Application

ATN-161 has been used as an inhibitor of integrin α5β1 and αvβ3 in cultured platelet endothelial cell adhesion molecule (PECAM1)-positive endothelial cells isolated from AL (CECAL).

Biochem/physiol Actions

ATN-161 is a non-RGD based integrin binding peptide derived from the synergy region of fibronectin that inhibits the receptors for integrins alpha-v beta-3 and integrin alpha-5 beta-1. Integrin alpha-5 beta-1 is expressed on endothelial cells and plays a key role in endothelial cell adhesion and migration and may also play a key role in cancer cell invasion and metastasis. ATN-161 was shown to have antiangigenic and antitumor activity.

The wet form of age-related macular degeneration (AMD) is a leading cause of blindness among elderly Americans and is characterized by abnormal vessel growth, termed choroidal neovascularization (CNV). Integrin α5β1 is a transmembrane receptor that binds matrix macromolecules and proteinases

Endothelial cell interactions with transitional matrix proteins, such as fibronectin, occur early during atherogenesis and regulate shear stress-induced endothelial cell activation. Multiple endothelial cell integrins bind transitional matrix proteins, including α5β1, αvβ3, and αvβ5. However, the role these integrins play

To evaluate the toxicity, pharmacological and biological properties of ATN-161, a five -amino-acid peptide derived from the synergy region of fibronectin, adult patients with advanced solid tumours were enrolled in eight sequential dose cohorts (0.1-16 mg kg(-1)), receiving ATN-161 administered
