General description
A cell-permeable CFTRinh-172 (Cat. No. 219670) 2-oxo analog that exhibits ~25-fold higher aqueous solubility than the 2-thioxo CFTRinh-172 (420 µM vs. 17 µM, respectively, in PBS with 2% DMSO at 25 °C) and great potency, albeit slightly weaker than that of CFTRinh-172, in inhibiting CFTR-mediated apical membrane chloride current upon 20 µM Forskolin (Cat. No. 344270) stimulation in CFTR-expressing FRT cells (IC50 = 1.4 µM vs. 0.38 µM with CFTRinh-172) with practically no cytotoxicity (91% of no-drug control FRT in viability assay; 48 h at 50 µM).
Packaging
Packaged under inert gas
Warning
Toxicity: Irritant (B)

Many diseases are driven by proteins that are aberrantly ubiquitinated and degraded. These diseases would be therapeutically benefited by targeted protein stabilization (TPS). Here we present deubiquitinase-targeting chimeras (DUBTACs), heterobifunctional small molecules consisting of a deubiquitinase recruiter linked to a
