生物活性

Eledoisin Related Peptide is a Substance P analog that excites neurons and triggers behavioral responses. Eledoisin Related Peptide is also a tachykinin receptor ligand.

IC50 Target

Tachykinin receptor[1]

体内研究
(In Vivo)

Eledoisin Related Peptide shares with Substance P (SP) a common N-terminal amino acid sequence and has been shown by to have SP-like activity in the periphery (gut and salivary glands) and the CNS. Eledoisin-related peptide seems to be roughly equipotent with Substance P at identical ejection currents on the single-cell activity of neurons in this nucleus[2]. Both glutamate and substance P (and its analogue, eledoisin-related peptide) have excitatory effects on the activity of respiratory neurons and reflex interneurons[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[2]

Rats[2]

Twenty-two male albino rats (230-260 g) are anesthetized with chloral hydrate (400 mg/kg, i.p.) and prepared for recording. Briefly, a singlebarrel recording pipette (tip 1 μm) is glued alongside a conventional five-barrel micropipette (tip 15-25/μm) then filled with 2 M NaCI saturated with Fast Green (impedance 4-7 M). The distance between the tip of the recording electrode and that of the five-barrel micropipette is 15-25/zm. Fast Green is ejected at the end of the experiment to identify the recording site. One side barrel of the five-barrel micropipette is loaded with 4 M NaCI for automatic current balancing and the others with three of the following solutions: L-epinephrine bitartrate (0. l M, pH 4.0), L-norepinephrine bitartrate (0.1 M, pH 4.0), Substance P (2.75 mM), physalaemin (2.6 mM), substance P 4-11 octapeptide (3.1 mM), eledoisin-related peptide (20 mM), neurotensin, bradykinin triacetate (15 mM), met-enkephalin (6.5 mM), TRH (48 mM). Spontaneously active cells are recorded in the locus coeruleus or in the nearby mesencephalic nucleus of the fifth nerve whose cells are easily identified by their increased activity upon manipulation of the jaw[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

生物活性

Eledoisin (Eledone peptide) is a specific agonist of NK2 and NK3 receptors.

IC50 Target

NK2 and NK3 receptors[1].

体外研究
(In Vitro)

Eledoisin (Eledone peptide) increases the value recorded under basal conditions by 24.5±3.7%; this stimulation is significantly (P<0.01) lowered to 13.1±1.9% by the simultaneous presence of CP99994. The same protocol is also used to characterize the sensitivity of Eledoisin stimulation to 0.1 μM SR48968 or 0.1 μM SB222200. SR48968 significantly (P < 0.01) lower the stimulation by Eledoisin, while SB222200 has no effect. Eledoisin stimulation is reduced by CP99994 and SR48968, NK1 and NK2 antagonists, respectively[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

Eledoisin (Eledone peptide; 0.1-1 nmol/kg) injected into rats produces a biphasic cardiovascular response that consists of an initial fall of systemic blood pressure (8-15 mm Hg) followed by a rise (20-22 mm Hg). Intracerebroventricular injection of Eledoisin produces an enhancement of grooming and scratching behavior in mice[2].
