Biological Activity

PF-2341066 (Crizotinib) is a potent, orally bioavailable, ATP-competitive small-molecule inhibitor of c-Met kinase and ALK (anaplastic lymphoma kinase) with IC50 values to be 4 and 25 nM for C-Met and ALK resepectively.PF-2341066 (Crizotinib) potently inhibited cell proliferation, which was associated with G1-S–phase cell cycle arrest and induction of apoptosis in ALK-positive ALCL cells (IC50 values=30 nM) but not ALK-negative lymphoma cells. The induction of apoptosis was confirmed using terminal deoxyribonucleotide transferase–mediated nick-end labeling and Annexin V staining (IC50 values=25–50 nM).

Method Cell proliferation assay
Cell Lines HNE -1 cells
Concentrations 0.79±0.21 μmol/L
Incubation Time 48 h
Results The half maximal inhibitory concentration of PF-2341066 alone is 0.79±0.21 μmol/L, while combination with cisplatin is 0.41±0.13 μmol/L. The inhibition rate increased by 23.4% and showed certain synergistic effects
Cell Experiment
Cell lines Karpas299, SUDHL-1, or U-937 cells
Preparation method Cell Proliferation/Survival Assays. Cells were seeded in 96-well plates at low density at 37°C in medium supplemented with 10% FBS (growth medium) and after 24 h were switched to low serum medium (2% FBS). Designated concentrations of PF-2341066 were added to each well and cells were incubated at 37°C for 72 h. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay (Promega) was done to determine the relative cell numbers. IC50 values were calculated by concentration-response curve fitting using a Microsoft Excel–based four-parameter analytic method.

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