產(chǎn)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].
