UsesCR-1-31-B is a synthetic rocaglate and a potent eIF4A inhibitor. CR-1-31-B exhibits powerful inhibitory effects over eIF4A by perturbing the interaction between eIF4A and RNA, sequentially impeding initiation during protein synthesis. CR-1-31-B perturbs association of Plasmodium falciparum eIF4A (PfeIF4A) with RNA. CR-1-31-B induces apoptosis of neuroblastoma and gallbladder cancer cells[1][2][3][4].
in vivo

CR-1-31-B (2 mg/kg in 60 μL olive oil; IP; once every 2 days for 28 days) reduces the growth and initiates TRAIL-induced apoptosis in a BALB/c nude mice model of gallbladder cancer cells (GBC)[2].
CR-1-31-B (0.2 mg/kg; IP; daily for 7 days; murine orthotopic transplant model of pancreatic ductal adenocarcinoma) effectively inhibits protein synthesis and growth of pancreatic tumours[5].
