T140 analogs as CXCR4 antagonists identified as anti‐metastatic agents in the treatment of breast cancer
Open accessAbstract
A chemokine receptor, CXCR4, and its endogenous ligand, stromal cell‐derived factor‐1 (SDF‐1), have been recognized to be involved in the metastasis of several types of cancers. T140 analogs are peptidic CXCR4 antagonists composed of 14 amino acid residues that were previously developed as anti‐HIV agents having inhibitory activity against HIV‐entry through its co‐receptor, CXCR4. Herein, we report that these compounds effectively inhibited SDF‐1‐induced migration of human breast cancer cells (MDA‐MB‐231), human leukemia T cells (Sup‐T1) and human umbilical vein endothelial cells at concentrations of 10–100 nM in vitro. Furthermore, slow release administration by subcutaneous injection using an Alzet osmotic pump of a potent and bio‐stable T140 analog, 4F‐benzoyl‐TN14003, gave a partial, but statistically significant (P≤0.05 (t‐test)) reduction in pulmonary metastasis of MDA‐MB‐231 in SCID mice, even though no attempt was made to inhibit other important targets such as CCR7. These results suggest that T140 analogs have potential use for cancer therapy, and that small molecular CXCR4 antagonists could potentially replace neutralizing antibodies as anti‐metastatic agents for breast cancer.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
