| Description | |
|---|---|
| Overview | A cell-permeable coumarin o-hydroxyaldehyde that inhibits IRE1 RNase activity in a time- and dose-dependent manner (IC50 = 550 and 45 nM, respectively, with 0 and 16 min drug preincubation in RNA cleavage assays) by covalently targeting IRE1 Lys907 via Schiff base formation, effectively preventing ER stress-induced site-specific mRNA splicing as well as RIDD (Regulated IRE1-Dependent Degradation) mRNA degradation (IC50 = 6.9 and 4.1 µM, respectively, against Xbp1 splicing and Scara3 degradation) in MEF cultures following Tunicamycin (Cat. No. 654380) treatment. Comparing to STF083010 (Cat. No. 412510), 4μ8C is also shown to inhibit IRE1 autophosphorylation in cell-free assays via Schiff base formation with IRE1 Lys599 in the absence of ADP, however cellular nucleotide prevents 4μ8C from targeting IRE1 Lys599 intracellularly. |
