Dasatinib (BMS-354825) (Synonyms: BMS 354825, Sprycel)

Cell lines

DU-145 and LNCaP cells

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months.

Reaction Conditions

100 nM, 6 hours for inhibiting FAK phosphorylation 24 hours for decreasing cell-to-cell contact

Applications

Dasatinib almost totally abolished the levels of p-FAK at Tyr576/577 in DU-145 cells, whereas p-FAK was not detected in LNCaP cells even though both cell lines expressed similar levels of total FAK protein. Treatment with 100 nmol/L dasatinib for 24 hours had no effect on cell viability and total cell numbers, although partial inhibition of cell proliferation due to G1 arrest was observed at 48 and 72 hours. Besides, there was a substantial loss of cell-to-cell contact in DU-145 cells. This effect may be related to the decrease in levels of p-FAK and p-p130CAS.

Animal models

Pdx1-Cre, Z/EGFP, LSL-Kras G12D/+, LSL-Trp53R172H/+ mice

Dosage form

Oral administration, 10 mg/kg, daily

Applications

There was no significant difference in survival between the different treatment groups. The median survival of vehicle-treated animals was 131 days compared with 127 days and 130 days for animals treated with dasatinib from 6 weeks and 10 weeks of age, respectively. Analysis of tumor burden in the mice showed that all mice had invasive PDAC; however, the number of mice with metastases was reduced significantly in dasatinib-treated animals. The incidence of metastases was 61.1% in vehicle-treated animals compared with 26.7% in mice treated with dasatinib from 6 weeks and 23.1% in mice treated with dasatinib from 10 weeks.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
