Biological Activity

BH3I-1 inhibits Bcl-xL heterodimerization in vitro. It also induces cytochrome c release. BH3I-1, while inhibiting its reported target Bcl-2/Bim and Bcl-xL/Bim, shows significant inhibition of both the p53/hDM2 and p300/Hif-1a interactions.

Cell Experiment
Cell lines Jurkat cells
Preparation method Cells (5×10^4 cells per well) are seeded into white 96-well plates (Costar) and treated with various concentrations of the compounds for 48 h. For zVAD-FMK protection experiments, cells are preincubated with 100 µM zVAD-FMK for 1 h before the addition of chemicals. Cell viability is determined with an MTS assay. For PI staining experiments, cells are grown in 24-well plates and then incubated with 2 µg ml/L PI. Cell death is determined by FACS analysis.
Concentrations 30 or 90 μM
Incubation time 48 h

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
