5,5-Dimethyloxazolidine-2,4-dione (Dimethadione) is an anticonvulsant that is the active metabolite of TRIMETHADIONE.

Octopamine hydrochloride ((±)-p-Octopamine hydrochlorid) is a biogenic monoamine structurally associated with noradrenaline. It can serve as a neurohormone, a neurotransmitter, and a neuromodulator in invertebrates.

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

L-DOPA (Levodopa) is an orally active metabolic precursor of the neurotransmitter dopamine. It can cross the blood-brain barrier and be converted into dopamine in the brain. L-DOPA exhibits anti-hyperalgesic effects and holds potential in Parkinson’s disease research, and it can also be used to induce Parkinson’s disease models.

Oxidopamine hydrobromide (6-OHDA hydrobromide) is a widely used neurotoxin and an antagonist of the neurotransmitter dopamine. It selectively destroys dopaminergic neurons, promotes COX-2 activation, induces PGE2 synthesis, and stimulates the secretion of the pro-inflammatory cytokine IL-1β. It is commonly used to establish animal models of Parkinson’s disease (PD).

Dopamine hydrochloride (ASL279) is a natural catecholamine neurotransmitter that mainly acts on dopamine receptors (D1-5 receptors) (EC50=2.7 nM). Dopamine hydrochloride induces VEGFR2 endocytosis through D2 dopamine receptor and has pro-angiogenic activity.

Melitracen hydrochloride (Thymeol hydrochloride) , an antidepressant, is used as potential dopamine D1/2 receptor antagonist to treat depression.

Flibanserin (Girosa) is a serotonergic antidepressant used to treat hypoactive sexual desire disorder. Flibanserin has been associated with a low rate of minor serum aminotransferase elevations during treatment but has not been linked to instances of clinically apparent acute liver injury.

Argireline (Acetyl hexapeptide-3) is a peptide composed of amino acid chains that significantly inhibits Ca2+-dependent neurotransmitter (acetylcholine) release at the neuromuscular junction, exhibiting notable anti-wrinkle and anti-aging activity[1][2][3].

(RS)-AMPA ((±)-AMPA) is a glutamate analog and an agonist of the effective and selective excitatory neurotransmitter L-glutamic acid.

Bicuculline is an alkaloid extracted from Corydalis decumbens, acting as a competitive antagonist of the neurotransmitter GABAA receptor (IC50 = 2 μM). It also blocks Ca2+-activated potassium (SK) channels and inhibits slow afterhyperpolarization (slow AHP). Bicuculline has anticonvulsant effects and is commonly used to establish mouse seizure models.

Dizocilpine Maleate (MK-801 maleate) is a potent, selective, and non-competitive NMDA receptor antagonist with a Kd value of 37.2 nM. It is commonly used in the treatment of various neurodegenerative diseases in which NMDA receptors may be involved, and can also be used to induce schizophrenia models.

Dizocilpine (MK-801) is a selective non-competitive NMDA receptor antagonist with a Kd of 37.2 nM that exhibits anticonvulsant effects. It acts by binding to a site within the NMDA-associated ion channel, blocking the flow of Ca²⁺, and is commonly used to establish schizophrenia models.

Prolylleucine (((Benzyloxy)carbonyl)-L-prolyl-D-leucine) is a dipeptide containing branched-chain amino acids.

L-Glutamic acid is an excitatory amino acid neurotransmitter and a Glutamic acid receptor agonist, including metabolic glutamic acid receptor (mGluR), AMPA receptor, NMDA receptor and KA receptor. L-Glutamic acid has an excitatory effect on the process of DA release from dopaminergic nerve endings. L-Glutamic acid can be used in the research of neurological diseases. L-Glutamic acid acts on ionic and metabolic Glutamic acid receptors.

Tyramine (Uteramine) is an indirect sympathomimetic that occurs naturally in cheese and other foods. Tyramine does not directly activate adrenergic receptors, but it can serve as a substrate for adrenergic uptake systems and MONOAMINE OXIDASE to prolong the actions of adrenergic transmitters. It also provokes transmitter release from adrenergic terminals and may be a neurotransmitter in some invertebrate nervous systems.

Noradrenaline tartrate is an effective adrenergic receptor agonist that activates α1, α2, and β1 receptors. It is a precursor of epinephrine and serves as the principal neurotransmitter of most postganglionic sympathetic fibers and the diffuse projection system in the brain originating from the locus coeruleus, and can be used to establish cardiomyopathy models.

Leucomyosuppressin, isolated from head extracts of the cockroach Leucophaea maderae, inhibits evoked transmitter release at the mealworm neuromuscular junction.

TN-871 is a potassium and calcium channel antagonist. TN-871 modulates transmitter release from preganglionic nerve terminals without changing the postsynaptic sensitivity of the ganglion cells to ACh.

CGP 31358 is a new chemical entity with a novel mechanism of action at the NMDA receptor, and as such may form a tool for understanding the molecular pharmacology of this receptor-channel complex. It binds to a site on the NMDA receptor that is coupled to

Spongosine (2-Methoxy adenosine) is a pivotal intercellular signal transmitter, which has demonstrated a diverse bioactivity profile including anti-inflammatory activity and analgesic and vasodilation properties. Spongosine is a natural product isolated from Marine organisms, and first isolated from the marine sponge Cryptotethia crypta in 1950

Guanethidine sulphate, synthesized in 1959, is thought to lowing blood pressure by interfering with the metabolism of chemical transmitter substances in post-ganglionic sympathetic nerve fibres.

SKF89976A is a potent GABA uptake inhibitor, which is selective for GAT-1 (IC50 values are 0.13, 550, 944 and 7210 μM for hGAT-1, rGAT-2, hGAT-3 and hBGT-1 respectively). SKF89976A inhibits transport current competitively (Ki = 7 μM) and transmitter-gated current non-competitively (Ki = 0.03 nM). It is able to pass the blood-brain barrier after systemic administration and is active in vivo.

SFNGGP-NH2 is a biologically active peptide that interacts with Protease-Activated Receptor 3 (PAR-3), a high-affinity thrombin receptor. Human cutaneous mast cells express PAR-3 mRNA, implicating a role in itch mechanotransduction, with both histamine-dependent and independent pathways reported. While PAR-3 alone does not induce itch, it may potentiate itch when co-expressed with PAR-4, enhancing thrombin's action. This suggests that PAR-3's primary function is not as a signal transmitter across the membrane, but rather as a cofactor necessary for PAR-4 activation.
