The caspase-3 activity is measured using a caspase-3 activity assay kit. Briefly, the cells treated by different concentrations of Sanguinarine (0.5 μM, 1 μM, 2 μM, 4 μM) or control DMSO are collected, washed and lysed in a lysis buffer for 30 min on ice. The supernatants are then collected by centrifuging at 1,2000 rpm for 10 min. The Ac-DEVD-pNA (2 mM) is added to each sample and incubated at 37°C for 1 h. The optical density (OD) of each sample is finally quantified at a wavelength of 405 nm using a spectrophotometer. The p-NA standard is used to calibrate the caspase-3 activity of each sample^[1].

The cell viability of Sanguinarine is determined by CCK-8 assay using a cell counting kit-8. Briefly, 22B-cFluc cells are seeded in a 96-well plate (5×10³ cells/well) and treated with different concentrations of Sanguinarine (0.5 μM, 1 μM, 2 μM, 4 μM) for 24 h. Then 10 mL CKK-8 is added to each well for 4 h and the absorbance at 450 nm is measured with a microplate reader. The optical density (OD) values are determined to reflect the viable cell populations from each well^[1].

Mice^[1]
Xenografted tumor models are prepared by injection of 1×10⁷ 22B-cFluc cells suspended in PBS into nude mouse (n=6). After tumors reach a volume of approximately 100 mm³, Sanguinarine (10 mg/kg) is i.v. injected into mice. After injection for 24 h, 48 h and 72 h, mice are given a single i.p. dose of 150 mg/kg D-luciferin and bioluminescence imaging are performed using a Xenogen Lumina II system. The signal intensity in the region of interest is expressed using the Living Image software 4.1. For the anti-tumor therapy studies, one group of tumor-bearing mice (n=6) receive intravenously 10 mg/kg of Sanguinarine every other day throughout the experimental period, while the control group of mice (n=6) receive DMSO only. Tumor growth measurement is calculated^[1].
