General description

A cell-permeable pyrazone compound that irreversibly (presumably via covalent modification) inhibits ubiquitin-activating enzyme E1 activity (IC50<10 µM in cell-free E1 ubiquitination reactions), while exhibiting little or no activity against E3, E2, or caspase enzymatic activity. Blocks ubiquitination-dependent protein degradation and other ubiquitination-mediated cellular activities. E1 inactivation by PYR-41 or other means has been shown to result in an overall elevation of sumoylation.

Packaging

Packaged under inert gas

Warning

Toxicity: Irritant (B)

Reconstitution

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 1 month at -20°C. At room temperature, compound will undergo ~1% decomposition per day.

The NOD1/2-RIPK2 is a key cytosolic signaling complex that activates NF-κB pro-inflammatory response against invading pathogens. However, uncontrolled NF-κB signaling can cause tissue damage leading to chronic diseases. The mechanisms by which the NODs-RIPK2-NF-κB innate immune axis is activated and
