Application

Retrorsine has been used:
  • as a mito-inhibitory pyrrolizidine alkaloid compound to induce necrotic liver injury in rats
  • to induce hepatocellular injury in rats
  • to arrest endogenous hepatocyte growth in mice

Biochem/physiol Actions

Retrorsine (RTS) is a retronecine-type pyrrolizidine alkaloid associated with Senecio and Crotalaria species. It belongs to the pyrrolizidine alkaloid family with mito-inhibitory property and elicits hepatotoxicity. It mediates the inactivation of cytochrome P450 3A4. Retrorsine also inhibits replication of fully differentiated hepatocytes.
