4、ChemE體外研究 Dasatinib potently inhibits wild-type Abl kinase and all mutants except T315I over a narrow range (IC501.7nM). Dasatinib (IC50: 0.8 nM) displays 325-fold greater potency compared with Imatinib against cellsexpressing wild-type Bcr-Abl in Ba/F3 cells 1.體內(nèi)研究 Daily treatment with Dasatinib (5

5、0 mg/kg) is initiated on day 10. Using this approach, a significant inhibition ofBCPAP orthotopic tumor growth is observed 6 days after treatment (day 16, P=0.014), which is sustainedthrough days 23 and 29 (P=0.0003), compared with vehicle-treated mice 3.

They are for reference only.Cell Assay 1 Ba/F3 cell lines are plated in triplicate and incubated with escalating concentrations of Imatinib, AMN107, orDasatinib for 72 hours. Proliferation is measured using a methanethiosulfonate-based viability assay(CellTiter96 Aqueous One

12、Solution Reagent). IC50 and IC90 values are reported as the mean of threeindependent experiments done in quadruplicate. The inhibitor concentration ranges for IC50 andIC90determinations are 0 to 2,000 nM (Imatinib and AMN107) or 0 to 32 nM (Dasatinib). The imatinibconcentration range is extended to
