| 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].

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

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. |
