In vitro study | 4 gi-1 disrupts the eIF4F complex and inhibits Cap-mediated translation in vitro. 4 gi-1 has pro-apoptotic activity in Jurkat cells, and can effectively inhibit cell growth in A549 lung cancer cells, and its IC50 value is about 6 μm. In human lung cancer cells, 4gi-1 increases TRAIL-induced apoptosis by inducing DR5 and down-regulating c-FLIP, separate inhibition of cap-dependent protein translation. In addition, in chronic lymphocytic carcinoma, 4gi-1 restores sensitivity to ABT-737 through cap-dependent and non-dependent mechanisms. 4 gi-1 disrupts the eIF4F complex and inhibits Cap-mediated translation in vitro. 4 gi-1 has pro-apoptotic activity in Jurkat cells, and can effectively inhibit cell growth in A549 lung cancer cells, and its IC50 value is about 6 μm.
