| In Vitro | 0.1 mM NPPB in the bath solution reduces channel open probability from 0.89±0.06 to 0.11±0.04 (n=5, P<0.01)[1]. Dose-dependent inhibition of chloride currents is observed with a 50% inhibitory concentration (IC50) of 125 μM NPPB. NPPB itself also shows cytotoxicity against glioma cells with a GI50 of approximately 500 μM[2]. |
| Cell Assay | Cells are seeded in the 96-well microtiter plate at a density of 5×103 cells per well and incubated at 37°C for 24 h in a humidified 5% CO2 atmosphere. After removing the culture medium, fresh media containing various concentrations of NPPB is added, and incubated for 24 h. Next, 100 μL of Thiazolyl blue tetrazolium bromide at 0.5 mg/mL is added to each well and incubated at 37°C for 1 h. Cells are then dissolved in 100 μL of DMSO, and the absorbance is measured at 570 nm with a Microplate Reader. Concentration-response curves of NPPB are fitted to a Hill equation to obtain GI50 and GI80 (50% and 80% growth inhibition concentrations, respectively) values[2]. |
