Retrorsine is a naturally occurring toxic pyrrolizidine alkaloid. Retrorsine can bind with DNA and inhibits the proliferative capacity of hepatocytes. Retrorsine can be used for the research of hepatocellular injury[1][2].
Retrorsine (60-240 μM; 24 hours) significantly reduces HSEC-CYP3A4 cells viability and GSH levels, and increases formation of pyrrole-protein adducts[3].
Retrorsine (30 mg/kg; i.p.; twice) impairs liver regeneration in the PBL model not only by an S or G2/M phase block, but also by a block located before the G1/S transition of the cell cycle[4].
