产品介绍

Antagonist G TFA 是有效的后叶加压素 (vasopressin) 的拮抗剂。Antagonist G 也是弱的GRP 和缓激肽的弱拮抗剂。Antagonist G 可诱导 AG-1 的转录，是癌细胞对化疗增敏。

生物活性

Antagonist G TFA is a potentvasopressinantagonist. Antagonist G is also a weak antagonist of GRP and Bradykinin. Antagonist G inducesAP-1transcription and sensitizes cells to chemotherapy^[1]^[2].

体外研究
(In Vitro)

Antagonist G (0-100 μM) induces apoptosis is redox-sensitive and caspase-dependently in SCLC cells^[2].
Antagonist G activates JNK1 in SCLC cells^[2].
Antagonist G is not intrinsically a free radical oxygen donor but stimulates free radical generation specifically within SCLC cells (6.2-fold) and increases the activity of the redox-sensitive transcription factor AP-1 by 61%^[2].

Solvent & Solubility

In Vitro:

H₂O

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 (<0)	1. Try to dissolve the peptide in water first. 2. If water fails, add NH₄OH (<50 μL). 3. If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (>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.
