E7820 is an angiogenesis inhibitor by suppressing integrin a2, a cell adhesion molecule expressed on endothelial cells. In Vitro: E7820 treatment inhibits proliferation of HUVEC induced by either bFGF and VEGF in serum-free medium with IC₅₀ values of 0.10 and 0.081 ug/mL, respectively. E7820 also inhibits both bFGF- and VEGF-driven tube formation of HUVEC in this assay. The IC₅₀ values are 0.20 and 0.24 ug/mL, respectively^[3]. In Vivo: E7820 (50 mg/kg) with erlotinib has a significantly synergistic antitumor effect in three xenograft models without severe body weight loss. E7820 (50 mg/kg) and erlotinib decrease MVD and enhance apoptosis in tumor-associated endothelial cells, inhibit tumor cell proliferation and enhanced apoptosis, and enhance inhibition of cell proliferation and apoptosis through activation of both intrinsic and extrinsic apoptosis pathways in human NSCLC xenograft models^[1]. E7820 shows anti-tumor activity at doses of 50, 100, and 200 mg/kg in the tumor growth and alpha2-integrin expression experiments^[2]. E7820 (50, 100, and 200 mg/kg) inhibits tumor growth in a dose-dependent manner in all s.c. xenograft models. E7820 completely inhibits s.c. tumor growth of LoVo tumor cells and also regresses the tumor mass of KP-1 tumor cells at the dosages of both 100 and 200 mg/kg^[3].
