Yellow crystalline powder, soluble in organic solvents such as methanol, ethanol, DMSO, etc., derived from Rheum officinale. | [Uses]
Rhapontigenin is a natural analog of resveratrol with antioxidant and anti-cancer activity. It is a mechanism-based, selective inactivator of cytochrome P450 1A1 (IC50 = 400 nM), an aryl hydrocarbon hydroxylase which activates polycyclic aromatic hydrocarbons that act as procarcinogens. At higher concentrations, rhapontigenin inhibits the proliferation of HepG2 and HL-60R cancer cell lines (IC50 = 48 μM).[Cayman Chemical] | [Definition]
ChEBI:Rhapontigenin is a stilbenoid. | [in vivo]
Rhapontigenin (intraperitoneal injection; 25mg/kg) shows significant protection from death due to pulmonary thrombosis in mice, those samples are orally administered 90 min before tail vein injection of epinephrine and collagen[3]. | Animal Model: | ICR mice[3] | | Dosage: | 25mg/kg | | Administration: | 25mg/kg; intraperitoneal injection | | Result: | Showed anti-thrombosis activity with 60% protection. |
