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.
