n-Butyl-β-D-fructofuranoside could be isolated from kangaisan. n-Butyl-β-D-fructofuranoside induces apoptosis through the mitochondrial pathway. n-Butyl-β-D-fructofuranoside can be used for cancer research In Vitro n-Butyl-β-D-fructofuranoside (0-23.6 μg/mL; 24-78 hours) has antiproliferation activity and inhibits the viability of Bel-7402 cells. n-Butyl-β-D-fructofuranoside (0-75 μg/mL; 0-72 hours) inhibits BEL-7402 cells by interfering with cell cycle and inducing apoptosis. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Cell Viability AssayCell Line: Bel-7402 cells Concentration: 0.47, 2.95, 5.90, 11.8, 17.7 and 23.6 μg/mL Incubation Time: 24, 48 and 72 hours Result: Inhibited the proliferation of Bel-7402 cells at both time- and dose-dependent manner. Cell Cycle AnalysisCell Line: Bel-7402 cells Concentration: 0, 50 and 75 μg/mL Incubation Time: 24, 48 and 72 hours Result: Induced cell cycle arrest at G0/G1 phase. Western Blot AnalysisCell Line: Bel-7402 cells Concentration: 23.6 μg/mL Incubation Time: 0, 24, 48 and 72 hours Result: Decreased Bcl-2 and increased Bax and p53 levels in a time manner. Form:Oil IC50& Target:Bax Bcl-2
