R-IMPP
Based on 1 Customer Validation
R-IMPP (PF-00932239) is a PCSK9 translation inhibitor and a selective 80S ribosome binder. R-IMPP inhibits the KRAS/MEK/ERK signaling cascade. R-IMPP reduces LPS-induced nuclear translocation of NFkB P65. R-IMPP increases LDL-R levels in cells, promotes LDL-C uptake, and does not alter the secretion of transferrin or albumin. R-IMPP inhibits the growth of colorectal cancer (CRC) cells, organoids and xenografts carrying APC/KRAS mutations, as well as the number and burden of spontaneous mouse tumors. R-IMPP can be used in research related to colorectal cancer with APC/KRAS mutations, hepatic ischemia-reperfusion injury and hypercholesterolemia.

R-IMPP (30-60 μM) inhibits the KRAS/MEK/ERK pathway by reducing the protein levels of p-ERK and cyclin D3 in three APC/KRAS-mutant colorectal cancer cell lines, HCT116, LOVO and SW1116[1].
R-IMPP (40 μM) inhibits the expression of active KRAS protein in SW1116 APC/KRAS mutant colorectal cancer cells[1].
R-IMPP (72 h) inhibits cell viability, with stronger inhibitory potency against APC/KRAS mutant colorectal cancer cell lines (72-hour IC50: 17.6-41.8 μM). In comparison, the 72-hour IC50 is 84.8 μM for wild-type 1CT cells and 57.5 μM for normal NCM460 colon cells[1].
R-IMPP (30-60 μM; 24 h) potently inhibits the expression of PCSK9 protein in AML12 hepatocytes[2].
R-IMPP (60 μM; 24 h) impairs the mitochondrial membrane potential of AML12 hepatocytes, while no such effect is observed at the concentration of 30 μM[2].
R-IMPP attenuates hypoxia/reoxygenation-induced apoptosis of AML12 hepatocytes[2].
R-IMPP potently inhibits PCSK9 secretion in CHO-K1 cells expressing recombinant ProLabel-tagged PCSK9, with an IC50 of 4.8 μM. Meanwhile, it exhibits only extremely low cytotoxicity and no non-universal secretion inhibitory effect[3].
R-IMPP (3-30 μM; overnight pre-treatment) promotes the uptake of AF-LDL by Huh7 cells, with a 47.5% increase in uptake at the concentration of 30 μM[3].
