Aflatoxin B2-13C17(AFB2-13C17) is intended for use as an internal standard for the quantification of AFB2by GC- or LC-MS. AFB2is a mycotoxin that has been found inA. terricola.1It induces hepatic autophagy and apoptosis in broiler chickens when administered at doses of 0.2, 0.4, and 0.8 mg/kg.2AFB2(0.5 and 1 mg/animal) also induces parenchymal cell hyperplasia in rats.3

c-MET degrader. Comprises MET inhibitor foretinib (GSK 1363089; Cat. No. 6056) joined by a linker to a von Hippel-Lindau (VHL) recruiting ligand. Degrades c-MET within 6 hours in vitro. Inhibits agonist-driven AKT phosphorylation and GTL16 cell proliferation (IC50 = 66.7 nM). Also degrades exon-14-deleted c-MET in Hs746T cells.
TBK1/IKKε-IN-4 is a 6-aminopyrazolopyrimidine derivative and a potent, selective TBK1 and IKKε inhibitor with IC50 values of 13 nM and 59 nM, respectively. TBK1/IKKε-IN-4 shows 100- to 1000-fold less activity against other protein kinases including PDK1, PI3K family members and mTOR[1].
TBK1/IKKε-IN-4 (Compound II; 96 hours; A549 andHCC44 cells) treatmentdisplays selective toxicity in TBK1-dependent cancer cell lines (IC50 of ~ 4.2 μM for H441 cells and IC50 of ~0.4 μM for A549 cells)[1].TBK1/IKKε-IN-4 (Compound II; 0-2 μM; 30 minutes; HCC44 cells) treatment inhibits the AKT activity[1].TBK1/IKKε-IN-4 (Compound II) inhibits LPS-induced expression of IFNβ (IC50 =62 nM), and the IFNβ target genes IP10 (IC50 =78 nM) and Mx1 (IC50=20 nM). TBK1/IKKε-IN-4 effectively blocksTLR3-dependent IRF3 nuclear translocation in cells with an IC50 under 100 nM, but does not impair TNFR1-dependent p65 NFκB nuclear translocation with doses as high as 20 μM[1].
