E7820
Based on 5 publication(s) in Google Scholar
E7820 (ER68203-00), an orally active aromatic sulfonamide derivative, is a molecular glue that induces the targeted degradation of splicing factor RBM39 by recruiting the E3 ubiquitin ligase CUL4-RBX1-DDB1-DCAF15 (CRL4DCAF15). E7820 is an 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. E7820 can be used for the study of acute myeloid leukemia (AML).

Biological Activity
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].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
E7820 (200-400 mg/kg; p.o.;once daily for 4 days) potently inhibits WiDr-induced angiogenesis[1].

-
Animal Model:Six-week-old female nude mice (KSN mice, WiDr-induced angiogenesis model) [1]
-
Dosage:50, 100, 200 mg/kg
-
Administration:p.o. ; twice daily for 14 days from 2 days after inoculation of the tumor cells
-
Result:The antitumor effect was dose-dependent at 50, 100, and 200 mg/kg, and the tumor growth rates were 52%, 46%, and 27%, respectively.
