Biological Activity

[Description]:

Insulin efsitora alfa (LY-3209590) is a selective agonist of insulin receptor (IR). Insulin efsitora alfa is a fusion protein composed of human IR agonists fused with the crystallizable (Fc) domain of human immunoglobulin G2 (IgG2) fragment, with a molecular weight of 64.1 kDa. Insulin efsitora alfa is well tolerated and has potential applications in diabetes patients[1].

[In Vitro]

Insulin efsitora alfa (0.01-100 nM) 在 HEK293 细胞中刺激人胰岛素受体同种型 A (hIR-A) 和人胰岛素受体亚型 B (hIR-B) 磷酸化，EC50 值分别为 4241 nM和 391 nM[2]。 Insulin efsitora alfa (20 µM；30 min) 显著促进 hIR-A 和 hIR-B 去磷酸化[2]。 Insulin efsitora alfa 刺激 3T3-L1 脂肪细胞的脂质生成和 SAOS-2 与 H4IIE 细胞的细胞增殖，EC50 值分别为 19 nM、134 nM 和 20 nM[2]。

[In Vivo]

Insulin efsitora alfa (3、10 和 30 nmol/kg；皮下注射；单剂量) 在使用链脲佐菌素 (Streptozotocin，HY-13753) 治疗的糖尿病大鼠中显著降低了血糖[2]。
