N-Methyl-D-aspartic acid is an amino acid that, as the D-isomer, is the defining agonist for the NMDA (N-Methyl-D-aspartic acid) receptor subtype of glutamate receptors.

Ifenprodil is a selective NMDA receptor (glutamate) antagonist.

24-Hydroxycholesterol (Cholest-5-ene-3beta,24-diol) is an oxysterol compound that is an activator of the n-methyl-d-aspartate receptor (NMDA) and the transcription factor LXR, which has been used in the study of cardiogenesis and pancreatic cancer.

Pregnenolone monosulfate (3β-Hydroxy-5-pregnen-20-one monosulfate) is a potent nootropic steroid that positively regulates NMDA recordings and is utilized in the study of neuroticism and depression.

7-Chlorokynurenic acid (7-chloro-4-hydroxy-2-carboxyquinoline) is an effecitve and selective antagonist of NMDA receptor with IC50 of 0.56 μM for the glycine B coagonist site. 7-Chlorokynurenic acid inhibits the reuptake of glutamate into synaptic vesicles with a Ki of 0.59 μM and shows antinociceptive actions after neuraxial delivery.

Urethane (Ethyl carbamate; Ethylurethane) is a byproduct formed during the fermentation process of various foods. As an ethyl ester of carbamic acid, it has the ability to inhibit the growth of bacteria, sea urchin eggs, protozoa, and plant tissues, and is commonly used for establishing lung cancer models.

Quinolinic acid (QUIN) is an endogenous N-methyl-D-aspartate (NMDA) receptor agonist synthesized from L-tryptophan via the kynurenine pathway.

1-Aminocyclopropane-1-carboxylic acid (ACC) is an intermediate in the synthesis of ethylene, the plant hormone responsible for biological processes ranging from seed germination to organ senescence. It is a small molecule agonist at the glycine modulatory site of the NMDA receptor (EC50 = 0.7-0.9 μM) in the presence of low levels (1 μM) of glutamate and as a competitive antagonist at the glutamate-binding site on NMDA receptors (EC50 = 81.6 nM) with high levels (10 μM) of glutamate.2 This compound has been reported to protect against neuron cell death in vivo models of ischemia by enabling moderate levels of NMDA receptor activation and attenuating any excess NMDA receptor signaling that may lead to neurotoxicity.

Spermidine trihydrochloride (4-Azaoctamethylenediamine trihydrochloride), a natural polyamine, is a novel autophagy inducer and negatively modulates N-methyl-d-aspartate (NMDA).

1-[2,4-Dihydroxy-6-methoxy-3-(3-methyl-2-buten-1-yl)phenyl]-3-(4-hydroxyphenyl)-2-propen-1-one (Xanthohumol) , prenylchacone flavonoid, is a natural product with multi-biofunctions purified from Hops Humulus lupulus,is effective against HIV-1 and might serve as an interesting lead compound. It may represent a novel chemotherapeutic agent for HIV-1 infection.

Quinic acid is an organic acid extracted from the bark of Eucalyptus, Cinchona and other plants in the Asteraceae family.

Kynurenic acid (Quinurenic acid) is an endogenous tryptophan active metabolite, a triple antagonist of NMDA, glutamate, α7 nicotinic acetylcholine receptor, and an agonist of GPR35/CXCR8 with neuroprotective and anticonvulsant properties. It has neuroprotective and anticonvulsant properties and can be used to study neurodegeneration and metabolism-related diseases.

Transtorine (1,4-DIHYDRO-4-OXOQUINOLINE-2-CARBOXYLIC ACID) is a GluR and NMDA inhibitor.
