γ-Aminobutyric acid (4-Aminobutyric acid) is the predominant inhibitory neurotransmitter in the central nervous system.

In the CNS, Kainic acid is an effective agonist at excitatory amino acid receptor subtypes.

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.

Eudesmin shows antiinflammatory, neuritogenic, anticonvulsant and sedative effects, the mechanism of eudesmin may be related to up-regulation of GABAA and GAD65 expressions, and anti-apoptosis of neuron the in brain.50 microM (+)-eudesmin can induce neurite outgrowth and enhance nerve growth factor (NGF)-mediated neurite outgrowth from PC12 cells by stimulating up-stream MAPK, PKC and PKA pathways.

Cimicifugoside H1 shows the protective function to cerebral neuron during cerebral ischemia.

3'-Methoxypuerarin shows neuron protection activity, it can protect hippocampal neurons against ischemia reperfusion injury by inhibiting apoptosis. 3'-Methoxypuerarin(3'- Methoxy Puerarin) has antioxidant activities, it shows ONOO(-) scavenging activity and weak NO· and O(2)(-) scavenging activities.

1. Acetylcorynoline (O-Acetylcorynoline) has antifungal,anti-inflammatory activity. 2. Acetylcorynoline may be one of the potent immunosuppressive agents through the blockage of dendritic cells maturation and function. 3. Acetylcorynoline is potential as a possible antiparkinsonian drug. (1) Significantly decreases dopaminergic neuron degeneration induced by 6-hydroxydopamine in BZ555 strain; (2) Prevents α-synuclein aggregation; (3) Restores food-sensing behavior, and dopamine levels; (4) Prolongs life-span in 6-hydroxydopamine-treated N2 strain. 4. Acetylcorynoline may exert its effects by decreasing egl-1 expression to suppress apoptosis pathways and by increasing rpn5 expression to enhance the activity of proteasomes.

Dermorphin TFA is a new class of opioids-like peptides

Deserpidine (Harmonyl) is only found in individuals that have used or taken this drug. It is an ester alkaloid drug isolated from Rauwolfia canescens (family Apocynaceae) with antipsychotic and antihypertensive properties that has been used for the control of high blood pressure and for the relief of psychotic behavior.Deserpidine's mechanism of action is through inhibition of the ATP Mg2+ pump responsible for the sequestering of neurotransmitters into storage vesicles located in the presynaptic neuron. Deserpidine is a competitive angiotensin converting enzyme (ACE) inhibitor. Deserpidine also decreases angiotensin II-induced aldosterone secretion by the adrenal cortex.

Myomodulin is a neuropeptide present in molluscs, insects, and gastropods. Within these organisms, myomodulin A specifically occurs in two identified Aplysia neurons: the ARC motor neuron [B16] and the abdominal neuron [L10].
