Application
PYR-41 has been used as E1 inhibitor:
- to determine the cellular degradation pathways on adeno-associated viruses (AAV) transduction
- to assess its selectivity and potency by matrix assisted laser desorption/ionization-time of flight (MALDI-TOF) E2/E3 assay
- to treat fully differentiated C2C12 myotubes in high glucose medium for determining its effect on protein ubiquitination and cell viability
- in the pretreatment of human brain microvascular endothelial cells (hBMECs) for the inhibition studies before infection with bacteria
Biochem/physiol Actions
PYR-41 inhibits E1 ubiquitin ligases like mouse double minute 2 homolog (MDM2), Itchy (ITCH) and HOIL-1L interacting protein (HOIP). It has anticancer potential.
PYR-41 is a cell permeable inhibitor of Ubiquitin activating enzyme (E1) with little or no activity against E3, E2, or caspase enzymatic activity.
PYR-41 is a cell permeable inhibitor of Ubiquitin activating enzyme (E1).

Erythrophagocytosis, the phagocytic removal of damaged red blood cells (RBC), and subsequent phagolysosome biogenesis are important processes in iron/heme metabolism and homeostasis. Phagolysosome biogenesis implies the interaction of nascent phagosomes with endocytic compartments and also autophagy effectors. Here, we report
