MedKoo Cat#: 206962 | Name: Exherin TFA
Featured New

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Exherin TFA salt, also known as ADH-1 TFA, is the TFA salt form of exherin, which is a small, cyclic pentapeptide vascular-targeting agent with potential antineoplastic and antiangiogenic activities. ADH-1 selectively and competitively binds to and blocks N-cadherin, which may result in disruption of tumor vasculature, inhibition of tumor cell growth, and the induction of tumor cell and endothelial cell apoptosis. N-cadherin, a cell- surface transmembrane glycoprotein of the cadherin superfamily of proteins involved in calcium-mediated cell-cell adhesion and signaling mechanisms; may be upregulated in some aggressive tumors and the endothelial cells and pericytes of some tumor blood vessels. Note the old CAT# for this product was 201350b

Biological target:
ADH-1, an N-cadherin antagonist, inhibits N-cadherin mediated cell adhesion.
In vitro activity:
The number of viable cells in culture was measured using the CellTiter-Glo luminescent Cell Viability assay (Promega) at 12 h, 24 h and 48 h after addition of ADH-1 (0.25 mg/ml; 0.50 mg/ml and 1 mg/ml). ADH-1 proved to be a potent inducer of cell death in NB cell lines when added at 1 mg/ml. At this concentration, more than 50% of NB cells underwent cell death 24 h after addition (Fig. 5). Interestingly, no effect was seen on the survival of fibroblasts and N-cadherin negative epithelial cells (Fig. 5). These observations were confirmed by flow cytometric determination of PI and FITC-Annexin V levels (Figure S3). Reference: PLoS One. 2012; 7(2): e31206. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3280274/
In vivo activity:
ADH-1 significantly prevented tumor growth in vivo (Fig. 4b). In agreement with the IVIS data, control mice had significantly larger tumors than mice treated with ADH-1 (Fig. 4c). Control mice had significant invasion of tumor nodules into the peritoneal cavity, while tumors in mice treated with ADH-1 were small and were restricted to the pancreas. Figure 5a shows H&E staining of the stomach and a disseminated nodule of a typical control mouse (Fig. 5a, panel a). The tumor occupied the space under the villi of the stomach, indicating that N-cadherin overexpressing BxPC-3 cells were invasive. Figure 5a, panel c shows a tumor localized in the pancreas of a typical mouse treated with ADH-1. Furthermore, H&E staining showed that micro-metastases were present in 4 out of 8 the lungs of control mice (Fig. 5a, panel b), whereas no metastases were seen in mice treated with ADH-1. These data suggest that ADH-1 prevented tumor cell invasion and metastasis in an orthotopic model for pancreatic cancer using N-cadherin overexpressing BxPC-3 cells.
