Exherin - CAS# 229971-81-7

Exherin, also known as ADH-1, 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 201350A

How to use

In Vitro:

ADH-1 (0.2 mg/mL) blocks collagen I-mediated changes in pancreatic cancer cells, and is highly effective at preventing cell motility that is induced by expression of N-cadherin. ADH-1 (0, 0.1, 0.2, 0.5 and 1.0 mg/mL) induces apoptosis in a dose-dependent and N-cadherin-dependent manner.

In Vivo:

ADH-1 (50 mg/kg) significantly prevents tumor growth and metastasis in a mouse model for pancreatic cancer. ADH-1 prevents tumor cell invasion and metastasis in an orthotopic model for pancreatic cancer using N-cadherin overexpressing BxPC-3 cells. ADH-1, at the dosages evaluated, does not display either antiangiogenic activity in a rat aortic ring assay or antitumor potential in a PC3 subcutaneous xenograft tumor model. ADH-1 (10 mL/kg, i.p.) augmentation of melanoma tumor growth is overcome through its ability to make regionally infused melphalan more effective. ADH-1 mediated augmentation of melanoma tumor growth is not altered by regionally infused temozolomide. In A375, but not DM443 xenografts, ADH-1 treatment increases phosphorylation of AKT at serine 473. ADH-1 slightly diminishes N-cadherin expression in both xenografts.
