E7820 is a α2 integrin inhibitor 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.

How to use

In Vitro:

E7820 (ER68203-00) inhibits both bFGF- and VEGF-driven ube formation of human umbilical vascular endothelial cell (HUVEC) in a dose-dependent manner with IC50 of 0.20 and 0.24 μg/ml, respectively. E7820 inhibits proliferation of HUVEC induced by either bFGF or VEGF in serum-free medium (SFM). The IC50 values are 0.10 and 0.081 μg/ml, respectively. Antiproliferative activity of E7820 against both WiDr and LoVo cells is very weak compared with that against HUVEC. The values of IC50 were 29 and 15 μg/ml, respectively.

In Vivo:

E7820 (ER68203-00) (50-200 mg/kg; p.o. ; twice daily for 14 days) delays the growth of WiDr cells inoculated s.c.. E7820 (200-400 mg/kg; p.o.;once daily for 4 days) potently inhibits WiDr-induced angiogenesis.
