CR-1-31-B (C007B-343057)

CR-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 cellsIn VitroCR-1-31-B (100 nM; 24 hours) inhibits MUC1-C translation in MCF-10A cells (EGF-stimulated). ?/nCR-1-31-B (10 and 100 nM) decreases MUC1-C abundance in MDA-MB-468 breast cancer cells. ?/nCR-1-31B sensitizes gallbladder cancer cells to TRAIL-mediated apoptosis through the translational downregulation of c-FLIP. ?/nNeuroblastoma (NB) cell lines exhibit decreased viability, increased apoptosis rates as well as changes in cell cycle distribution when treated with the synthetic rocaglate CR-1-31-B (24-72 hours), which clamps eIF4A and eIF4F onto mRNA, resulting in a translational block . ?/nCR-1-31-B (100 nM; 5 hours) treatment increases reverse glutamine metabolism in pancreatic cancer cells . MCE has not independently confirmed the accuracy of these methods. They are for reference only. Western Blot AnalysisCell Line: MCF-10A cells (EGF-stimulated) Concentration: 100 nM Incubation Time: 24 hours Result: Blocked increases in MUC1-C abundance. Cell Viability Assay Cell Line: SH-SY5Y cells and Kelly cells Concentration: 0.1-100 nM Incubation Time: 24-72 hours Result: A significant decrease in SH-SY5Y viability was observed at 10 nM for all time points. Significantly decreased the viability of Kelly cells at 5 nM. The calculated IC 50 at 48 h was 20 nM for SH-SY5Y and 4 nM for Kelly cells. Apoptosis Analysis Cell Line: SH-SY5Y and Kelly cells Concentration: SH-SY5Y cells were treated with 10, 20, and 50 nM and Kelly cells with 1, 5, and 10 nM Incubation Time: 24-72 hours Result: Triggered apoptosis.In VivoCR-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). ?/nCR-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.
