| 体外研究： |
PF-03084014 inhibits Notch receptor cleavage in HPB-ALL cells that harbor mutations in both the heterodimerization and PEST domains in Notch1 (IC50: 13.3 nM). PF-03084014 downregulates Notch target genes Hes-1 (IC50<1 nM) and cMyc expression (IC50:10 nM) in HPB-ALL cells, respectively. PF-03084014 inhibits cell growth of a subset of human T-ALL cell lines (HPB-ALL, DND-41, TALL-1, and Sup-T1) through induction of cell cycle arrest and apoptosis (IC50s: 30-100 nM). PF-03084014 reduces proliferation of HUVECs (IC50: 0.5 μM) and decreases the lumen formation (IC50: 50 nM). PF-03084014 (1 μM) has no antiproliferative effect in MX1 cells; however, it inhibits migration by 95%. |
| 体内研究： |
PF-03084014 (200 mg/kg, p.o.) causes maximal NICD inhibition for ∼80% in xenograft HPB-ALL tumors. PF-03084014 shows robust antitumor activity in this mode with a maximal tumor growth inhibition of 92% at the dose of 150 mg/kg, accompanied by a significant reduction of NICD/Notch1, tumor mitotic index (Ki67), and apoptosis (activated caspase-3) staining. PF-03084014 (120 mg/kg) induces apoptosis, antiproliferation, reduces tumor cell self-renewal ability, impairs tumor vasculature, and decreases metastasis activity in breast cancer HCC1599 tumor-bearing mice. In various types of the breast xenograft models, PF-03084014 has significant antitumor activity (TGI>50%). |
| 细胞实验： |
Cell lines: Human T-ALL cell lines HPB-ALL. Concentrations: ~1 μM. Method: Cells are seeded in 96-well plates at 10,000 cells/well in growth media supplemented with 10% fetal bovine serum.Serial dilutions of PF-03084014 are done in DMSO,appropriate controls or designated concentrations of PF-03084014 are added to each well,and cells are incubated at 37℃ for 7 days (final DMSO content 0.1%).Resazurin at a final concentration of 0.1 mg/mL is added to the cells and plates are incubated for 2 to 4 hours.Fluorescent signals are read as emission at 590 nm after excitation at 560 nm. |
| 动物实验： |
Animal Models: Human T-cell acute lymphoblastic leukemia xenografts HPB-ALL. Formulation: 0.5% methylcellulose. Dosages: 150 mg/kg,b.i.d. Administration: p.o. |
