L-Allylglycine is an amino acid derivative that reduces glutamate decarboxylase (GAD) activity by 60% when administered at a dose of 39.8 μmol/g per hour ex vivo in mouse brain preparations. L-Allylglycine (1.2 mmol/kg, i.p.) induces convulsions and decreases GABA concentration throughout the cerebellum, pons, medulla, striatum, cortex, and hippocampus in mice. Chronic administration (3.2 μg/0.5 μl per hour for 13 days) of L-allylglycine in rats increases locomotor activity in an open field test and impairs attention in the 5-choice serial reaction time task (5CSRTT). In vitro, L-allylglycine inhibits GAD only when used at high concentrations (1-80 mM). The more potent in vivo activity can be attributed to metabolic conversion of L-allylglycine to 2-keto-4-pentanoic acid, a more potent convulsant and GAD inhibitor.

trans-Urocanic Acid ((E)-Urocanic acid), a compound predominantly distributed in the hippocampus and prefrontal cortex, is an isomer of cis-UCA, an epidermal UV-protectant, which enhances the stability of tenofovir eplerenomide in long-acting HIV applications. trans-Urocanic acid potently modulates immune trans-urocanic acid effectively modulates immune function, inhibits human natural killer cell activity in vitro, and can be used in Alzheimer's disease research.

Tetrahydroxystilbene-2-O-β-D-glucoside (EH-201) is a low MW inducer of erythropoietin. Tetrahydroxystilbene-2-O-β-D-glucoside induces expression of erythropoietin, PPAR-γ coactivator 1α (PGC-1α) and haemoglobin in astrocytes and PC12 neuronal-like cells. In vivo, Tetrahydroxystilbene-2-O-β-D-glucoside treatment restores memory impairment, as assessed by the passive avoidance test, in SD, Aβ and KA mouse models. In the hippocampus of mice given Tetrahydroxystilbene-2-O-β-D-glucoside in their diet, levels of erythropoietin, PGC-1α and haemoglobin were increased. Treatment with Tetrahydroxystilbene-2-O-β-D-glucoside might be a therapeutic strategy for memory impairment in neurodegenerative disease, physiological ageing or traumatic brain injury.

TP-050 is a chemical probe, which has oral activity and selectively acts on NMDAR. The EC₅₀ of GluN2A and GluN2D are 0.51 μM and 9.6 μM respectively, and it can penetrate the blood-brain barrier. TP-050 can induce long-term potentiation effect (LTP) in hippocampus, thus promoting neuronal signal transmission.

L-803087 is a potent and selective agonist of the growth inhibitor sst4 receptor with a Ki value of 0.7 nM for sst4, demonstrating over 280-fold selectivity compared to other growth inhibitory receptors. L-803087 induces AMPA-mediated synaptic responses in the hippocampus in vitro and increases seizures in alginate-induced seizure-busting mice in vivo.

Bifeprunox is a potent partial agonist of dopamine D2-like and 5-HT1A receptor (pEC50: 6.37 for hippocampus 5-HT1A; pKis: 7.19 and 8.83 for cortex 5-HT1A and striatum D2). It is an antipsychotic for the research of schizophrenia.

ZSET-845 is an enhancer of cognitive which enhances choline acetyltransferase activity in the hippocampus in the rat.

LuAF60097 is a high-affinity S2 receptor ligand that binds allosterically to the S1 site. This compound also acts as a serotonin transporter (SERT) inhibitor, as demonstrated by increased imipramine binding and elevated 5-HT (serotonin) levels in the hippocampus.

Lecozotan (SRA-333) is a potent and selective 5-HT antagonist developed for Alzheimer's disease treatment. This compound significantly increases the release of glutamate and acetylcholine in the hippocampus and dentate gyrus areas upon potassium ion stimulation, exhibiting cognitive enhancement properties.

Additionally, acute administration can improve learning and memory abilities in rats without affecting their anxiety levels or behavior depression.

N-Stearoyltyrosine (N-(1-Oxooctadecyl)-L-tyrosine) is an analog of Anandamide.
