In friendleukemia virus stain B mice, the brain-to-plasm partition coefficient (Kp, brain) of elacridar is 0.82, 0.43, and 4.31 afterintravenous (2.5 mg/kg), intraperitoneal (100 mg/kg), and o

In Mrp4(-/-)mice, elacridar fully inhibits P-gp mediated transport of topotecan, without siginificant effects on Bcrp1-mediatedtransport5.PROTOCOLKinase Assay 2 10 L of unlabeled cell membrane suspension (at 0.4 mg of protein/mL) are aliquoted into each well

9、 in 96-well plates.5 L of GF120918 are then added to each well. The plate is incubated 25 min at 25C in the dark. 5 L of tritiatedazidopine (1.8 TBq/mmol) (0.6 M in HCI 0.2 mM) are added to each well. After 25 min of incubation at 25C in thedark, samples are simultaneously irradiated for 2 min at 25

10、4 nm at 0C with a thin layer chromatography-designedUV lamp directly in contact with the plate. Samples are solubilized in sodium dodecyl sulfate-polyacrylamide gelelectrophoresis sample buffer but not heated. After separation on a 7.5% polyacrylamide gel, the gel is treated forfluorography with Amp

11、lify and exposed during 3 days onto a photosensitive film. The fluorography is analysed usinga Camag thin layer chromatography Scanner II densitometer.MCE has not independently confirmed the accuracy of these methods. They are for reference only.Cell Assay 3 3.0103 cells per well are seeded in a 96-

12、well plate. After 24 h incubation, an optimum concentration gradient ofelacridar is added to each well. After culturing for 48 h, cell viability is assessed using the proliferation reagent, MTT.Control cells are treated with the vehicle only, 0.1% DMSO. After this final incubation, the medium is asp

13、irated andprecipitated formazan crystals are dissolved in DMSO (100 L/well). The absorbance of each well is measured at 540nm, and a reference wavelength of 650 nm is read with a multiskan JX microplate reader. Cell viability is calculated aspercentage of the control value3.MCE has not independently

14、 confirmed the accuracy of these methods. They are for reference only.Animal Mice are fasted for 3 hr before oral administration of either elacridar (100 mg/kg) or elacridar vehicle. Two hoursAdministration 1 later, crizotinib (5 mg/kg) is administered to mice orally. Blood and brains are isolated 4

15、 hr after crizotinib oraladministration, and processed as described above. The brain concentrations are corrected for the amount of drug inthe brain vasculature. Elacridar hydrochloride is dissolved in dimethyl sulfoxide (106 mg/mL) in order to get 100 mgpure elacridar per 1 mL of dimethyl sulfoxide

16、. The stock solution is further diluted with a mixture of Polysorbate 80,ethanol and water 20:13:67 (v/v/v) to yield a concentration of 10 mg/mL pure elacridar.Page 2 of 3 www.MedChemEMCE has not independently confirmed the accuracy of these methods.
