L-CCG-I activates group III metabotropic glutamate receptors in the hippocampal CA3 region.
Specific agonists of metabotropic glutamate receptors (mGluRs) provide powerful tools to discriminate afferent fibers originating from different presynaptic neurons. The group II mGluR agonists L-CCG-I ((2S,1'S,2'S)-2-(2-carboxycyclopropyl)glycine) and DCG-IV ((2S,2'R,3'R)-2-(2',3'-dicarboxy-cyclopropyl)glycine) are commonly used to distinguish between mossy fiber and associational-commissural ...
متن کاملAction of the neurotoxin -N-oxalyl-L- , -diaminopropionic acid on glutamate metabolism of brain mitochondria.
Mammalian neurolathyrism is a progressive and degenerative disease of central nervous system originating from excessive consumption of Lafhyrus seeds, particularly those of L. sativus. Rao et al. [I] have isolated P-N-oxalyl-L-a&diaminopropionic acid (ODAP) from the seeds of L. satiuus and shown this substance to be the neurotoxin [ 1, 21 Characterization of the biochemical effect and cellular ...
متن کاملStructure-function studies on N-oxalyl-diamino-dicarboxylic acids and excitatory amino acid receptors: evidence that beta-L-ODAP is a selective non-NMDA agonist.
Excitatory amino acids and their receptors play an important role in both normal synaptic transmission and excitotoxic-mediated neuronal death. In the present investigation we have prepared a series of glutamate analogs and examined the pharmacological specificity with which they interact with excitatory amino acid receptors. Included within this group of compounds is a potent excitotoxic amino...
متن کاملPositive and negative modulation of group I metabotropic glutamate receptors.
A discriminating pharmacophore model for noncompetitive metabotropic glutamate receptor antagonists of subtype 1 (mGluR1) was developed that facilitated the discovery of moderately active mGluR1 antagonists. One scaffold was selected for the design of several focused libraries where different substitution patterns were introduced. This approach facilitated the discovery of potent mGluR1 antagon...
متن کاملExcitation of cerebellar interneurons by group I metabotropic glutamate receptors.
Cerebellar basket and stellate neurons (BSNs) provide feed-forward inhibition to Purkinje neurons (PNs) and thereby play a principal role in determining the output of the cerebellar cortex. During low-frequency transmission, glutamate released at parallel fiber synapses excites BSNs by binding to AMPA receptors; high-frequency transmission also recruits N-methyl-d-aspartate (NMDA) receptors. We...
