neurotransmitter

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].

Vasopressin acetate, a cyclic nonapeptide, is synthesized centrally in the hypothalamus. Vasopressin acetate acts as a neurotransmitter, exerting its action by binding to specific G protein-coupled receptors.

Neurotensin TFA (39379-15-2 free base) is an endogenous 13 amino acid neuropeptide with profound opioid-independent analgesic effects. It behaves as a neurotransmitter in the brain, as a hormone in the gut, and also as a neuromodulator. It is implicated in the pathophysiology of several CNS disorders (including schizophrenia, Parkinson's disease, drug abuse, pain, cancer, inflammation, eating disorders, and central control of blood pressure) due to its association with a wide variety of neurotransmitter systems such as dopaminergic, sertonergic, glutamatergic, GABAergic, and cholinergic systems. It has a role as a human metabolite, a mitogen, a neurotransmitter and a vulnerary.

Biotin-Substance P acts as a neurotransmitter and neuromodulator in the central nervous system. Neurokinin 1 receptor (NK1R) is the endogenous receptor of Biotin-Substance P.

Certain chronic neurologic disorders, such as Parkinson's disease, are caused by an insufficiency of the neurotransmitter dopamine secondary to the degeneration of substantia nigra dopaminergic neurons. N-(α-Linolenoyl) tyrosine (NALT) is a simple α-amide conjugate between the ω-3 essential fatty acid α-linolenate and the amino acid tyrosine. α-Linolenate is an important precursor to docosahexaenoic acid (DHA), a prominent brain polyunsaturated fatty acid, while tyrosine is the metabolic precursor for neuronal dopamine synthesis. NALT was prepared as a method for enhancing central nervous system (CNS) dopamine content by facilitated transport of the tyrosine precursor across the blood-brain barrier. In experimental rat models of dopamine insufficiency, NALT increased CNS dopamine levels and exhibited an activity profile consistent with an anti-Parkinson's therapeutic agent.

Neurokinin A TFA (Substance K TFA), a peptide neurotransmitter of the tachykinin family, functions via the NK-2 receptor and acts as a key mediator in human airway and gastrointestinal tissues [1].

CART(62-76)(human,rat) TFA, a neuropeptide encompassing residues 62-76 of the CART peptide, exhibits neurotransmitter-like properties and modulates the striatal noradrenergic system, as well as the corticostriatal and hypothalamic serotoninergic (5-HT) systems in the rat brain [1].

Biotin-Neurokinin A, a biotinylated form of Neurokinin A (Substance K), functions as a peptide neurotransmitter within the tachykinin family, primarily engaging the NK-2 receptor. It serves as a significant mediator in the physiological processes of human airway and gastrointestinal tissues [1].

[Gly11] Substance P, an analog of Substance P itself, functions as a neuropeptide within the CNS, serving dual roles as both a neurotransmitter and neuromodulator [1].

[His11]Substance P, an analog of Substance P (Substance P), functions as both a neurotransmitter and neuromodulator in the central nervous system (CNS) [1].

[MePhe8,Sar9] Substance P ([MePhe8-MeGly9] Substance P) is a synthetic analog of Substance P, a neuropeptide that functions as both a neurotransmitter and neuromodulator in the central nervous system (CNS).

Vasoactive Intestinal Peptide (VIP) Guinea pig TFA, a trophic and mitogenic factor, promotes growth in cultured whole embryos and acts as a gastrointestinal hormone, while also indicating potential neurotransmitter functions [1] [2].

Endokinin C, a peptide constituent of endokinin, functions as a neurotransmitter or modulator within the pain pathway. Pretreatment with this compound impedes the onset of scratching behavior and thermal hyperalgesia induced by endokinin A B in mice [1].

[Thr28, Nle31]-Cholecystokinin (25-33) is a bioactive peptide analog of Cholecystokinin (CCK) that functions as both a hormone and neurotransmitter in the gastrointestinal and central nervous systems, playing a role in satiation by inhibiting food intake. Compared to native CCK8, this analog displays enhanced stability in acidic environments and resistance to air oxidation, due to the substitution of Methionine with Threonine at position 28 and Norleucine at position 31. Structurally, it features a gamma-turn at Thr4, followed by a Gly5-separated helical region encompassing the C-terminal residues.

Vasopressin (argipressin), a cyclic nine-peptide synthesized by hypothalamic neurons, is one of the hormones involved in peptide prohormone synthesis. Vasopressin is involved in the regulation process of hypothalamic-pituitary-adrenal axis, increasing the amount of solute free water reabsorbed from the renal tubule's colate back into the circulation, narrowing arteries to increase pressure, enhancing the stimulating effect of corticotropin releasing factor to regulate pituitary corticotropin secretion. Vasopressin acts as a neurotransmitter during nerve conduction by binding to specific G-protein-coupled receptors.

beta-MSH, human is an endogenous peptide hormone and neurotransmitter produced by pro-opiomelanocortin (POMC), and is also an agonist of MC4-R (melanocortin 4 receptor).

Substance P acetate is a peptide mainly secreted by neurons and is involved in many biological processes including nociception and inflammation. Substance P acetate is a neuroinflammatory factor that can act as a neurotransmitter and neuromodulator in the central nervous system and can be used to study cardiovascular and neurological diseases.

Neuropeptide S (Mouse) acetate is a bioactive peptide. Neuropeptide S (Mouse) acetate, as a neurotransmitter/neuromodulator of 20 amino acids, can be used for the research of arousal, anxiety, locomotion, feeding behaviors, memory and drug addiction[1].

Mammalian bombesin-like peptide neurotransmitter that is an agonist for the gastrin-releasing peptide receptor (GRPR). GRP has been reported to activate GABAergic interneurons in the amygdala leading to increased GABA release and fear suppression in mice

Dynorphin A is an endogenous opioid peptide and a κ-opioid receptor (KOR) agonist, with some agonistic activity on μ- and δ-opioid receptors. It primarily functions as a neurotransmitter and regulator in the central and peripheral nervous systems, exerting analgesic and mood-regulating effects.

Substance P TFA (Neurokinin P TFA) is a neuropeptide that functions as both a neurotransmitter and neuromodulator in the central nervous system, specifically targeting the neurokinin 1 receptor (NK1-receptor, NK1R).
