Description

CTCE-9908 TFA is a potent and selective CXCR4 antagonist. CTCE-9908 TFA induces mitotic catastrophe, cytotoxicity and inhibits migration in CXCR4-expressing ovarian cancer cells[1][2].

IC50 & Target[1]

CXCR4

 

In Vitro

CTCE-9908 TFA (0-300 μg/mL; for 10 d) inhibits migration and growth in CXCR4-expressing in ovarian cancer cell lines (IGROV, TOV21G and SKOV3). CTCE-9908 TFA inhibits ovarian cancer cell migration to CXCL12. CTCE-9908 TFA does not cause apoptosis or cellular senescence, but induces multinucleation, G2-M arrest, and abnormal mitosis in ovarian cancer cells. CTCE-9908 TFA deregulates DNA damage checkpoint proteins and spindle assembly checkpoint proteins at G2-M phases of the cell cycle[1].

In Vivo

CTCE-9908 TFA (25, 50 and 100 mg/kg; s.c.; 5 days per week for 4.5 weeks) alone slows the rate of primary breast tumor growth, with a 45% inhibition of primary tumor growth at 3.5 weeks of treatment with 50 mg/kg in FVB/N TgN (MMTV-PyMT)634 male mice[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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
