dynorphin a

Endogenous kappa receptor agonist.

Porcine dynorphin A(1-13) acetate (Dynorphin A Porcine Fragment 1-13 acetate) is a potent, endogenous κ opioid receptor agonist and is antinociceptive at physiological concentrations. Exposure to dynorphin A (1-13) causes acute increases in [Ca2+]i in individual neurons similar to increases seen with acute NMDA treatment.

Dynorphin A (1-10), an endogenous opioid neuropeptide, interacts with the κ-opioid receptor by binding to its extracellular loop 2 and inhibits NMDA-activated current, demonstrating an IC50 value of 42.0 μM.

Dynorphin A (1-10) (TFA), an endogenous opioid neuropeptide, interacts with the extracellular loop 2 of the κ-opioid receptor and inhibits NMDA-activated currents with an IC50 of 42.0 μM.

[DAla2] Dynorphin A (1-13), amide (porcine) is a peptide that potentially acts as a κ opioid receptor agonist, used in nervous system research [1].

Dynorphin (1-8) is an opioid octapeptide from the porcine hypothalamus. It comprises the N-terminal eight residues of dynorphin.

Dynorphin A TFA, an endogenous opioid peptide, plays a role in inhibitory neurotransmission within the central nervous system (CNS). It acts as a highly potent kappa opioid receptor (KOR) agonist and also stimulates other opioid receptors, including mu (MOR) and delta (DOR). Furthermore, Dynorphin A TFA has been observed to induce neuronal death, making it a significant subject in neurological disease research [1] [2].

[DPro10] Dynorphin A (1-11), porcine hydrochloride, is an N-alkylated derivative and potent κ-opioid receptor agonist with a K i value of 0.13 nM, possessing analgesic properties [1] [2].

[DPro10] Dynorphin A (1-11), porcine, an N-Alkylated derivative, serves as a potent κ-opioid receptor agonist with a Ki value of 0.13 nM, exhibiting analgesic properties [1] [2].

Dynorphin A (1-10) acetate is an endogenous opioid neuropeptide, binds to extracellular loop 2 of the κ-opioid receptor. Dynorphin A (1-10) also blocks NMDA-activated current with an IC50 of 42.0 μM.

Porcine dynorphin A (1-13), a potent endogenous κ opioid receptor agonist, exhibits antinociceptive properties at physiological concentrations and induces acute increases in [Ca2+]i in neurons, akin to those observed with acute NMDA treatment.

[DAla2, DArg6] Dynorphin A, (1-13) (porcine) (DADAD), a derivative of dynorphin1-13 (DYN) extracted from porcine pituitary, exhibits high potency at peripheral opioid receptors GPI and MVD. Despite the rapid in vivo degradation of DYN, this compound shows increased resistance to enzymatic cleavage, enhancing its stability against peptide-degrading enzymes [1].

E-2078, known chemically as (N-Me-Tyr1,N-Me-Arg7,D-Leu-NHEt8)-Dynorphin A (1-8), is a stable analog of Dynorphin A (1–8) and functions as a kappa opioid receptor (KOR) agonist [1].

Dynorphin A (1-13) amide, an endogenous opioid peptide, counteracts the analgesic effects of morphine [1].

Dynorphin A acetate is an Endogenous kappa receptor agonist.

Dynorphin A (1-10) (TFA), an endogenous opioid neuropeptide, binds in the transmembrane domain of the κ-receptor.

[DAla2] Dynorphin A (1-9) (porcine) is a dynorphin employed in research focused on analgesia, addiction, and depression.

Dynorphin A, amide, porcine is a polypeptide molecule with the sequence YGGFLRRIRPKLKWDNQ-NH2.

Dynorphin B (1-13), a 13 amino acid, is an extraordinarily potent opioid peptide.

Dynorphin (2-17), amide (porcine) is a dynorphin derivative from the opioid peptide class, synthesized from the precursor protein dynorphinogen, and exhibits analgesic properties, playing a pivotal role in regulating pain, addiction, and mood [1].

Dynorphins are a class of opioid peptides that arise from the precursor protein prodynorphin. When prodynorphin is cleaved during processing by proprotein convertase 2 (PC2), multiple active peptides are released: dynorphin A, dynorphin B, and α/β-neo-end

Nociceptin (Orphanin FQ) is a 17-amino-acid polypeptide that is structurally related to the opioid peptide dynorphin A.

LIH383 is a peptide agonist specifically designed to activate the chemokine (C-X-C motif) receptor 7 (CXCR7), which functions both as a chemokine and an opioid peptide scavenger receptor. Demonstrating a high selectivity, LIH383 activates CXCR7 with an effective concentration (EC50) of 0.61 nM, showing significantly lower affinity towards μ-, δ-, and κ-opioid receptors, as well as the nociceptin opioid peptide (NOP) receptor, even at concentrations of 3 µM in β-arrestin recruitment assays. Furthermore, at a concentration of 3 µM, LIH383 effectively inhibits the uptake of opioid peptides by CXCR7, a process normally induced by dynorphin A, a non-selective opioid receptor agonist, in U87-ACKR3 cells.

Dynorphin B-29 (Leumorphin) (pig) is a peptide that exhibits multifaceted receptor interactions within the brain and isolated tissue systems. This compound is utilized in the study of immunoreactions [1].
