In Vitro	Retrorsine (60-240 μM; 24 hours) significantly reduces HSEC-CYP3A4 cells viability, depletes GSH, and increases formation of pyrrole-protein adducts[3]. Cell Viability Assay[3] Cell Line: HSEC-CYP3A4 cells Concentration: 60 μM, 120 μM , 240 μM Incubation Time: 24 hours Result: Significantly decreased cell viability.
In Vivo	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[1]. Animal Model: Male Wistar rats (180±20 g), portal branch ligation (PBL) model[1] Dosage: 30 mg/kg Administration: Intraperitoneal injection, twice, separated by 2-week interval Result: Strongly impaired the liver weight gain, protein and DNA synthesis as well as induction of cell cycle related proteins in the regenerating lobes after PBL.
