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

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.

Crustacean Cardioactive Peptide (CCAP) is a highly conserved modified cyclic nonapeptide with a primary structure of PFCNAFTGC-NH2, a disulfide bridge between Cys3 and Cys9, which acts as a cardiac gas pedal, neuropeptide transmitter, and hormone with cardiac, adipotropic hormone, and metabolic regulatory effects, reproductive system.
