| 体内研究: |
In the GTL-16 model, PF-2341066 reveals the ability to cause marked regression of large established tumors (>600 mm3) in both the 50 mg/kg/day and 75 mg/kg/day treatment cohorts, with a 60% decrease in mean tumor volume over the 43-day administration schedule. In an another study, PF-2341066 displays the ability to completely inhibits GTL-16 tumor growth for >3 months, with only 1 of 12 mice exhibiting a significant increase in tumor growth over the 3-month treatment schedule at 50 mg/kg/day. In the NCI-H441 NSCLC model, a 43% decrease in mean tumor volume is observed at 50 mg/kg/day during the 38-day PF-2341066 administration cycle. In the Caki-1 RCC model, a 53% decrease in mean tumor volume is observed to be associated with decreased volume of each tumor by at least 30% at 50 mg/kg/day during the 33-day PF-2341066 administration cycle. PF-2341066 also reveals near-complete prevention of the growth of established tumors at 50 mg/kg/day in the U87MG glioblastoma or PC-3 prostate carcinoma xenograft models, with 97% or 84% inhibition on the final study day, respectively. In contrast, PF-2341066 p.o. given at 50 mg/kg/day does not significantly inhibit tumor growth in the MDA-MB-231 breast carcinoma model, or the DLD-1 colon carcinoma model. A significant dose-dependent reduction of CD31–positive endothelial cells is observed at 12.5 mg/kg/day, 25 mg/kg/day, and 50 mg/kg/day in GTL-16 tumors, indicating that inhibition of MVD shows a dose-dependent correlation to antitumor efficacy.

Cell lines: GTL-16 gastric carcinoma cells and T47D breast carcinoma cells Concentrations: 0-256 nM Incubation Time: 1 h Method: Cells including GTL-16 gastric carcinoma cells and T47D breast carcinoma cells are seeded in 96-well plates in media supplemented with 10% fetal bovine serum (FBS) and transferred to serum-free media [with 0.04% bovine serum albumin (BSA)] after 24 hours. In experiments investigating ligand-dependent RTK phosphorylation, corresponding growth factors are added for up to 20 minutes. After incubation of cells with PF-2341066 for 1 hour and/or appropriate ligands for the designated times, cells are washed once with HBSS supplemented with 1 mM Na3VO4, and protein lysates are generated from cells. Subsequently, phosphorylation of selected protein kinases is assessed by a sandwich ELISA method using specific capture antibodies used to coat 96-well plates and a detection antibody specific for phosphorylated tyrosine residues. Antibody-coated plates are (a) incubated in the presence of p |
