rats.[Pubmed:7623768]

Mol Pharmacol. 1995 Jul;48(1):140-9.

Before the discovery of the metabotropic glutamate receptors (mGluRs), the glutamate analogue L-2-amino-4-phosphonobutanoic acid (L-AP4) was identified as a potent presynaptic inhibitor of evoked synaptic transmission in the lateral perforant pathway in rats. The localization and L-AP4 sensitivity of the mGluR4a subtype of mGluRs were consistent with the hypothesis that this receptor mediates the synaptic depressant effects of L-AP4 in the lateral perforant pathway. In the present study, the pharmacology of mGluR4a expressed in baby hamster kidney 570 cells was characterized and compared with that previously reported for the lateral perforant pathway responses. The endogenous excitatory amino acid L-aspartate was inactive at mGluR4a, whereas L-homocysteic acid was only 5-fold less potent than L-glutamate. These data suggest that L-homocysteic acid may be an endogenous agonist at mGluR4a. Of the 30 L-AP4 analogues examined, several compounds were identified as agonists at mGluR4a. The cyclopropyl-AP4 analogue (Z)-(+/-)-2-amino-2,3-methano-4-phosphonobutanoic acid inhibited forskolin-stimulated cAMP production with an EC50 of 0.58 microM, which is comparable to that of L-AP4 (EC50 = 0.43 microM). Two other cyclic analogues of L-AP4 were approximately 10-fold less potent as agonists at mGluR4a, i.e., (+/-)-1-amino-3-(phosphonomethylene)cyclobutanecarboxylic acid (EC50 = 4.4 microM) and (E)-(+/-)-2-amino-2,3-methano-4-phosphonobutanoic acid (EC50 = 7.9 microM). Comparison of the potencies of the compounds for activation of mGluR4a with their potencies for inhibition of lateral perforant pathway responses demonstrates that some compounds have comparable activities in the two systems, whereas several compounds are at least 10-fold more potent in one of the systems. In addition, although the mGluR antagonist (+)-alpha-methyl-4-carboxyphenylglycine blocked the effects of L-AP4 in the lateral perforant pathway, it did not block the effects of L-AP4 at the cloned receptor. These data provide evidence that mGluR4a does not mediate the effects of L-AP4 in the lateral perforant pathway, they provide new tools to identify the function of these receptors in the mammalian central nervous system, and they indicate that the effects of L-AP4 in the lateral perforant pathway are mediated by a (+)-alpha-methyl-4-carboxyphenylglycine-sensitive receptor.

Synthesis of oxadiazolidinedione derivatives as quisqualic acid analogues and their evaluation at a quisqualate-sensitized site in the rat hippocampus.[Pubmed:7966155]

J Med Chem. 1994 Nov 11;37(23):3939-46.

The ability of quisqualic acid (1) to sensitize neurons to depolarization by omega-phosphono alpha-amino acid analogues of excitatory amino acids is a highly specific phenomenon and is termed the QUIS effect. In an attempt to elucidate the structure-activity relationships for this sensitization, analogues 2-6 of quisqualic acid have been synthesized. Compounds 4, 5, and 6 showed no quisqualate sensitization with respect to L-2-amino-6-phosphonohexanoic acid (L-AP6), while compounds 2 and 3 were 1/10 and 1/1000, respectively, as active as quisqualic acid in sensitizing neurons toward L-AP6.
