E-4177 is an angiotensin type 1 receptor antagonist potentially for the treatment of hypertension. In rat adrenal cortex and liver, E4177 competitively inhibited the specific binding of 125I-[Sar1,Ile8]Ang II, with IC50 being (5.2 +/- 1.0) x 10(-8) M for the adrenal cortex and (1.2 +/- 0.3) x 10(-7) M for the liver. These IC50 values were similar to those for losartan, which showed an IC50 of (6.0 +/- 0.9) x 10(-8) M for the adrenal cortex and (1.3 +/- 0.5) x 10(-7) M for the liver. E4177 is a potent AT1 Ang II-receptor antagonist that may be clinically useful for the treatment of cardiovascular diseases such as hypertension.

E4177 (57G709) 是一种具有口服活性的血管紧张素 (AngII) 受体拮抗剂。E4177 可以抑制血管平滑肌细胞 (HASMC) 细胞的生长和细胞表面积的增大。此外，E4177 也可以增加血小板原性生长因子 (PDGF) 受体表达。E4177 可用于血管疾病的研究。
