Cell lines | MDA-MB-231, PC3, HCT116, 22RV1, MCF7 and IMR90 cells |
Preparation method | Culturing MDA-MB-231, PC3, HCT116 cells in RPMI with 10% FBS, 22RV1 cells in alphaMEM and 10% FBS, MCF7 and IMR90 cells in DMEM with 10% FBS. Treating cells with inhibitors for 48 h. The media is removed and replaced with DMEM 10% FBS without phenol red supplemented with 1mg/mL of MTT and incubated for 1–2 h. Live cells reduce yellow MTT to purple formazan. The resulting formazanis solubilized in acidified isopropanol and 1% Triton. Formazan signal absorbance is measured at 570 nm and corrected for the 650 nm background. IC50s are calculated using GraphPad Prizm statistical package with sigmoidal variable slope dose response curve fit |

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 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 Compound A of 10 mg/kg.
