4H-1-Benzopyran-4-one, 2,3-dihydro-5,7-dihydroxy-2-(4-hydroxy-2-methoxyphenyl)-8-[(2R)-5-methyl-2-(1-methylethenyl)-4-hexen-1-yl]-, (2S)- Leachianone A Isokurarinone |
Description | Leachianone A, isolated from Radix Sophorae, has anti-malarial, anti-inflammatory, and cytotoxic potent[1]. Leachianone A induces apoptosis involved both extrinsic and intrinsic pathways[2]. |

In Vitro | Leachianone A (0-20 μg/ml; 24-72 hours) exhibits a marked inhibition on the survival of HepG2 cells time- and dose-dependently manner, IC50 values are 6.9 μg/ml, 3.4 μg/ml and 2.8 μg/ml in cells with 24-, 48- and 72-hours treatment, respectively[1]. Leachianone A (10-30 μg/ml; 48 hours) indicates that at low concentration of LA (10 μg/ml), a substantial amount of cells is primarily in the early phase of apoptosis, at higher concentrations, induces a shift of the cell population to late apoptotic/ necrotic stage[1]. Leachianone A (10-30 μg/ml; 48 hours) decreases the precursor of caspase-3 in a dose-dependent manner, reduces the protein level of the pro-forms of upstream initiator caspases, caspases-8 and -9, decreases two downstream substrates, namely inhibitor of caspase-activated DNase(ICAD) and poly-ADP-ribose polymerase (PARP) in HepG2 cells[1]. Cell Viability Assay[1] Cell Line: HepG2 cells Concentration: 0 μg/ml, 2 μg/ml, 4 μg/ml, 6 μg/ml, 8 μg/ml, 10 μg/ml, 12 μg/ml, 14 μg/ml, 16 μg/ml, 18 μg/ml, 20 μg/ml Incubation Time: 24-72 hours Result: Inhibited HepG2 cells survival. Apoptosis Analysis[1] Cell Line: HepG2 cells Concentration: 48 hours Incubation Time: 10, 20, and 30 μg/ml Result: Induced the proportion of annexin V-stained cells in both the early and late apoptotic stage. Western Blot Analysis[1] Cell Line: HepG2 cells Concentration: 48 hours Incubation Time: 10, 20, and 30 μg/ml Result: Decreased the protein expression of caspase-3, caspases-8 and -9, reduced ICAD and PARP protein expression. |
In Vivo | Leachianone A (intravenously injection; 20 mg/kg, 30 mg/kg; once daily; 30 days) significantly diminishes the tumor volume by 17-54% in LA-treated nude mice, when compared with those solely given the vehicle[1]. Animal Model: Male nude mice with human hepatoma HepG2 cells[1] Dosage: 20 mg/kg; 30 mg/kg Administration: Intravenously injection; 20 mg/kg, 30 mg/kg; once daily; 30 days Result: Suppressed the tumor growth in vivo. |
