NCIt definition : A small molecule and aromatic sulfonamide derivative with potential antiangiogenic
and antitumor activities. E7820 inhibits angiogenesis by suppressing integrin alpha
2, a cell adhesion molecule expressed on endothelial cells. Inhibition of integrin
alpha 2 leads to an inhibition of cell-cell interactions, endothelial cell-matrix
interactions, vascular endothelial cell proliferation and angiogenesis.;
