生物活性

TC14012 TFA, a serum-stable derivative of T140, is a selective and peptidomimetic CXCR4 antagonist with an IC50 of 19.3 nM. TC14012 TFA is a potent CXCR7 agonist with an EC50 of 350 nM for recruiting β-arrestin 2 to CXCR7. TC14012 TFA has anti-HIV activity and anti-cancer activity[1][2].

IC50 & Target[1][2]

体外研究
(In Vitro)

TC14012 TFA (1 mM) inhibits more than 95% the infection of the CXCR4-expressing cells by the HXB2 (X4) or 89.6 (dual-tropic) strain whereas TC14012 TFA (1 mM) does not inhibit all the infection of the CCR5-expressing cells by the SF162 (R5) or 89.6 (dualtropic) strain[1].
TC14012 TFA leads to erk 1/2 phosphorylation in U373 cells, which express endogenous CXCR7 but not CXCR4. Upon stimulation with TC14012 TFA, CXCR7 and the CXCR7-Cter4 chimera are able to recruit arrestin, whereas CXCR4 and CXCR4-Cter7 remain silent[2].

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.
