生物活性

Pressinoic Acid is a synthetic hexapeptide with potent corticotrophin-releasing activity. Pressinoic Acid is also an oxytocin inhibitor; it induces maternal behavior.

IC50 Target

Oxytocin[1]
体外研究
(In Vitro)

Pressinoic acid, a synthetic hexapeptide that corresponds to the ring of vasopressin, exhibits corticotrophin-releasing activity in vitro in doses of 3 and 30 ng/mL[1].

Peptide Solubility and Storage Guidelines:

1.;;Calculate the length of the peptide.

2.;;Calculate the overall charge of the entire peptide according to the following table:

; Contents Assign value
Acidic amino acid Asp (D), Glu (E), and the C-terminal -COOH. -1
Basic amino acid Arg (R), Lys (K), His (H), and the N-terminal -NH2 +1
Neutral amino acid Gly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q) 0

3.;;Recommended solution:

Overall charge of peptide Details
Negative (lt;0) 1.;;Try to dissolve the peptide in water first.
2.;;If water fails, add NH4OH (lt;50 μL).
3.;;If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (gt;0) 1.;;Try to dissolve the peptide in water first.
2.;;If water fails, try dissolving the peptide in a 10%-30% acetic acid solution.
3.;;If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO.
Zero (=0) 1.;;Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first.
2.;;For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration.

Cell Assay
[1]

Single halved pituitary glands of female CFE rats weighing 100 to 150 g are preincubated for two hours in Krebs-Ringer-bicarbonate-glucose (2%) medium under 5% CO2 in O2, and then for one hour periods each with 300 ng. lysine vasopressin and the sample of vasopressin ring peptide Pressinoic Acid. The incubations are separated by a one hour ish period. The media from the pituitary incubations are added to rat adrenal quarters superfused for estimation of the steroidogenic response to the corticotrophin released. The steroidogenie effect of the unstimulated release of corticotrophin by the pituitary tissue and the possible steroidogenic effect of the peptide directly on the adrenal tissue are measured together by adding the peptide to the media from pituitary tissue incubated without peptide for one hour[1].
