Cell lines | Jurkat cells |
Preparation method | The solubility of this compound in DMSO is >22.6 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 ℃ for several months. |
Reacting condition | 0 ~ 200 μM; 24 hrs |
Applications | In Jurkat cells, 4EGI-1 (>50 μM) treatment induced cell death after 24 hrs. In addition, 4EGI-1 significantly increased subG1 DNA content, which was inhibited by cotreatment with the caspase inhibitor zVAD-FMK. |
产品描述 | 4EGI-1 is an inhibitor of eIF4E/eIF4G interaction, with a Kd of 25 μM against eIF4E binding. 4EGI-1 is an inhibitor of eIF4E/eIF4G interaction, with a Kd of 25 μM against eIF4E binding. 4EGI-1 disrupts the eIF4F complex and inhibits expression of oncogenic proteins in mammalian cells. 4EGI-1 (0-40 μM) also exhibits proapoptotic activity and inhibits the growth of multiple cancer cell lines[1]. 4EGI-1 is cytotoxic to breast cancer cells, such as SKBR-3, MCF-7 and MDA-MB-231 cells, with the IC50 of appr 30 μM, and to the non-CSCs (Cancer stem cells), the IC50 is about 22 μM. 4EGI-1 enhances breast CSC differentiation (40 μM), and suppresses breast CSC induced HUVEC tube-like structure formation (8 μM). Moreover, 4EGI-1 selectively inhibits translation that persists in CSC maintenance and dissemination[2]. 4EGI-1 (50 μM) impairs the formation of eIF4F complex in U87 cells. 4EGI-1 (10, 50 and 100 μM) inhibits cell proliferation via inducing apoptosis in U87 cells, and the apoptosis is via Bax activation. 4EGI-1 causes mitochondrial dysfunction, and induces ER stress via GRP-78 activation, in U87 cells[3]. 4EGI-1 (75 mg/kg, i.p.) inhibits breast cancer stem cells (CSC) tumor growth and tumorangiogenesis in vivo[2]. 4EGI-1 (75 mg/kg, i.p.) shows inhibitory effect on the tumor volume and weight in mice bearing U87 cells[3].
