E7820 (ER68203-00), an orally active aromatic sulfonamide derivative, is a unique angiogenesis inhibitor suppressing an expression of integrin alpha2 subunit on endothelium. E7820 inhibits rat aorta angiogenesis with an IC₅₀ of 0.11 μg/ml. E7820 modulates α-1, α-2, α-3, and α-5 integrin mRNA expression. Antiangiogenic and antitumor activity^[1][2].

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^[1].
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^[1].

E7820 (ER68203-00) (50-200 mg/kg; p.o. ; twice daily for 14 days) delays the growth of WiDr cells inoculated s.c.^[1].
E7820 (200-400 mg/kg; p.o.;once daily for 4 days) potently inhibits WiDr-induced angiogenesis^[1].
